I bought a Euphorbia milii or COT about a year and a half ago from a Buddhist Temple in Tampa. (They have a market every Sunday with Thai food and various plants) She used to have white flowers that were in constant bloom. I re-potted her a few months ago, about the end of June, because she was two big for the container she was in. (I still had her in the cheap flimsy plastic container she came in) She has a lot of healthy growth since and is even branching off in three places year the top. Prior, it was just 1 stem with the leaves and flowers near the top. Well now the flowers are not white, they're green... about the same color as the newly grown leaves. and only 1 bract with 5-6 flowers as opposed to 3-4 bracts with 5-6 flowers like she used to give. Does she have a problem or does this happen sometimes?

The only thing I've changed is the container. The location she is in is the same. She gets about 2-3 hours of morning sun, then shaded sun for about 7-8 hours. I water her the same. I wait until the top 2-2.5 inches of soil is dry and water close to the stem. She is in an un-glazed terracotta pot with very good drainage. The soil I used is a cactus blend that has peat moss, sand, and perlite. I also used some gavel at the bottom for extra drainage.

Can someone let me know what I need to do to restore her or if this is natural?
