I have several yellow babies near my Dancing Queen that I'm leaving to see if they grow up to be something special. I don't get many yellow seedlings, so it's kinda fun to watch and hope for a nice one. Good luck with your find!
I think I'll just leave them where they are for now. I have one that I think is from Pee Dee Gold Flash that has been in the ground for 3 years, and it's staying pretty nice. I'll see if I can remember to get a picture of it.
