Description
Euphorbia succulenta, formerly known as Monadenium succulentum, is a succulent plant with large fleshy rootstock, numerous dark green branches, and leaves produced at the growing point. It branches mostly from the base forming a domed cushion up to 2 feet (60 cm) in diameter. Leaves are fleshy and shot through with purple-pink streaks through the light green background. They last only one season. Flowers have a bract cup that is white or light pink. They are small but interesting and showy when produced in large numbers. This species is variable. There is considerable variability in the diameter of the stems, number and size of tubercles, the shape of leaves, and the length of inflorescences.

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. 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.
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.
