I live in Anderson California and I had blooms end of May most of June. It experienced low temperatures in the teens and I may have lost it. I brought it in to the house, we will see.

This plant is listed as a zone 11, yet in zone 9b it has survived outdoors in the ground in my garden for 4-5 years, surviving numerous frosts with minimal damage, so I think that 11 zone is WAY OFF. I am not saying 9b is a great zone for it... maybe 10a or higher would be ideal. It doesn't seem to love being blasted by the sun in the summer and looks a bit blanched at times, but so far the winters have been nice to it. It is a bizzare Euphorbia for sure and has some really unusual thick, wrinkled leaves. So far mine hasn't flowered well, so perhaps this is a zone problems. This is a Madagascar native.
