Euphorbia pulvinata

Origin Euphorbia pulvinata is native to South Africa, with a broad distribution range across the Eastern Cape, KwaZulu-Natal, Free State, and Mpumalanga provinces. It also occurs in Lesotho. It was officially described by Marloth in 1909.

Habitat In the wild, this species thrives in stony areas and rocky outcrops, often on northern-facing slopes where it receives maximum sun exposure. It is frequently found in mountainous regions and grasslands, growing in well-drained, mineral-rich soil. It is a highly resilient species, capable of withstanding both intense summer heat and cold, frosty winters, as long as the conditions remain dry.

Description Euphorbia pulvinata is a low-growing, dioecious, succulent perennial known for its spectacular "cushion-forming" growth habit.

• Growth Habit: It forms extremely dense, compact rounded clumps (cushions) that can consist of hundreds of individual stems. In habitat, these clumps can grow up to 1 meter in diameter, resembling a green, spiny pillow.

• Stems: The stems are short, thick, and cylindrical (usually 2–5 cm in diameter).  The epidermis is a vibrant light green to bluish-green.

• Spines (Peduncles): The "spines" of this species are actually persistent sterile peduncles (flower stalks). They are sturdy, woody, and reddish-brown when young, turning gray with age. 

• Foliage: The leaves are minute, ephemeral, and only appear at the apex of growing stems during the rainy season, dropping off almost immediately.

• Flowers (Cyathia): As a dioecious species, male and female flowers are borne on separate plants. The cyathia are small, dark red to purplish, appearing at the tips of the stems in early spring.

• Cultivation: This is one of the hardier Euphorbias. It requires full sun to maintain its tight, mounded shape. It necessitates a porous mineral substrate and is relatively drought-tolerant. It can handle colder temperatures than many Madagascan species, provided the soil is kept bone-dry.
