Left, a red delicious tree. Nearby is a yellow delicious. Their fruit is sweet and tasty, but small because the trees are not pruned as they would be in an actual orchard.
According to city arborist Jim Bower, the trees were part of a mixed group purchased from a nursery around 1998. The mix was to include small to mid-size trees such as crabapples that would fit in an urban setting. Somehow the red and yellow delicious trees got on the truck.
My family had a small orchard years ago, about a dozen trees -- peaches, pears, plums, sour cherries, and apples. When I first moved here and Dad visited and saw the trees, he immediately identified them.
When they get ripe I pick the apples, and make applesauce and baked desserts. Delicious!
