Description
Euphorbia stellata is a small, geophytic succulent with tufted, prostrate, 2-ribbed branches that radiate on the top of a woody caudex. It is one of the species belonging to the Medusoid Euphorbia group. The caudex can reach a height of up to 6 inches (15 cm) and a diameter of 3 inches (7.5 cm). The branches are dark green with feathery whitish markings. They can grow up to 6 inches (15 cm) long and 0.6 inches (1.5 cm) wide. The margins of the branches are winged with sinuate teeth about 0.2 inches (6 mm) apart.
The flowers are greenish-yellow and appear in late spring and early summer.

How to Grow and Care for Euphorbia stellata
Hardiness: USDA hardiness zones 9b to 11b: from 25°F (-3.9°C) to 50°F (10°C).
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 of the soil 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. This can be tricky because of the exuding sap. Rooting hormone is recommended with Euphorbia. They tend to grow problem-free, but there are a few pests and diseases to be alert for.
