Check out Pink Lady apples from the supermarket in late spring for sprouted seeds in the core. You can use the apple seedlings from these as standard apple root stock or to experiment with seedling apple trees. You never know what quality of apple you'll get with open pollenated apples, but the Pink Lady apple usually is already sprouted after such a long time in cold storage. I've seen several seeds with roots and one with tiny leaves already this year in Pink Lady apples

But, you could always graft a proven apple to them. I just thought it was neat to find the fully sprouted apple tree seedling inside the apple I bought at the store. The kids got a kick out of it too.
