Someone brought in this plant which they referred to as a Crown of Thorns. It is clearly a Euphorbia but not E. milii. There are no thorns, but some fuzzy growth along the ribs of the stem, which is four sided, the leaves are appr. 5 inches in length, and the petioles are a bright red.
I know there are appr. a zillion Euphorbias out there but I thought I'd toss it out there....
in advance!
