Here is a view of the entire plant showing the umbrella shape; sorry I couldn't figure out how to add more than one pix per posting.
Assuming this was taken last year. Looks like Euphorbia corollata to me
Yes, you've got it, Lycopus.
It does appear to be Euphorbia corollata, thanks Lycopus. Sorry ken_adrian and others, it was taken last year in July; I am new to the hobby and took so many photos last year that I am still sorting through them to put them on my web site. Some of these plants showed the leaves spread out from the flower stalks and others seem to be drawn up tight to the stems; some had that distinctive umbrella look and in others it wasn't so obvious; some of the flowers had a bare looking center and others had distinctive stamen/pistils - confusing to a newbie - thanks again.
