Euphorbia myrsinites is an attractive succulent with trailing stems rising at the tips and covered with spirals of closely set, waxy, bluish-green leaves. The stems are succulent, unbranched or branched, and grow up to 16 inches (40 cm) long. Leaves are fleshy, pointed, and up to 1.2 inches (3 cm) long and up to 0.7 inches (1.7 cm) wide. The nonshowy greenish flowers are subtended by showy yellow bracts that are sometimes suffused with pink, especially as they age. They appear in compact terminal clusters in spring. Fruits are subglobose capsules with brownish to grayish seeds.
USDA hardiness zones 5a to 9b: from −20 °F (−28.9 °C) to 30 °F (−1.1 °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 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 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. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly.
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 Euphorbias. They tend to grow problem-free, but there are a few pests and diseases to be alert for.
