Cleistocactus: Home Care, Replanting And Propagation, Species

A genus like Cleistocactus (Cleistocactus) includes about 50 different plant species. In nature they can be found in South America, mostly in Uruguay. These cacti can be easily distinguished by their column-shaped, rather slender shoots which branch out at the base. On the surface of these stems there are a huge number of areoles, so the cactus itself is densely covered with white-yellow prickles.

This type of cactus can also be distinguished by its rather unusual flowers.

There are many scales on the surface of the tubular flowers. However, these flowers do not open in more cacti and this phenomenon is called cleistogamy (which has formed the name of the genus). Over time, the bud becomes similar to a rather long, brightly colored cone. Inside such a flower, seeds are formed as a result of self-pollination.
