Growing Resin Spurge: A Complete Guide to This Fascinating Moroccan Succulent
I bought a resin spurge cactus because the thick, four-angled stems looked like something from a sci-fi movie. It was labeled as Euphorbia resinifera, and it has since formed a dense cluster that is pushing against the edge of its pot.
Why You’ll Love This Plant
Let me tell you, if you’re looking for a conversation starter in your garden, Resin Spurge is your guy! It’s that plant that makes everyone ask, “Is that a cactus?” (Spoiler: it’s not!)

Resin spurge needs full sun and soil that drains within seconds. Water deeply but rarely, and be careful of the milky sap when handling, since it irritates skin.
The “Wait, That’s Not a Cactus?” Moment
I remember my first encounter with Resin Spurge at a local nursery. Those four-sided, bluish-green stems had me fooled too! But this Moroccan native is actually a succulent with some serious attitude.
