I am looking for a apple tree, The apple everybody calls a cooking apple or little green apples They are ready to pick at the end of june. I did have this tree where I lived before and they were green all over and tart.Do you know the name of this tree

It could have been an old variety that most people would call a June apple. Probably the closet you'll get at a tree nursery is one called "Lodi". Try Stark Brothers mail order catalog.
