Genus Information: In North America there are 6 species and 6 accepted taxa overall for Ferocactus. Worldwide, The Plant List includes 24 accepted species names and a further 149 scientific names of infraspecific rank for the genus.

Comments: Candy Barrelcactus has a strong tendency to lean toward the south as adult and will often fall over pulling the roots out of the ground. Rotting plants play host to an entire ecosystem of insects and fungi. Another very large species of Barrel Cactus is Emory's Barrel Cactus, F. emoryi (covillei) which also blooms about the same time and has overlapping ranges.

To date there is little or no documentation to suggest that this species hybridizes with California Barrel Cactus, F. cylindraceus however there are claims in the literature for claiming hybridization between these two species as an answer to confusion between identification of species in areas of overlap.

Importance to Wildlife; Candy Barrel Cactus is eaten by Mule Deer, Javelina (sometimes called Collared Peccary) and livestock. Rabbits will eat the plants of the spines have been eliminated, especially through range fire. The seeds readily attract birds and small mammals.
