Description
Euphorbia decaryi is a small, shrubby succulent with swollen roots and erect to creeping stems bearing attractive, fleshy leaves tufted in rosettes at the tips of the stems. It can grow up to 6 inches (15 cm) tall and spread by rhizomes. When exposed to intense sunlight, the green leaves take on a lovely coppery-bronze hue. They are highly undulated, folded, and with raised veins.
The unusual flowers are bell-shaped, range in color from yellow and yellow-green to reddish, and appear in summer.
Origin
Euphorbia decaryi is native to southeastern Madagascar.
Etymology

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. 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. 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.
