Description

'Nova' African Milk Barrel is a spiny succulent shrub with irregular basally clumping stems with distinctive coloration and waviness of the spines. This columnar plant has sharp ridges lined with thorns. It can have stripes of white and green marking its stem. They will form clusters over time. The growth habit of this species makes it resemble the unrelated barrel cacti. 

'Nova' can be grown outdoors in summer and brought indoors before frost. They need bright sunlight, great drainage, and infrequent water to prevent rot. Grow in containers with many drainage holes and soil appropriate for succulents and cacti and water deeply between periods of dring out. Easy to grow.

The milky sap of euphorbia can irritate the skin so wear gloves to handle.
