Euphorbia Guillauminiana
AdvancedEuphorbia guillauminiana
A Madagascar Euphorbia with zebra-patterned trunk, rare and highly popular.
About
Euphorbia guillaumiana is a rare Malagasy endemic distinguished by the striking zebra-like striped patterning on its cylindrical trunk—a feature unique within the genus and the primary source of its high collector value. The trunk swells into a cylindrical caudex, and the bold horizontal banding is ornamental in its own right. Growth is slow and specimens are extremely difficult to obtain, commanding premium prices. Leaves are small and the flowers are typical small yellowish-green euphorbia cyathia. Damaged tissue exudes toxic white latex. Full sun to bright indirect light, extremely porous soil, restrained watering during growth, and complete winter drought are required. The unique zebra patterning and extreme rarity place this species among the most coveted euphorbias in the caudex world.

Growing Tips
Light & Placement
Grow in full sun to bright indirect light. A bright, airy spot keeps the trunk compact and brings out the striped pattern.
Watering
Water sparingly as a rule, only after the soil is completely dry. It is very sensitive to wet soil, so withhold water in winter and keep the trunk dry.
Temperature & Overwintering
Very sensitive to cold and wet; overwinter indoors above 10°C. Keep it in a warm, dry, bright spot and shield it from cold snaps.
Soil & Repotting
An extremely fast-draining mix prevents root rot. Growth is slow, so repotting only when root-bound, at the start of the growing season, is enough.
Pests & Cautions
Cut surfaces exude a toxic white latex. Wear gloves when handling and keep the latex off skin and eyes.
