I haave grown bllue camassia for years, with wonderful success, now their buds are high and will soon open, but the white ones have never done anything. I do wonder if they are just a breeders 'sport' rahter than a colour the plant developed itself? Sometimes in their enthusiasm to give us something new, the resulting offerings aren't up to natures plans. I too have given up with th white ones, added to which, here at least, they did not come up and try to flower at the same time as the blue, which had been my, now bandoned, plan. Should have guessed nature would win, she usually does!
