Tephrocactus are cacti with rounded or geometric segments and varied spines, offering unusual silhouettes that distinguish each form in a collection.
Tephrocactus have stems made up of distinct segments, often rounded or geometric. Differences in the spines and arrangement of the segments make each form interesting for collections that value unusual silhouettes.
Some segments detach easily, so repotting and transport require care. As with other segmented cacti, glochids may be present, making hand protection necessary even when the larger spines look relatively harmless. Explore the plants in the category Opuntia.
