Debra, We just bought these this spring.Stark Brothers. They stay upright and slim with apples forming around the trunk.DD grew them at her old house.
They are so neat in spring when they bloom.
DD didnt have any luck with columner apricots and apples in tubs.I think they froze in the winter here.
Let me know if you have any luck with them.
I see the last zone listed is 8
These are not the variety we planted
