Species:horrida

Family:Euphorbiaceae

The 'Nova' African Milk Barrel is a unique succulent shrub characterized by its spiny, irregularly clumping stems that display a striking combination of colors and wavy spines. This columnar plant features sharp ridges adorned with thorns and may exhibit white and green stripes along its stem. Over time, it develops into clusters, giving it a resemblance to barrel cacti, despite being from a different family.

During the summer, 'Nova' can thrive outdoors but should be brought inside before frost sets in. It requires bright sunlight, excellent drainage, and minimal watering to avoid rot. For optimal growth, plant it in containers with ample drainage holes and use soil specifically designed for succulents and cacti, ensuring to water thoroughly between dry spells. This species is known for being easy to cultivate.

Caution is advised when handling, as the milky sap of euphorbia can cause skin irritation; therefore, wearing gloves is recommended.
