Description
Euphorbia trigona 'Royal Red', also known as Euphorbia trigona f. rubra, is an attractive succulent with stems and leaves flushed red to magenta. The stems are often greener for a lovely bi-colored look. They have 3 to 4 ridges and V-shaped lighter patterns. The reddish-brown spines are arranged in pairs on the ridges and can measure up to 0.2 inches (5 mm) in length. The leaves grow between the two spines on each ridge.
Hardiness
USDA hardiness zones 10a to 11b: from 30°F (-1.1°C) to 50°F (10°C).
How to Grow and Care
Euphorbias are very easy to care for. These plants require a little pampering to become established, but once they are, they are self-sufficient. More die from overcare and watering than from neglect. Euphorbias need well-draining soil and ample sunlight. They are not particular about soil pH but cannot tolerate wet soil. Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. Water whenever the top several inches are dry. Water deeply, but avoid letting them sit in wet soil, as this can cause root rot. Add some organic matter or fertilizer to the planting hole. Feed with a half-strength fertilizer monthly if you are growing them in containers or your soil is poor.
These succulents can be grown from seed, but they can be difficult to germinate (or even find). They are usually propagated by cuttings, which can be tricky because of the exuding sap. A rooting hormone is recommended for Euphorbias. They tend to grow problem-free, but there are a few pests and diseases to be alert for.
