Description
The stems of Homalocephala polycephala are sometimes solitary, but more often in clusters of as many as 30, each up to 0.6 m tall. The spines are yellow to red. The fruits are densely woolly, giving the common name cotton top cactus. The tendency of the cactus to cluster causes it to also be called many-headed barrel cactus.[2]
They have a reputation for being difficult in cultivation, and are rarely seen in cactus collections.
