Cleistocactus




Cleistocactus strausii in my garden

     From Argentina, Ecuador and Paraguay, Cleistocactus is a genus of columnar cacti containing between 50 and 100 species. Usually slender, sometimes branching, the stems are covered with gold or white finely spaced spines giving these cacti a very attractive fuzzy look. Some like C. Strausii are erect and can reach a height of 10 feet. others such as C. winteri are pendant and sprawling.
     The name Cleistocactus comes from the Greek "kleistos", meaning closed, for the flowers which don't open all the way. During the growing season Cleistocactus can produce a profusion of colorfull flowers born along the side of the stem. Cleistocactus are fast growing in pot or garden and like a lot of water and fertilizer and light shade to full sun. The mix should be fast draining and a lot less water should be given in winter to prevent rot. They can be propagated by seeds or cuttings.
