These seedlings around 'Holy Mouse Ears' appeared in this spot last year. I didn't move them and they survived the winter. I should probably move the larger ones near HME but am wondering whether I can safely move the tiny yellow ones to another spot in the garden. What do you do with your seedlings?

I'm most interested in preserving the yellow ones as the hostas immediately surrounding them are "Blue Mouse Ears', 'Blue Dimples', 'Touch of Class', 'Dream Queen' and 'Salute'. The yellow seedlings were yellow last year and haven't changed. What are the chances of the yellow ones being a cross with one of the mice?
