Description
Euphorbia cotinifolia is a tropical shrub usually under 10 feet (3 m) tall, but it can grow up to 18 feet (5.4 m) tall and be trained as a small tree. Stems are upright, purplish, and hold on long petioles the thin, slightly fleshy, ovate leaves with a beautiful deep burgundy color. The leaves are up to 4 inches (10 cm) long and up to 3 inches (7.5 cm) wide. Flowering occurs in late spring to mid-summer. While the tiny flowers at branch tips are not showy, the small cream to pale yellow bracts stand out attractively against the red foliage.

Hardiness
USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Euphorbias are very easy to care for. They require a little pampering to become established, but once they are, they are self-sufficient. In fact, more die from too much care and watering than from neglect. Euphorbias need well-draining soil and lots of sunlight. They are not particular about soil pH, but they 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 soil is dry several inches below the surface. Water deeply, but don't let them sit in wet soil, which 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.
Euphorbia can be grown from seed, but they can be difficult to germinate (or even find). It is usually propagated by cuttings. This can be tricky because of the exuding sap. Rooting hormone is recommended with Euphorbias. They tend to grow problem-free, but there are a few pests and diseases to be alert for.
