Can any of you suggest any trees that grow at a super fast rate for a 7a or 7b zone? We just bought a house and land, and while we have lots of trees, none are in a good area to create a nice shady garden near the house. I'm too old to buy small trees and wait for them to grow tall if they are slow growing, and I really don't want to buy huge trees since they cost too much for the most part. Any suggestions would be great. Oh, and no more pine trees. We have more than enough of those.
Edited to add that I don't need any more fruit trees either. We have a small orchard with very young trees, and there are more than enough of those.
