The Cactus Lactea (Euphorbia lactea) is a striking and highly decorative succulent shrub, often prized for its sculptural form and ghostly coloration. Despite its common name, this plant is not a true cactus but rather a member of the Euphorbia family. Its triangular, ridged stems are typically green with mottled white or creamy variegation, sometimes tinged with pink or purple under bright light. The upright, branching structure gives it a bold architectural presence, making it a favorite statement piece in modern plant collections.
Native to India and Sri Lanka, Euphorbia lactea thrives in warm, arid conditions and requires well-draining soil with minimal watering. Like most Euphorbias, it is drought tolerant and should be watered sparingly—allowing the soil to dry between waterings. It grows best in bright, indirect light or partial sun, and with the right care, it can reach impressive heights, making it suitable both as a container plant and for outdoor landscapes in warmer climates.
Because of its unusual form and coloration, the Cactus Lactea is often grafted onto sturdier Euphorbia rootstocks to create fascinating crested and fan-shaped specimens. These grafted varieties are especially popular with collectors seeking rare and exotic plants for display.
