Euphorbia ferox is a branching succulent shrublet adorned with delightful pink & lavender spines. Tiny ephemeral leaves emerge at the new growth. It's not a cactus, but you treat it like one: offering a minimum of 4-6 hours of direct sun & providing a period of drought between watering. In coldest period of winter, make sure you're allowing your plant to dry completely between watering.
Heads up: Euphorbia are not a pet friendly plant. 🐱🐶
