Euphorbia caput-medusae is best grown from seed if you want the sprawling shape typical of the plant - from cuttings you tend to get an atypical upright growth form. A very nice Euphorbia - not fussy and with lovely fragrant flowers in spring.

THis is one of the more prolific medusoid Euphorbias, sometimes forming massive, sprawling matts of 'branches' twisting and trailing in all directions. However, it can also be a gorgeous plant if 'pruned' back now and then, or when grown in a pot. Takes full sun in southern California, but tends to look a bit bleached in hot summers.

In its native South Africa it lives on slopes near the sea that get more rainful than most other medudoid Euphorbias see, so this might be a good one to try in more humid areas that rot the other species.

I got this plant as a cutting in 1996. It spends the growing season outside in about 85% direct sun & is brought indoors before the 1st freeze & generally neglected until spring. It started blooming in 2000 & has flowered every year since. The flowers are bright yellow.
