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 'Omega' is a tall variety with blue-green leaves and orange flowers. This variety is the most cold hardy of the cannas due to its vigorous deep growing rhizomes. The rate of spread is faster so provide a larger space for this plant. This canna can also grow in standing water as a potted plant in water gardens or rain gardens.

Carex appalachica, commonly called Appalachian Sedge, is native to It is native to the eastern North America, where its typical natural habitat is dry forests and woodlands. It forms a weed-suppressing grass-like clump 12" tall with brown seed heads dangling above. Bright green foliage is extremely fine-textured and hair-like. White-Tinged Sedge is one of the most drought tolerant of the sedges earning a spot in the dry shade garden; it cannot handle extreme drought or extremely rootbound soils though. 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.
>>>>>Oak Sedge (Carex pensylvanica) is planted for its attractive grass-like green foliage>>>>>. Foliage maintains well all year provided that certain cultural conditions are met. Carex plantaginea is native to rich deciduous forests in the eastern United States up to Canada. While it excels in moist shaded sites in calcareous soils, it can adapt to difficult dry shaded sites quite well once established. If low temperatures hit 5 degrees F, foliage finally back to the ground and re-emerges in early spring. Generally this plant can decline after a few years of Kansas climate but worth a try in reasonable soils in well-tended shade gardens. Tolerates moderate dry shade with regular weeding: competition with weeds seem to be an issue in low maintenance gardens.

Dark Knight Caryopteris (Caryopteris x clandonensis 'Dark Knight') features darker green summer foliage followed by late-summer deep blue flowers and a compact growing habit. It adds much-needed color to the late summer landscape and makes a handsome companion with perennials. A great favorite with pollinators of all types (bees, butterflies, and hummingbirds) in the late season garden. Caryopteris demands a sunny spot and very well-drained soil. Wet soils, particularly those that remain soggy during periods of cold weather, will cause root rot. For this reason, we recommend early season planting of caryopteris in zones 5. 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 for us in zone 6. Caryopteris gives great winter interest with it's dried flowers. The only maintenance this shrub needs is cutting back about 1/2 way in early spring before new growth emerges. No disease or pest problems. Great plant for berms or hot West or South exposures in full sun. Do not plant in rich moist soils or root rot will probably occur. Even when not blooming, the compact green foliage looks good on it's own or combines well with earlier season blooming red, purple, blue, or magenta flowering plants. Combine with crapemyrtles and butterflybush to create a late season "all you can eat" buffet for pollinators!
First Choice Caryopteris (Caryopteris x clandonensis 'First Choice') blooms earlier than other earlier caryopteris. This shrub develops a compact, tight habit with dark green foliage and deep blue long-lasting flowers. 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 for us in zone 6. Caryopteris gives great winter interest with it's dried flowers. The only maintenance this shrub needs is cutting back about 1/2 way in early spring before new growth emerges.

Sunshine Blue® II Bluebeard (Caryopteris x clandonensis 'Sunshine Blue II') is the hardiest caryopteris yet! Sunshine Blue II is a new, improved variety of the classic Sunshine Blue, but it's much more tolerant of cold climates. If you've had trouble with bluebeard surviving winter in your area in the past, now's your chance to enjoy the vivid gold foliage and blue blooms of this late blooming favorite. An excellent plant for attracting pollinators! Top reasons to grow Sunshine Blue II caryopteris: 1.The hardiest caryopteris yet - survives winter even in the Midwest. 2.Colorful all season, especially late in summer when blue flowers appear. 3.Thrives in hot, dry, sunny spots. Maintenance Notes: Plant bluebeard in full sun and well-drained soil. Though Sunshine Blue II tolerates colder conditions than other caryopteris, it will do best if you avoid planting it in spots where the soil is cold or wet in winter and early spring. Cut back hard in spring, after the new growth emerges. Avoid late season planting in coldest parts of its hardiness range. 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 for us in zone 6.

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.

Blue Atlas Cedar (Cedrus atlantica 'Glauca') is an outstanding ornamental conifer tree with the characteristic conical shape and bluish-silver color. Foliage density is very compact along the branches but with plenty of space between branches, enough to show off the wonderful architectural branching structure of the tree. It is cold and drought tolerant enough to survive in much of Kansas with mature specimens (15-30' tall) occasionally seen in Lawrence and Kansas City. In Eastern Kansas, typically our 40 inches of rainfall is sufficient without extra water if planted in good soils. Avoid poorly drained clay soils especially that hold water for more than a day. Numerous cultivar selections are available, many for improved blue color of the needles or different growth forms. There is at least one "weeping" selection that I have witnessed prospering in Lawrence, KS for many years surviving -16 degrees F and a week of single digit highs in February, 2021.

Flamingo Feather Celosia (Celosia argentea var. spicata 'Flamingo Feather') is a large magenta flowering annual. Growth starts off in May when temperatures have warmed. Beautiful dark green foliage has reddish colored back sides of the leaf and magenta stems. After achieving about 3 to 4 feet in height and wide, fuzzy magenta flower spikes begin to appear usually by July. Ultimate height can reach 5-6 feet as flowering becomes more dense and continues until frost providing an excellent long-lasting show. Celosia has little winter interests so you may cut down promptly after the first fall freeze. This is a time to save some of the seeds if you wish to sprinkle them in a new area next year. You may or may not enjoy the fact that the Celosia will easily re-seed itself in areas that you do not mulch. Seedlings come up rather late and can create a carpet under the previous years planting location. We usually allow self-seeding to occur in our display garden in select areas and then spray Roundup or mulch wherever you do not want seedlings. Flamingo Feather Celosia needs full sun for best flowering but tolerated virtually any soil conditions including compacted driveway gravel. Use Flamingo Feather Celosia where you need to fill up a lot of space in a hurry or just like lots of magenta flowers in the fall when other things are not blooming. Celosia is also grown as a food crop in Africa and Southeast Asia.
Button bush (Cephalanthus occidentalis) is a beautiful rounded shrub with glossy green leaves that turn reddish maroon in fall. White flowers are very unique (and look like a coronavirus) consisting of small spheres with protruding anthers. Bloom occurs all summer and are attractive to many different bee and butterfly species, including the swallowtail butterfly. Red fruiting heads appear in late summer adding to the ornamental appeal! In its native habitat covering most of Eastern United States including disjunct populations in Arizona, California, and Mexico, this wetland shrub can be found in low-lying areas. This includes swamps, marshes, bogs, wetlands, and along the edges of ponds, streams, and rivers. In Eastern Kansas, this is a no-brainer shrub to small tree for average garden soils including heavy clay and useful for rain gardens. Adapts to a wide range of soils except dry ones if in poor soils. Tolerant of moderate drought once established especially if in moisture-retentive rich soils. As a testament to this plants survivability, Clinton Lake and Perry Lake located in NE kansas flooded in 2020 with areas of shore-line underwater for the entire growing season. This killed every other plant species was killed except for buttonbush: all top growth was killed but new shoots from the root systems of thousands of plants along the shore resumed the following year when water receded. Basically, these plants survived over 18 months with no growth from fall of 2019 to spring of 2021. This plant can also grow in permanent standing water or as a potted plant in water gardens. Sugar Shack® Buttonbush (Cephalanthus occidentalis 'Sugar Shack') in a new Proven Winners variety! Although buttonbush has long been prized as a native and great for rain gardens, it was way too big for most landscapes. Not anymore! They cut the size in half and added improved colorful red fruit and glossy foliage. Add in cool looking, fragrant white flowers and you've got a delightful plant that shines from spring to fall. Blooming on new wood, button bush may be trimmed in early spring. Complete rejuvenation may also be done if plants get too big.
Creeping Plumbago / Leadwort (Ceratostigma plumbaginoides) is a Chinese native plant well adapted to our climate without being invasive in Kansas. It features nonstop royal blue flowers from midsummer till hard freeze; Usually three months or more. After a first light freeze, if flowering is still occurring, rich green foliage will turn bright red while still containing a few blue flowers. This creates a one-of-a-kind contrast not seen in any other plants. Plumbago combines well with just about any other plant due to its rare flower color. This is especially dramatic is combining it with opposites on the color wheel like orange, red or yellow. Growth is often slow to emerge in the spring as plumbago needs warmer soil than most other plants to start growing. This allows for a good combination for spring bulbs to grow with plumbago coming up later to hide the dying bulb foliage. In Kansas landscapes, plumbago is often used as a full sun groundcover in hot areas such as west or south side of the house. Normal garden conditions and berms are fine as well. Plants can survive and flower in shade but growth will be much slower and risk of death will be present until established. In zone 6a, all plantings should be mulched and only larger size established pots should be planted if in the fall. Plumbago sold in flats of many smaller plants can safely be planted in spring or summer. Plumbago needs medium to dry soil tolerating clay as long as everything as well-drained. Once plants are established for a season or two in full sun, they are nearly indestructible. Slow spread will occur and plants will develop very high density smothering out weeds. Sometimes the slowly spreading growth (underground rhizones) can be a problem after a decade or so. However, if you plan ahead and use it as a groundcover like intended, it will be perfect. Being a very low maintenance plant not requiring extra watering or deadheading, the only thing you need to do is weed-eat or cut back all the foliage in the winter. Plumbago has no pest or disease problems.

Cercis canadensis Burgundy Hearts® is an improved reddish purple-leaf variety developed by Greenleaf Nurseries in Oklahoma. Burgundy Hearts more drought and heat tolerant. Pinkish-lavender April flowers bloom for about a month before leaves appear. It has a more or less rounded form, wider than it is tall. This small deciduous tree is known for its heart-shaped leaves that hold their dark color longer in the summer, taking on reddish wine tones towards the fall. Many of the problems with the regular species redbud tree are not an issue with this improved cultivar. It is to be expected however that all Redbuds have a relatively short lifespan of 20-40 years but even so, are worth planting for its beautiful flowers. It is not weak wooded and makes a nice hot non-sparking firewood. The short life span is not due to breakage so much as it is to the tree's susceptibility to heart-rot especially when branch crotches form and get older. Other problems include canker, verticillium wilt and root rot. Most redbud varieties thrive in full sun to partial shade. They will tolerate full shade but become elongated and thin as they reach for the sun. Redbuds do well in most soil types but adequate drainage is a must; it can tolerate dry shade of Eastern Kansas forests receiving at least 35" of rainfall per year. The species is a native from southern Canada to Florida, east to Kansas. The regular species also has the potential to self seed in your yard but not Burgundy Hearts. As a dwarf tree, use 'Merlot' as a specimen or part of a group. It reaches about 20 to 30 feet high and wide in full sun. Reddish leaf color emerges in the spring and is maintained all summer long if in mostly full sun. The color of older purple redbuds (like Forest Pansy) fades to dark green as the summer heat intensifies.
Don Egolf Redbud (Cercis canadensis 'Don Egolf') is a dwarf flowering shrub redbud native to China. It has the typical heart shaped green Redbud foliage and deep magenta flowers. The bark is more of a beige or light tan color with black buds. Flowering begins in April with flower buds starting on old wood all the way to the ground level. Flowering even occurs on very young plants only several inches tall. Because this is a Chinese species, no seed pods form like on native Redbuds. After many years, heights of 8 to 10 feet may be achieved on multi-stemmed plants. Culture conditions are pretty easy; just provide average garden soil, reasonable water, and mostly sun. In Eastern Kansas, typically our 40 inches of rainfall is sufficient without extra water if planted in good soils. Don Eagles Red has been growing in our display garden for over 10 years blooming consistently with no problems. It survived -16 degrees F and a week of single digit highs in February, 2021 with no damage to flower buds.
This purple-leaf Redbud (Cercis canadensis 'Merlot') is a canadensis and texensis cross to produce a more drought and heat tolerant tree.

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.
Ceropegia woodii known as the Rosary Vine and String of Hearts. This unusual, hardy vining succulent produces pretty, variegated, heart-shaped leaves with purple undersides on tough, wire-like stems. They are usually grown as a patio or house plant in Kansas. String of Hearts also grow well in hanging baskets as a durable, succulent plant able to survive drying out, heat and dry air like few others! If conditions get too rough, the foliage simply dies back and growth returns from underground tubers when favorable conditions return.

Gold Mop False Cypress (Chamaecyparis pisifera 'Gold Mop') is from a group of small coniferous shrubs from Asia with Juniper-like foliage. The foliage is bright yellow, thread-like and creates a relatively low, semi-weeping habit. It provides consistent color during spring, summer, fall, and darkens to a more gold color by winter providing excellent color when most other plants are dormant. Full sun and average garden conditions are preferred. Maintenance is pretty easy, only prune when needed to control size. Do not prune in late summer or fall. Coloring is definitely best if the plant can receive winter sun. Combine in the summer with other flowering perennials and shrubs. Combine in the winter with ornamental grasses, yuccas, Nandinas, or winter interest plants that contrast with gold.
Northern / Inland Sea Oats (Chasmanthium latifolium) is a grass native to the central and eastern United States including some areas in the southwest. Sea Oats is grown is notable for its large graceful seedheads and ability to tolerate full shade. Sending up blue-green spools of basal leaves in spring, it will grow to 2 feet tall with green seed heads starting to form earlier than most other grasses. As it turns a vivid green by June, the translucent green seedheads swaying in the breeze. By mid-summer, the seeds will have turned an attractive ivory and will turn brown in a few months before dropping off in fall. It looks attractive into late fall but becomes tattered after seeds drop making it a good grass to cut back in the late fall or early winter instead of Spring. For the home garden in rich well irrigated areas, this species can be too aggressive from self-seeding to mix with other plants. Use as a mass planting in any shaded area allowing extra room. However, in a difficult dry-shade garden, it will thrive, flower, and be relatively tame without much spread. Mulch will also stop self-seeding. It is one of the few plants that can survive under an established Silver Maple! Now if you need a plant to prevent soil erosion along streams, use this reseeding to your advantage! As it reseeds easily and can expand aggressively within a couple of years, it makes a solid root mat in moist erosion-prone loam soils.

Desert Willow is a small open irregularly branched tree or large shrub with bright green narrow leaves (but not related to true willows) It features gorgeous pink, white and magenta snapdragon-like flowers with yellow throats. Blooming season is immensely long beginning in June continuing all summer until frost. Desert Willow grows in all soil types here in Kansas but prefers rich silty loam. It will not grow in excessively wet anaerobic soils though. Absolute full sun is needed for best growth to produce flowers and avoid spindlyness. In the landscape, Desert Willow can be used as a specimen shrub or small tree. It handles hot west for south locations very well. It's native range covers most of the Southwest and western Texas along streams and riparian areas. Being surprisingly cold hardy here, Several Desert Willow cultivars can be found at the Denver Botanic Gardens in Denver CO (zone 5b) and at the Dyck Arboretum in Hesston, Kansas (zone 6b). Bubba Desert Willow (Chilopsis linearis 'Bubba') has been thriving in our display garden and other Lawrence, KS locations for over 15 years and has endured temperatures as low as a -18. During the most severe winters, winter kills it down to the ground. However, just like Crapemyrtle or Butterfly Bush, Desert Willow blooms on new wood and at a young age with blooms even occurring on 3 foot tall nursery plants. Water sprout regrowth from established landscape plants is rapid with heights reaching 5-6'. These blooms are more numerous and larger than normal, especially with a handful of time-release fertilized applied in the early spring.

Bubba Magenta Desert Willow (Chilopsis linearis 'Bubba') is a vigorous, fast-growing upright selection of desert willow that originated in Texas. Compared to other selections it has a strong vertical form and is less shrubby. It also has glossy, darker green, more lush foliage than other desert willows.
Fringe Tree, is also known as Chionanthus virginicus
Milky Way Spider Plant (Tropical), is also known as Chlorophytum comosum 'Milky Way'
Arctic Frost Hardy Satsuma (Citrus reticulata 'Arctic Frost') is typically grown in warmer zones as far North as Dallas (Zone 8a). Along with other tropicals and succulents in Kansas, Arctic Frost is usually grown as summer patio plant and then moved inside for the winter. Move to bright area in a cold garage, basement, or window over the winter with monthly watering. During the growing season, water regularly and place in full sun. If grown in a larger 20 gallon pot or so, it may flower and fruit when 4-5 feet tall after a few years. Before hard freezes come in the fall, move inside to protect from temperatures below 25 degrees F if you want fruit. Flower buds form in the winter on citrus trees. If you want evergreen foliage, protect with anything lower than 15 degrees F. It will tolerate down to 10 degrees F with complete defoliation and around 0 degrees F with complete wood kill down to the base of the trunk. Because it is grown on its own root system, it will come back true from winter kill down to the ground. A plant in our Lawrence, KS cold frame survived 0 degrees F for a few days and grew 3-4' back the following year. Don't expect flowers and fruit in these conditions though.
