a few months ago i purchased some christmas cactus' being clearanced out at a local store and have no idea what color they might be. As I have repotted them and the new sprouts have started ,out of the 4, 2 are bight green new growth, one is purple, and one is kind of yellow tinted. does this kind of indicate what colors they will bloom? I have one already and all the growths it has put off are purple and all my blooms are a deep pink.
