Guide
The species-level account. Cultivar pages build on this and say where they differ.
Ferocactus wislizeni is a barrel cactus native to the arid deserts and dry grasslands of the southwestern United States and northern Mexico, so it stores water in its thick stem and rots if kept wet. Give it the brightest, sunniest spot you have and a gritty, fast-draining mineral mix. Water deeply only after the soil has been completely dry for a stretch — wait until the mix is bone dry several inches down, then water and let it dry out fully again.
