Gardeners' Notes:

Positive boomboer On Mar 9, 2011, boomboer from Cape Town

All of the "Snow Flake" sold in the trade in the States comes from a single plant in the Eastern Cape province of South Africa. More of the plants of this naturally occuring form have since been discovered, but it has a very limited distribution, only growing on three farms in the area. A beautiful plant.

I just bought one of these plants at H.D. The label had a interesting tidbit in that it said that only one "Snowflake" was ever found in Africa and from that single plant....

Here in California this is an extremely common and popular plant... almost all Targets and Home Depots sell this plant for just a few $$. It is a slow plant, however, and best grown in very well draining soil and bright light... plants growing in shade tend to rot if watered too much, especially if watered excessively in summer. This form of Euphorbia polygona is rarely spined... looks more like a white Euphorbia anoplia, in fact. Also does not get as fat as the non-white forms of E polygona. Still, it is quite frost resistant, with no damage I've noted when plants have been exposed down to 22F.
