Devil’s Backbone

Devil’s Backbone (Euphorbia tithymaloides variegata)

• Other Known Names: Redbird Cactus, Zigzag Plant, Slipper Flower
• Genus: Euphorbia
• Species: tithymaloides

Aesthetic Description

Devil’s Backbone earns its name with dramatic flair — upright stems twist in a zigzag pattern, stacked with fleshy, pointed leaves striped in green and cream. The stem alone looks like botanical lightning. When in bloom, it can produce tiny, slipper-shaped red flowers that add a surreal, almost cartoonish quality. This plant doesn’t just grow — it dances.

Scientific Description

Euphorbia tithymaloides variegata is a variegated form of a tropical succulent shrub in the Euphorbiaceae family, native to Central America and the Caribbean. It grows with alternately arranged, thick, fleshy leaves on wavy stems that branch irregularly. The plant produces small, red, cyathium-type flowers at the tips of stems. Like many Euphorbias, it contains a milky sap that can be irritating to skin and eyes.
