Treehugger,
I own many Euphorbias. Some in my yard hardy to zone 5 and lots inside my house. I must admit, I never saw anything close. I do like it. Does it have the white latex sap? Also I see you live close to me. I go to Janoski's Farm and Greenhouse often. Shame they shut down their green house during winter. Good farm store to go to.
