Gardeners' Notes:

Positive palmbob On Apr 7, 2006, palmbob from Acton, CA (Zone 8b) wrote:

THere are many varieties of Euphorbia horrida, from nearly spineless to covered with long, intense spines- this form is the spiniest form and actually has been named... but it is still the same species of Euphorbia as all the other forms. It is generally a pale green to grey bodied plant, suckering/offsetting prolifically and will sometimes have tiny leaves near the top at the site of new growth in later winter/early spring but is otherwise leafless. All Euphorbia horridas originate from S Africa.
