Description

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. 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. Succulents are usually spineless and grown for their beautiful shapes, color and texture. Cacti are known for their spines, unusual shapes and beautiful flowers. Both succulents and cacti store water in their fleshy tissues. And can survive long periods without water. Cacti and succulents are usually grown as a deck/patio plant or house plant in Kansas. Grow in full sun with little to no extra watering except that which comes from rainfall. Generally, plants may be brought out in Late May through Early October in our zone 6a Lawrence, KS climate. To play is safe, potted plants are best moved in before autumn leaves begin to drop and before night temperatures get below 45 degrees F. It is very important to avoid the combination of wet and cold. Move to a bright interior window over the winter with little to no watering and keep above 50 degrees F. As a winter house plant, it will look presentable all winter long with little to no waterings. As a permanent house plant, provide bright light and allow the soil to dry completely between waterings and you will get many years of carefree enjoyment. Plants grown permanently indoors may eventually begin to elongate stretching for light and lose their spine color. It can be hard to reproduce the intense UV sunlight they need when growing indoors 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 may occur. 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 but avoid peat moss. The “soil” most commercial cacti are potted in to too peaty and light weight. This soil becomes hydrophobic and shrinks after becoming bone dry and difficult to re wet again. Cacti never grow in peat-based soils in nature; this “Soil” is only good for shipping because of the light weight. Potted plants are very low maintenance but watch for scale and mealybugs that may hide beneath the cover of spines. The best pest removal approach is to periodically wash the cactus off. Achieve this with a water nozzle or hose breaker turned mostly off to increase the pressure from the blast of water. This high-pressured water kills the pests without damaging the thick cactus skin. Here are some little-known or rare factoids about cacti: 1. The "spines" are actually modified leaves filled with sap at first, then quickly drying out to form the spines! 2. Many cacti have bright colored flowers that mainly attract bees, while some tubular flowering types attract hummingbirds and bats. 3. Late on the evolutionary timeline, cacti fossils are rare to non-existent. Cacti are native almost exclusively to the Americas, while succulents can include a much larger plant palette be from any dry area in the world. 4. Some cactus plants have been known to survive more than 2 years without water. 5. Some cacti first evolved in a dry climate that later became wetter again. For example: several jungle species live as epiphytes in trees to achieve the fast drainage they need.
