They Called It Crooked Back Cactus – What Is It?

Devils Backbone - Euphorbia tithymaloides

Ask the Expert: What is this “cactus”?
I purchased this plant at a flea market in SC and the seller called it a “Crooked Backed Cactus”. I haven’t been able to find this plant online under that name and would like to know what it is so that I can properly care for it. Melanie

Flower Shop Network Plant Expert Reply: Although the plant looked familiar, I could not place it. So I passed it on to Rick Pudwell at the Memphis Botanical Garden. I knew he would know exactly what the plant is called.

According to Rick

The plant is commonly called Devil’s Backbone. Botanical name is Euphorbia tithymaloides variegatus. It is a true succulent not a cactus. Like all Euphorbias the milky sap can cause a rash or irritation to exposed skin, so be careful if using it for cut material.

So there you have it! It is a Euphorbia tithymaloide.

Thanks Rick! You always come to my rescue.
