The Euphorbia cereiformis, known as milk barrel cactus, is a striking succulent known for its barrel-shaped stems and ribbed columnar growth. This plant is popular for its unusual appearance and low-maintenance care needs.  

Native to South Africa, this Euphorbia plant typically grows in clumps of upright, ribbed stems that resemble miniature cactus columns.

These stems are a gray-green to bluish-green color with prominent ridges lined with small, brownish spines (technically modified leaves).

Each stem can reach up to 3 feet tall, and as the plant matures, it slowly produces offsets, forming dense clumps that give the appearance of a barrel-like cluster.

The growth habit is symmetrical and highly architectural, making it an excellent accent plant. 

Among the Euphorbia varieties, Euphorbia horrida, opens in a new tab (African Milk Barrel), is one of the more popular choices. 

The Euphorbia cereiformis produces small yellow-green cyathia, near the top of its stems. These blooms are modest but still intriguing, especially when viewed up close. Flowering generally occurs in warm months under ideal conditions, including plenty of sunlight and minimal water stress. 

When it comes to care, it thrives in well-drained  succulent soil, opens in a new tab and prefers to be watered deeply but infrequently, only when the soil is completely dry.

Indoors, place it near a bright, sunny window where it receives 6–8 hours of indirect to direct light daily.

Outdoors, it does well in USDA zones 10–11, where temperatures rarely dip below 30°F.

Pruning is rarely needed, but you can remove dead stems or pups to maintain shape or propagate.

Overall, the Euphorbia cereiformis ‘Milk Barrel’ is a sculptural, easy-care plant that thrives with minimal attention and adds visual drama to succulent collections. Its cactus-like appearance, drought tolerance, and slow-clumping growth make it a favorite for collectors seeking architectural interest with little fuss. Whether indoors on a sunny windowsill or outdoors in a dry landscape, this Euphorbia delivers long-lasting appeal with minimal upkeep.
