I had the same thing happen to me. I thought maybe the seedsman got a few seeds mioxed up. The plant was healthy and green. Kept waiting and waiting for it to color but it remained green. I thought to myself why in the world would anyone want a flower with green petals let alone a seed company trying to sell such a thing. Well I riped it out after nursing it from a seedling. Glad to find out it was a disease and not a variety.
