Etymology
The formal epithet "cristata" (pronounced "kris-TAY-tuh") means "tufted, crested, plumed."
Origin
Euphorbia lactea f. cristata is a form of Euphorbia lactea selected for its mutated growth. Euphorbia lactea is native to Sri Lanka but has become naturalized in tropical and subtropical regions worldwide.
Description
Euphorbia lactea f. cristata is a slow-growing succulent composed of fan-shaped branches arranged in an alternating undulating pattern. The branches are green and attractively marked with irregular, whitish or lime-green markings.
This popular crested form of Euphorbia lactea is often grown grafted onto the base of Euphorbia neriifolia.

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 overcare and watering than from neglect. Euphorbias need well-draining soil and ample 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 top several inches of the soil are dry. Water deeply, but avoid letting them sit in wet soil, as this 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.
