Hi Chuck,
There are I think three seedlings left - in that picture - I had one or two others but they either "bloomed out" or were crowded out. I'll try to get a comparison close-up picture but you can probably see that the middle one has a rosey-violet color and seems to show some yellow in the background. The ones on either side are almost identical to each other.

Are all in first generation like this?
