Friends of mine in Zone 5B bought this plant at a yard sale last year and don't remember what it was called. Seems to be coming back strong. I wasn't familiar with it. Can anyone help? Thanks.

There are quite a few species, varieties and hybrids of Euphorbia that will have similar flowers and decorative leaves. I do not know which ones will grow in your area. Check also if they reseed.
You might look into the many types of E. characias, E. amygdaloides, E. polychroma and many others, often just identified by variety.
