Euphorbia characias
wulfenii has red stems and a profusion of chartreuse flowers. The
flowers start blooming in the middle of winter and continue through to the
middle of Fall. One of my clients calls Euphorbia characias wulfenii
the Martian. With those lime green flowers Mediterranean Spurge
does look it might have could have come from another planet. Euphorbia
characias seedlings are
common, sometimes too much so. This Euphorbia will rarely live
beyond the second season, but due to the numerous aforementioned progeny
this is rarely a problem. Care should be taken when working with the
Mediterranean Spurge because the milky sap is toxic and can burn the skin.
I use gloves or pick up the cut bits with my pruning shears.
