I've known that one of the NASC S. leucophyllas (Short Tube, Wide Mouth - AL005) I'm growing has little, if any, red pigment. Now I see that it is going to have a yellow flower. Can someone explain the criteria for deciding an S. leuc. is truly anthocyanin free? I saw something about it once, but can't remember where. Also, is anyone else growing one of these AL005 plants that has yellow flowers? By the way, the reason I've never been sure whether this plant has any red in it is that it is in a pot with three other AL005 plants and I can't see the base very well. I guess it's time to separate them.
