Description
Euphorbia inermis var. huttonae is a form of Euphorbia inermis differing only by the flower character. Unlike E. inermis, which has green with white or pure white nectar-glands variably bifid on the outer margin with more or less long processes, this plant has yellow-green nectar-glands margins, truncate and toothed or more or less entire without processes. However, the most marked difference is in the densely hairy lobes between the glands of E. inermis and the glabrous lobes of E. inermis var. huttonae.
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. If you are growing them in containers or your soil is poor, feed with a half-strength fertilizer monthly.
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.
