Made about 70 seedlings last year, openly pollinated, mother an ornamental apple / crab apple. On of the plants have very different leaves, they are somewhat spiky and a lot broader compared to other seedlings and apple trees that I got.
Any wild guesses? What have caused this? Is it going to be a healthy tree only with odd leaves? Could it possibly help me guess how the fruits/tree will turn out? Are there any known apples with this type of leaves?
Picture from earlier this evening.
