Cylindropuntia imbricata v. arborescens (Colorado Tree Cholla)
This hardy yet exotic looking cactus grows into a large shrub in time. Rosy-purple flowers appear in late spring once plants have grown to about 60 cm in height. A excellent landscape plant where it can grow to its full height, or it can also be grown in a large container. Be cautious with the spines!
