Mine went from cream to purple, no green. But I wonder if that really means anything. I mean, I got seeds for mine from a member on this site. I am certain they were open pollenated. I have no way of knowing if the plant is true, or not. For all I know, mine could be a cross and yours could be true. Or, perhaps both are true and there are two sub-varieties. Or perhaps you have a different, equally cool variety. It'll be fun to see what colors your pods go through.
