Coronation Gold Yarrow (Achillea 'Coronation Gold') is a vigorous tall growing yarrow with large golden-yellow flower heads. This non-reseeding variety blooms all summer and is considered to be one of the best yarrows for tolerating high humidity. It thrives when planted on a berm with heat and sun in poor soils including clay. Avoid rich soil, excessively windy sites, and too much irrigation.
Sunset Agastache (Agastache rupestris) is a cold hardy, native hybrid perennial that blooms from mid to late summer and sporadically into the fall. This variety features a profusion of orange and pinkish flowers that attract hummingbirds and bumblebees. Both the flowers and foliage have a strong minty licorice scent when touched, and aromatic foliage helps to deter both deer and rabbits. Having desert heritage, it resents poor drainage and winter moisture. To counteract that in Kansas, plant in full sun on berm with poor sandy or rocky soil with no irrigation.
Odora Elephant Ear (Alocasia odora) is typically grown in warmer zones and features giant glossy green leaves creating quite a contrast for other colorful flowers in the garden. Most alocasia are large tropical and subtropical herbaceous perennials with a giant tubers native to areas with a summer monsoon and dry winter. Along with other tropicals and succulents in Kansas, elephant ears are usually grown as summer patio plants. Fertilize, water regularly, and place in full sun. Protect from temperatures below 28 degrees F and move into a cold garage or basement over the winter with minimal watering. Do not allow the pot with rootball to freeze solid or go below 25 degrees for more than a few hours. Allow to go dormant as needed with little care, just cut off dead foliage and place back out in April or May with a time-release fertilizer. Many plants will die back slowly and remain attractive inside for most of the winter. You may also plant these in the ground for an enormous tropical effect! It is possible to overwinter these in the ground in Kansas by placing a giant 12-18" mound of mulch over deeply planted rhizomes. New growth will usually be delayed until June but quickly regains full height. In our trial gardens in Lawrence, KS (zone 6a), three established specimens planted over 12" deep and mulched 6-12" with leaf mulch survived -17 degrees F. During the arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 strait hours of 0 degrees F and mostly lower.
Portora Elephant Ear (Alocasia x Portora) is typically grown in warmer zones and features giant glossy green leaves creating quite a contrast for other colorful flowers in the garden. Most alocasia are large tropical and subtropical herbaceous perennials with a giant tubers native to areas with a summer monsoon and dry winter.

It is possible to overwinter these in the ground in Kansas by placing a giant 12-18" mound of mulch over deeply planted rhizomes. New growth will usually be delayed until June but quickly regains full height. This plant can also grow in standing water or as a potted plant in water gardens.
Regal Shields Elephant Ear (Alocasia x Regal Shields) features giant purplish-black leaves creating quite a contrast for other colorful flowers in the garden. Most alocasia are large tropical and subtropical herbaceous perennials with a giant tubers native to areas with a summer monsoon and dry winter. Along with other tropicals and succulents in Kansas, elephant ears are usually grown as summer patio plants. Fertilize, water regularly, and place in full sun.

Dutchman's Pipe / Woolly Pipevine (Aristolochia tomentosa) is one of the most rapidly growing vines in out library capable of growing 15-30' in one summer! Native to eastern North America including Missouri, it typically occurs along moist woods and along streams. It can fill a large trellis or arbor with bright green foliage up to 12" across creating the most dense shade of any vine. It needs typical garden soil and regular moisture and is intolerant of drought. In Eastern Kansas, typically our 40 inches of rainfall is close to sufficient without much extra water if planted in good soils. The flowers are 1-2" across but are usually not noticed but is absolutely gorgeous with foliage alone.
Italian Painted Arum (Arum italicum 'Pictum') is native to the Mediterranean region. It has a reversed or off-schedule life cycle; growing when other plants have already shed their leaves to take advantage of sunlight and lack of competition. It is often planted for its unusual evergreen leaf pattern and color resembling a bright green house plant growing outside in winter. Foliage goes dormant by June but is followed by naked stalks emerging from the ground with reddish orange berries. Foliage re-appears in fall and lasts well into winter untouched. If low temperatures hit 0 degrees F, foliage finally dies back to the ground and re-emerges in early spring to repeat the life cycle. If low temperatures hit -15 degrees F, it may kill an un-mulched plant; protect any zone 5/6 perennial with a 2-3" thick layer of mulch. Grow in average to rich well drained garden soil in full sun or full shade with everything in between. Moderate dry shade does not seem to be a problem because arum goes dormant anyways in the heat of summer. This holds true for planting in sunny locations to. Combine with shade garden plants that will fill the space in summer such as hostas or solomon seal. Also great when combined with late-emerging spring perennials (like plumbago, hardy hibiscus, and orange butterfly weed) because it fills that early spring space starting to grow extremely early with freeze-resistant foliage. Then later in the summer when Arum goes dormant, these plants hide the dying foliage and void left in the garden; what a great way for two species to share the same garden space! It has potential to be invasive in parts of the country such as the Pacific Northeast USA but not in Kansas. It is very stable but does not self-seed or spread in Lawrence, KS gardens; bulb offsets develop but only thicken the existing clump over time. Considered to be a great permatanet multi-season perennial for your garden.

Orange Butterfly Milkweed (Asclepias tuberosa) is a native wildflower with bright orange flowers occurring mostly in dry open habitats and is very common in the prairies and grasslands of the Midwest and Great Plains. Common in Kansas, this beautiful native wildflower is also found from Maine to South Dakota to the desert southwest to Florida. In ideal locations established Butterfly Weeds are very showy with multiple flowering stems spreading across the two foot high plant. Mature plants also have a deep tap root that extends down a foot or more allowing them superb drought tolerance. This rugged species thrives in sunny locations, in dry sandy soil or well-drained loam. More permanent locations include limestone bluffs, rocky prairies, and Great Plains. This wildflower also colonizes readily with wind blown fluffy seeds and will grow under the mower blades sometimes completing their flowering before yearly mowing along state highways. Foliage is often green, upright and attractive. Flowering is long lasting usually 4-6 weeks with interesting seed pods developing later. These eventually open and seeds float away. Reseeding is rare in the garden as mulch will generally eliminate that possibility. In the landscape, Orange Butterfly Weed can be used in any dry soil situation including berms, hot south or west side of the house, or any other full sun area. These will grow in poor rocky, sandy or clayish soils and even rich organic soils as a beautiful flowering annual. With our average 40 inches of rain per year in eastern Kansas, extra irrigation is not recommended. When used as an annual with irrigation and rich garden soil, you can expect the amazing growth and summer flowering followed by a probable root rot in the winter. Orange Butterfly Weed can be planted in parking lot medians and other hell strips as a very durable groundcover. Orange Butterfly Weed can also thrive in an above-ground perennial planter (with appropriate potting soil) year-round surviving the winter coldness in Eastern Kansas (zone 6a/5b). In any situation, combine with any other flower colors except orange. There is quite a lot of diversity within the species so plants from different locales will have different foliage and flower shades adapted to the site. Flower color can range from almost red to pure yellow and everything in between.
The False Indigo species (Baptisia) features beautiful compact bluish green leaves arranged in groups of three. Like many members in the legume family, they are nitrogen fixing plants which means they produce their own nitrogen in the soil through a symbiotic relationship with bacteria. The flowers bloom above the foliage normally in April and May. Common baptisia flower colors include white, purple, lavender, yellow, and pink as well as uncommon colors ranging from deep purple to maroon and even coppery orange. Considered a great North American native three season plant, the foliage always emerges very attractive followed by flowers that do not need deadheading. Foliage generally lasts pretty nice through hot summers and into fall turning black with first freeze. Seed pods also turn charcoal black when ripe and have considerable ornamental interest and useful in dried flower arrangements. At some point in the fall, it can be cut down early for a clean look or left for winter interest. Baptisia generally do well in droughty clay soils in full to part sun. There is only one pest that may create problems called the Genista Broom Moth. It may occur in Kansas when weather conditions are consistently dry and over 95 degrees F. It is treatable if you act fast but if not, it only destroys the foliage late in the season and does not kill the plant. Baptisia has several enormous spreading taproots which store water and energy and can make transplanting difficult. Plantings look good as specimen or in small groups; and it’s ok even preferable if they grow together and touch other plants. That helps eliminate available sunlight and discourages weeds. It is hard to picture a native plant garden or any perennial garden without Baptisia. Considered a once “it’s there, it’s always there” plant. Baptisia 'American Goldfinch' >>>>>>>Gorgeous, golden yellow flower spikes rise up above its wide habit. This is one of the most floriferous Baptisia we offer, producing loads of brightly colored spikes for many weeks. After the blooming season, 'American Goldfinch' produces attractive round seed pods in the fall. This is the perfect specimen for filling in a large space in your garden or for mass plantings in landscapes. >>>>> This extremely long-lived perennial could be used instead of a shrub in landscape settings, with minimal care required to thrive year after year.

Baptisia 'Lemon Meringue' is an excellent vigorous yellow flowered selection. It forms an upright, vase-shaped mound of attractive blue-green foliage topped with long, charcoal stems which carry the lemon yellow flowers in late spring to early summer. The contrast of dark stems with light flowers really pops in the landscape, delivering an excellent floral display. Ornamental seed pods extend the season of interest into fall. This extremely long-lived perennial could be used instead of a shrub in landscape settings, with minimal care required to thrive year after year. This plant is a member of the DECADENCE® series from Walters Gardens, Inc.

Bright and cheery, this new barberry (Berberis 'Sunjoy Tangelo') has vivid orange new growth that develops a distinctive chartreuse margin as the season goes on. Sunjoy® Tangelo Barberry is stronger growing than other variegated cultivars, it is colorful in the landscape from spring to fall. Certified wheat-rust resistant. Maintenance Notes: Prefers well-drained soils. May be pruned to shape in summer. In Eastern Kansas, this cultivar performs WELL with just about everything nature has to challenge it! Heat and drought are tolerated well. Cold tolerance is no problem. No disease or pest problems. Great plant for berms in full sun. No other plant can match its bright orange-red foliage: I personally love the combination of planting next to blue or purple flowers but the combinations are endless! All Proven Winners® plants are legally propagated, healthy and vigorous, true to name, and tagged with color pictures and growing information.
Hardy Bird of Paradise (Caesalpinia gilliesii) is a surprisingly hardy shrub from South America native to Argentina and Uruguay. The extremely fine textured bipennate foliage is fern-like and resembles Mimosa or Amorpha. During spring and summer the lovely foliage takes on a bluish green color. By late summer if conditions are optimal, beautiful flowers appear. The flowers are light yellow with protruding red hair-like stamens that are very showy, drawing in curious visitors. By late fall in our zone 6 climate, the foliage drops and typically the above ground woody part of the shrub freezes back and behaves like a Crapemyrtle or a Butterfly Bush. Trim dead growth in mid-spring and enjoy the new beautiful regrowth by early summer. In order for this shrub to flower, it needs to be well-established, in full sun, and preferably on the south or west side of a foundation. Hardy Bird of Paradise need average to dry well drained soil especially in the winter. Hardiness should not be an issue after seeing mature established plants at the Denver Botanic Garden (zone 5b) in full bloom. The Botanic Garden at Oklahoma State University (zone 7a) also has a few decades old specimens. Wet winter soils could limit its success in zone 5-7 areas in the Eastern United States. It has been thriving in our trial gardens and at several residential gardens in Lawrence, KS (zone 6a) 5-7 years ago. During the arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 straight hours of 0 degrees F and mostly lower. It is virtually unknown in most garden centers but worthy of more wide-scale use especially in hot locations.
Cannas are typically grown for their continuous summer flowers and vertical wide-leaf foliage. The plants are large tropical and subtropical herbaceous perennials with a rhizomatous rootstock native to areas with a summer monsoon and dry winter. They can be grown as flowering summer patio plants. If growing as a potted plant and trying to overwinter, allowing the foliage to frost is ok, it will not kill the root system. However, do not allow the pot with rootball to freeze solid or go below 20 degrees for more than a few hours; move into a cold garage or basement over the winter with no watering. Cut back and allow to go dormant and place entire pot back out in April or May with a time-release fertilizer. Another more labor intensive way to overwinter cannas is to remove them from the dirt, dust with fungicide, place in box with sawdust, and keep in the refrigerator. We consider this method old-fashioned and too much work but ok if you only want to save a few pieces. If digging from the ground, just save a chunk with the dirt intact and place into a large pot in the garage. During the growing season, fertilize, water regularly, and place in full sun. You may also plant these in the ground for an enormous tropical effect! It is possible to overwinter these in the ground in Kansas by mulching 4-8" thick over deeply planted rhizomes. New growth will usually be slightly delayed but quick to regain full height. In our trial gardens in Lawrence, KS (zone 6a), the following varieties survived after being mulched 6-12" with leaf mulch to -17 degrees F. (Canna 'Daddy's Buckaroo',Canna 'Omega',Canna indica 'Red Stripe',Canna indica 'Ellen's Super Orange', Canna indica 'Wyoming') During the arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 straight hours of 0 degrees F and mostly lower. Canna glauca 'Panache' is a native canna to South-east U.S. with blue-green leaves and salmon-pink to peach flowers. This canna can also grow in standing water as a potted plant or in a rain garden.
Yellow Candlestick Tree (Cassia / Senna alata) is grown in Kansas as a giant annual capable of reaching 6 to 12 feet in one season. Growth is slow at first in Spring when temperatures are still cool. It is native to tropical rainforests in Mexico and South America generally fulfilling the role of a pioneer species rapidly colonizing disturbed areas. Bright green bi-pinnate leaves are symmetrically arranged and very tropical looking. As branching and growth form develop, the overall geometrical effect is stunning even without flowers yet. Finally by September and all through October until frost, yellow candle-like flowers tower over the foliage. Some plants may have up to 50-100 flower spikes at one time. Cut down promptly after frost as there is no winter interest. Seeds rarely have time to develop in our shorter growing season but it is possible to harvest seeds if the first fall freeze is late. Yellow Candlestick Tree grows fastest in rich well drained soils and plenty of water. Growth is equally impressive in most Kansas soils including heavy clay as long as watering is sufficient. Yellow Candlestick Tree needs hot summers, full sun, and warm humid conditions to thrive. When grown in a large pot, it is very difficult to overwinter inside so it’s best to buy new plants each year. This plant has also evolved and interesting relationship with ants, providing nectary glands (food) in exchange for protection from insect pests. Use Yellow Candlestick Tree where you need to fill up a lot of space in a hurry or just like lots of yellow flowers in the fall when other things are not blooming. Interestingly, the foliage is sensitive to light, folding up neatly at sunset and opening up the nest morning.

Grown for its beautiful bluish-green skin and showy night-blooming white flowers. Unlike most columnar cacti, Peruvian apple cactus (Cereus peruvianus) will bloom at a young age in a pot when about 3' tall or more. This cactus is usually grown as a patio or house plant in Kansas and blooms in late summer into early fall. Flowers only last one night! In the wild, this species is hardy to 20-25 degrees F for short periods of time. Grow in full sun with optional extra watering including that which comes from rainfall. Repotting may or may not be needed depending on how large you want the plant to grow; plants can continue to grow taller and tolerate extremely root-bound pots but may need wind bracing. If repotting, make sure to use a sharp draining medium organic cactus mix with plenty of sand and perlite. To play is safe, potted plants are best moved in before night temperatures get below 45 degrees F. It is important to avoid the combination of wet and cold. Before extreme cold occurs, move to a bright interior window over the winter with no watering and keep above freezing. As a winter house plant, it will look presentable all winter long with just no waterings. As a permanent house plant, provide bright light and allow the soil to dry between waterings for many years of carefree enjoyment. Plants grown permanently indoors may begin to elongate stretching for light producing weak new growth. It can be hard to reproduce the intense UV sunlight they need so moving outside for the summer is best. Generally if moving outside for the summer, allow 1-2 weeks of part shade or morning sun before placing in full sun. Plants with time to acclimate will thrive in full sun but be careful not to rush it or sunburning will occur. Potted plants are very low maintenance. I have never seen any insect problems on this plant. Potted plants are capable of growing 10' tall or more in a small 7gal pot.
Pink China Hardy Elephant Ear (Colocasia 'Pink China') are typically grown for their large tropical foliage and pink stems. The plants are temperate and subtropical herbaceous perennial bulbs native to areas with a summer monsoon season and dry winter. Pink China Hardy Elephant Ear is hardy outside as a perennial when established and with minimal effort at least up to zone 6a. During the growing season, fertilize, water regularly, and plant in full sun. Plant these bulbs in the ground at least 3-6" deep with 3-4" of mulch. Foliage may look bedwraggled by fall if drought stressed so it is ok to cut back foliage at that time. Plants spread by running ryizomes but are easy to pull up if undesired. They can also be grown as a flowering summer patio plant. If growing as a potted plant and trying to overwinter, allowing the foliage to frost is ok, it will not kill the root system. However, do not allow the pot with rootball to freeze solid or go below 20 degrees for more than a few hours; move into a cold garage or basement over the winter with no watering. Cut back and allow to go dormant and place entire pot back out in April or May with a time-release fertilizer. If digging from the ground in colder zones, just save a big chunk with the dirt intact and place into a large pot in the garage. In our display garden in Lawrence, KS (zone 6a), several established specimens planted over 4-6" deep and mulched 2-3" with wood mulch survived -17 degrees F. During the arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 straight hours of 0 degrees F and mostly lower. This plant can also be used as a marginal aquatic plant growing in shallow water. It can also grow as a bog plant needing constantly moist soil rich in organic matter. As a rain garden plant, it will thrive is a depressed area in the landscape that collects rain water from a roof during spring and summer periods of rain but then go dormant if the water hole dries out completely.
Zagreb coreopsis is a compact gold flowering variety with fine textured foliage. Coreopsis is native to most of eastern North America. Flowers occur in midsummer for a few weeks then turn black to add some interest. Foliage is a rich green turning to yellow briefly in the fall. It spreads gently by rhizomes with density is quite thick to the point where no other weeds usually grow within its space. Zagreb prefers full sun and average to rich well-drained garden soils. Irrigation is not normally necessary except during periods of drought. Rabbits can be a problem young immature plants. A popular method of control is covering the plant with an upside down bowl-shaped chicken wire cage for the first year to allow basil foliage to establish well. You can quickly make these yourself with a low cost roll of chicken wire. Mature plants especially in groups with other mature landscaping generally do not have rabbit problems. The rich yellow golden flowers combine well with most other flowers. The fine textured foliage combines well with medium or course textured plants. Most coreopsis are not long-lived plants but this variety of coreopsis seems to be the most durable in the garden lasting several years or more.
Harry Lauder's Walking Stick / Contorted Filbert, is also known as Corylus avellana 'Contorta'
>>>>>A feast for the eyes from spring through autumn! Winecraft Black® Smoketrtee (Cotinus 'Winecraft Black') is the first Proven Winners smokebush, so you know it must be special. In spring, round leaves emerge rich purple but as summer's heat comes on, they turn a deep near-black tone and finally light up in an array of reds and oranges in fall. In early summer, large, soft panicles of bloom appear that become the misty "smoke" that makes this such a popular landscape plant. Unlike other smokebush, it naturally has a rounded, dwarf habit which means that finally, every landscape has room for this unique plant. Top three reasons to grow Winecraft Black smokebush: 1.Color and interest from spring through frost. 2.No pruning or special maintenance required. 3.Dwarf habit makes it easy to use with any sized home or yard. Uses Notes: Smokebush makes a striking specimen, but is also effective as a low hedge or mass planting. Maintenance Notes: Winecraft Black smokebush is very easy to care for and requires little to nothing in the way of regular maintenance. Plant in full sun for best color and flowering. Pruning will rarely be required but may be done in spring. It isn't technically the flowers that create the hazy, smoke-like effect this plant is so loved for - it's the seed pods that form after the flowers have faded. In Eastern Kansas, this cultivar performs WELL with just about everything nature has to challenge it! Heat and drought are preferred and need hot microclimate. Cold tolerance is no problem. Some leaf disease appears by late season from excessive rains and high humidity sometimes causing early defoliation. An important note about pruning: Do not attempt to rejuvinate an older tree/shrub in early fall. This will trick it into growing back rapidly to recover and them WHAM!....Arctic cold blast arrives killing any new growth not hardened off. This double sapps the tree for nutrients usually resulting in death by spring. All Proven Winners® plants are legally propagated, healthy and vigorous, true to name, and tagged with color pictures and growing information.
>>>>>A beaming beacon for the landscape. Bold, bright, and beautiful: that's Winecraft Gold™ Smokebush (). Round, waxy leaves emerge a sunny orange, soon take on a golden hue, then mature to a cheerful chartreuse for the season. In early summer, cloud-like green flower clusters cover the plant, and these turn into the pink "smoke" plumes that earn the plant its name. Naturally grows with a dense, oval shape that's ideal for adding a spot of bright color to partially shaded or sunny areas. Top reasons to grow Winecraft Gold smokebush: 1. bright golden foliage, 2. memorable smoke-like seedheads in summer, 3. smaller and more dense than conventional smokebush. Uses Notes: Makes a lovely specimen or addition to perennial gardens and flower borders. Maintenance Notes: It's best to avoid pruning smokebush regularly, though you may selectively remove branches to attain the shape you desire. It's quite versatile and easy to grow, but do note that this golden selection is a bit less cold tolerant than other smokebush.

Buffalo Gourd (Cucurbita foetidissima) has large, gray-green, triangular leaves growing along long, prostrate stems. In the wild, the plants are often 20-30 feet across. Leaves are an attractive bluish green with a sandpapery texture. The large, bell-like flowers, 2-4 inches long, are yellow to orange, opening for only a day but blooming occurs over a month or so. The globular fruits, about 4 inches across, are green-striped when young, maturing to tennis-ball size and turning yellow. The plant supposedly gets the name "stink gourd" from its foul odor. Native to arid clay soils in Western Kansas, Colorado, the southwestern United States, and northern Mexico, the plant forms a fleshy tap root which is used to store water and nutrients. A large 10' wide specimen has flourished in our display garden in Lawrence, KS for over 10 years. It is planted in full sun in clay soil with no extra irrigation. It survived -16 degrees F and a week of single digit highs in February, 2021. It would be very useful as a vine-like perennial cascading over the top of a retaining wall! Amazing that a perennial native to areas receiving 5-10" of rain per year can grow in a climate receiving 5-10 times more rain!
Texas Sotol (Dasylirion), is also known as Dasylirion texanum. Narrow green leaves and saw toothed edges make an excellent architectural statement. Stiff leaves can get 3-5' tall and 3-4' wide. Flowers are white to cream colored. Texas Sotol can be used as a patio plant in Kansas. Place in full sun with no extra watering except from rainfall. Repotting may or may not be needed depending on how large you want the plant to grow. Potted plants are hardy to at least 10 degrees F if kept dry so you can wait awhile to move these in for the winter. Then move into a cold garage, basement, or window over the winter with NO watering. Although un-tested by the author, this species could survive in a microclimate under a south facing roof overhang kept completely dry in the winter and controlled water in the summer in zone 6a. Several plantings in Tulsa, Oklahoma at the Gathering Place endured temperatures as low as -11 degrees F along with prolonged cold (5 days of highs in the teens and lows in the single digits) in February, 2021.

Yellow Coneflower, is also known as Echinacea paradoxa
Golden Barrel Cacti (Echinocactus grusonii) are known for their bright yellow spines. Native to deserts in Mexico, it's usually grown as a patio or house plant in Kansas. In the wild, established golden barrel cacti are hardy to 13 degrees F for short periods of time. Grow in full sun with no extra watering except that which comes from rainfall. Repotting may or may not be needed depending on how large you want the plant to grow; plants can continue to grow taller and tolerate extremely root-bound pots but may need wind bracing. If repotting, make sure to use a sharp draining low organic cactus mix with plenty of sand and perlite. Potted plants are hardy to at least 25 degrees F for a short time if kept dry so you are ok if you miss the first light frost. Do not allow the pot with rootball to freeze solid though. Before extreme cold occurs, move to a bright interior window over the winter with no watering and keep above freezing. As a winter house plant, it will look presentable all winter long with just no waterings.(also to prevent soft winter growth) As a permanent house plant, provide bright light and allow the soil to dry between waterings for many years of carefree enjoyment. Plants grown permanently indoors may begin to elongate stretching for light and lose their spine color. It can be hard to reproduce the intense UV sunlight they need so moving outside for the summer is best. Generally if moving outside for the summer, allow 1-2 weeks of part shade or morning sun before placing in full sun. Plants with time to acclimate will thrive in full sun but be careful not to rush it or sunburning will occur. Potted plants are very low maintenance. I have never seen any insect problems on this plant.
Grown for its beautiful bluish-green skin and relatively few spines, San Pedro Cactus () is usually a patio or house plant in Kansas. Because it grows naturally in the Peruvian Andes Mountains at high altitude and with high rainfall, it can withstand temperatures far below that of many other cacti. In the wild, this species is hardy to 15-20 degrees F for short periods of time. Grow in full sun with optional extra watering including that which comes from rainfall. Repotting may or may not be needed depending on how large you want the plant to grow; plants can continue to grow taller and tolerate extremely root-bound pots but may need wind bracing. If repotting, make sure to use a sharp draining medium organic cactus mix with plenty of sand and perlite. To play is safe, potted plants are best moved in before night temperatures get below 45 degrees F. It is important to avoid the combination of wet and cold. Before extreme cold occurs, move to a bright interior window over the winter with no watering and keep above freezing. As a winter house plant, it will look presentable all winter long with just no waterings.(also to prevent lanky winter growth) As a permanent house plant, provide bright light and allow the soil to dry between waterings for many years of carefree enjoyment. Plants grown permanently indoors may begin to elongate stretching for light producing weak new growth. It can be hard to reproduce the intense UV sunlight they need so moving outside for the summer is best. Generally if moving outside for the summer, allow 1-2 weeks of part shade or morning sun before placing in full sun. Plants with time to acclimate will thrive in full sun but be careful not to rush it or sunburning will occur. Potted plants are very low maintenance. I have never seen any insect problems on this plant. The San Pedro cactus contains a number of alkaloids, including the well-studied chemical mescaline. In the US, it is currently legal to cultivate the San Pedro cactus for gardening and ornamental purposes, but not for consumption.
Barrenwort (Epimedium) features compact dainty mounds of green to colored weed-resistant foliage. Wispy flowers appear above emerging foliage in mid-spring. Improved breeding has resulted in many different flower colors even including orange. Semi-evergreen foliage can sometimes look bedraggled by late summer if there is too much overhead watering and humidity. Barrenwort prefers average to dry garden conditions and even thrive and dry shade. Plantings can thrive for decades if in the right spot; there is no such thing as overcrowding for Barrenwort. When planted in mass, growth is slow at first but eventually a cake-like rhizome system will form and completely smother out any weeds and compete well with trees for water and nutrients. While barrenwort can tolerate full sun, they prefer part to full shade. Sun burning is possible with temperatures over 100° and there are better plants to use in hot areas. Due to slow spreading growth, you shouldn't leave very much room in-between barrenwort plants or you will be waiting many years for the patch to fill in. Weeds can be a problem in that open area between plants if spacing is too wide. We recommend 9-12" spacing and use for small nooks in the shade garden. If planning for a larger area, still figure on the tight spacing but allow for a higher budget that you will consider a permanent investment. Barrenwort is a real trooper for the dry shade garden! Epimedium 'Amber Queen' features airy, delicate-looking flowers that have bright yellow spurs with orange-red centers, looking light orange from a distance. Flowers are produced along the length of the flower stems, which are up to 24" long. Bright green leaves have a blush red color close to the crown. Growth is faster and height is taller at 12-24" Albeit still slower when compared to other perennials.

Robin's Plantain / Fleabane, is also known as Erigeron pulchellus var. pulchellus 'Lynnhaven Carpet'
Robbie Spurge (Euphorbia amygdaloides var. robbiae) is grown for its deep green glossy whorled foliage that is very architectural and symetrical. They have everything a gardener might ask for; beautiful spring flowers, dependable dark green foliage, evergreen during winter, pest-free foliage, and ease of care with very low maintenance. Rare greenish-yellow flowers last incredibly long 1 to 2 months and finally turn brown in need of dead-heading. Native to dry woodland locations in Europe, Turkey and the Caucasus, Robbie Spurge tolerates poor soils, including rocky-sandy ones. Root rot can be a problem in poor drainage areas. It prefers average to dry garden conditions with dappled or morning sun. Sun burning is possible with temperatures over 100° so avoid full afternoon sun. Plantings can thrive for many years if in the right spot and there is no such thing as overcrowding. The growth rate is slow at first but eventually forms a nice weed resistant cover so space new plants relatively close together is desiring this effect. Evergreen foliage is hardy to about -10°F with complete death occurring at about -15°F for unmulched plants. Robbie Spurge is less adapted to consistent summer heat and humidity of zone 7b areas or South. With poisonous foliage, these plants resist deer and rabbit browsing. What a great plant for the dry shade garden!
Donkeytail Spurge (Euphorbia myrsinites) is grown for its powder-blue/silver whorled foliage that is very architectural and symetrical. The stems creep along the ground in several directions from the main stem. Beautiful spring flowers are chartruse and foliage is solidly evergreen during winter and completely pest-free. Native to rocky and grassy places of southeastern Europe and Asia Minor, Donkeytail Spurge tolerates a wide range of growing conditions except excess moisture. Performance is best in poor soils, including rocky-sandy ones. Root rot can be a problem in poor drainage areas. It prefers full sun but can also grow well in full dry-shade. Individual plants tend to be short lived so allow some self seeding to occur within the group of plants. Due to self-seeding, it is considered a noxious weed in several western states and should not be planted in those areas. However, it is not a problem in Eastern Kansas or further East areas with over 35 inches of rainfall per year. Do not plant in rich moist soils or root rot will probably occur. Donkeytail Spurge is less adapted to consistent summer heat and humidity of zone 7b Southeast parts of the United States. With poisonous foliage, these plants resist deer and rabbit browsing. Wear gloves when handling this plant and avoid the milky sap. Great plant for berms or clammoring over retaining walls in hot West or South exposures in full sun or the opposite full dry-shade!
Fire Barrel Cacti (Ferocactus sp.) are known for their bright red spines. Native to the Mojave desert south to the desert of Baja California, it's usually grown as a patio or house plant in Kansas. In the wild, some fire barrel species are hardy to 20 degrees F. Grow in full sun with no extra watering except that which comes from rainfall. Repotting may or may not be needed depending on how large you want the plant to grow; plants can continue to grow taller and tolerate extremely root-bound pots but may need wind bracing.

It can be hard to reproduce the intense UV sunlight they need so moving outside for the summer is best. Generally if moving outside for the summer, allow 1-2 weeks of part shade or morning sun before placing in full sun. Plants with time to acclimate will thrive in full sun but be careful not to rush it or sunburning will occur. Potted plants are very low maintenance but watch for scale and mealybugs that may hide beneath the cover of spines.
Show Off® Forsythia (Forsythia x Mindor 'Show Off') "shows off" its bright yellow early spring flowers. Improved flower display compared to older varieties. Compact. Deer resistant. Good for cut displays. An excellent specimen plant for mixed borders and foundations. Prefers a good loose soil, but will do well in any soil. pH adaptable and withstands city conditions and is air pollution tolerant. Pruning is best done immediately after flowering. Old stems can be removed or can be cut back to the ground. Shaping should be done at this time. Prefers medium moisture. Fertilize in early spring by applying a slow release fertilizer specialized for trees and shrubs. Follow the label for recommended rate of application. This little beauty will be a blast of early spring color from the ground up! Show Off is not your typical forsythia! It is compact and full of blooms from the ground to the end of every stem. Older varieties can become out of control and often become victims of bad pruning; this little beauty will stay small so there is less need to prune. Now you can have a nice tight, compact forsythia hedge without doing any work! A real improvement over older varieties, Show Off is a very showy choice for the early spring garden. In Eastern Kansas, this cultivar performs WELL with just about everything nature has to challenge it! All Proven Winners® plants are legally propagated, healthy and vigorous, true to name, and tagged with color pictures and growing information.
Arizona Sun Blanket Flower (Gaillardia aristata 'Arizona Sun') is an improved variety with an intense covering of red and yellow flowers in the summer. Blooming usually starts during the heat of summer and continues until frost. Foliage is mint green and attractive. Blanket flower is native to dry sandy areas of the lower great plains including Texas, New Mexico, and Arizona. Because of its desert heritage, it resents cold wet winters and needs well drained sandy, silty, or rocky soil. Short periods of extra water is tolerated in the heat of summer especially after blooming has started. It will typically grow in any soil and bloom like crazy during the summer making it very useful even as an annual if planted in the wrong soil type. In Kansas landscapes, it is commonly used as an annual or short-lived perennial where lots of color is needed in full sun. Self-seeding is possible in areas that are not mulched. Gaillardia combines nicely with any blue or purple flower including catmint, false indigo, plumbago.
Raintree Hardy Gladiolus (Gladiolus 'Raintree') are typically grown for their mid-summer flowers and vertical iris-leaf foliage. The plants are temperate and subtropical herbaceous perennial bulbs native to areas with a summer wet season and dry winter. Gladiolus are hardy outside as a perennial when established and with minimal effort at least up to zone 6a. During the growing season, fertilize, water regularly, and plant in full sun. Plant these bulbs in the ground at least 6-8" deep with 3-4" of mulch to enjoy a wonderful tropical flowering effect! Foliage may look bedwraggled by fall so it is ok to cut back foliage at that time. They can also be grown as a flowering summer patio plant. If growing as a potted plant and trying to overwinter, allowing the foliage to frost is ok, it will not kill the root system. However, do not allow the pot with rootball to freeze solid or go below 20 degrees for more than a few hours; move into a cold garage or basement over the winter with no watering. Cut back and allow to go dormant and place entire pot back out in April or May with a time-release fertilizer. Another more labor intensive way to overwinter gladiolus is to remove them from the dirt, dust with fungicide, place in box with sawdust, and keep in the refrigerator. We consider this method old-fashioned and too much work but ok if you only want to save a few bulbs. If digging from the ground in colder zones, just save a big chunk with the dirt intact and place into a large pot in the garage. In a customer's garden in Lawrence, KS (zone 6a), four established specimens planted over 4-6" deep and mulched 2-3" with wood mulch survived -17 degrees F. During the arctic blast of February, 2021, lows down to -17 degrees F on Feb 16th, 2021 were recorded. The longevity of this cold blast was also impressive: 10 days on a row with highs of 10-15 degrees F or lower, 8 nights of lows in the single digits and negatives, and 36 straight hours of 0 degrees F and mostly lower. We plan to propagate these 'Raintree' clones in 2022-2023.
