Dead Plant (Caudex)

Dead Plant (Caudex) (Euphorbia decaryi ‘caudex’)

• Other Known Names: Euphorbia decaryi ‘Caudex’, Madagascar Spine Plant
• Genus: Euphorbia
• Species: decaryi

Aesthetic Description

The Dead Plant (Caudex) looks like it wandered out of a desert apothecary. Its gnarled, woody base (caudex) supports wrinkled, narrow leaves that lie flat like twisted parchment, often tinged in purples, browns, or greens. It might look parched, but it’s alive — and that’s the point. This Euphorbia thrives on looking half-wilted, full of drama, and proud of its survivalist style.

Scientific Description

Euphorbia decaryi ‘caudex’ is a slow-growing succulent from the Euphorbiaceae family, endemic to Madagascar. This form is characterized by its caudex — a woody, swollen stem base that stores water. Leaves are narrow, curled, and irregularly textured, while small yellow-green cyathia (flowers) may appear seasonally. It uses CAM photosynthesis and is highly drought-adapted.

General Botanical Information

This Euphorbia is prized by collectors for its unusual habit and low-growing, gnarled form. It does well in bonsai-style pots or shallow dish gardens. Because it rarely changes dramatically, it’s a plant for patient eyes — those who enjoy a survivor’s beauty. Avoid overwatering and handle with care, as like all Euphorbias, it exudes a toxic sap.

• Watering: Infrequent; allow soil to fully dry
