Euphorbia ambovombensis

Growth rate: It is a slow growing species and tubers take many years to enlarge.

Exposure: This plant has an excellent heat tolerance, and needs full sun to light shade exposures, but can tolerate shade. The color of this plant is much more marked if grown in full sun. But if it is possible to keep the growth of this species compact, with denser, shorter stems of a more uniform length (rather than looking weedy) such plants can be outright attractive.
Watering: Water regularly during the active growing season. No water should ever be allowed to stand around the roots. Keep almost completely dry in winter.
Hardiness: Tender. Keep the plant cooler in winter but maintain the light as bright as you can so that any growth which it may produce at this time will not be etiolated. It can be grown outdoors in the summer months to benefit from direct exposure to light, and especially exposure to high summer temperatures. Protection in a warm greenhouse in the middle of the winter will greatly increase the survival rate.
