Euphorbia enopla because it has longer red spines as coma red to its look-alike E. anoplia. On the right might be E. horrida. Both are very nice.

Thanks Howard
I don't know much at all about Euphorbias. Horrida must be variable. all the pics seem to only show the silver gray form. Most of the pictures don't give you an idea about size.

The "white" form is E. horrida 'Snowflake'

Google "Euphorbia horrida major"

I found a really neat site for ID'en Euphorbia. I am learning a lot on this site. Better than any book about them. Also most Cactus and Succulents. They are just beginning and need our help to fill in.

E. horrida takes up to 5 years to bloom so it may be another type. There are many horride hybrids.

Thanks for your info. This has helped me out quite a bit. I looked at the web site Greg and it is one I have been using for a while but didn't think of checking out Euphorbias on it.
