Varieties of fastest growing fruit trees?
Looking for specific varieties of fastest-growing fruit trees for zone 6b. Time to fruit, and type of fruit is irrelevant.
My co-worker, who knows nothing about plants, has asked me to help her pick out a tree for her backyard. She is not picky, just as long as it "looks like a tree" and can handle periodic drought, as they do not have a water source in their backyard and she's not likely going to be a dedicated waterer.
My experience with fruit trees is limited to the established trees that I grew up with in San Diego, so I have little experience with young, cold-hardy varieties. I'm hoping to get recommendations for specific varieties of trees that my co-worker can plant and which will add instant greenery to her currently barren backyard.
I've been reading and it appears that peach, apples, and pears grow the fastest. I know that mulberry trees shoot up, but am hesitant to recommend them because of the mess the berries can make when they are ripe. Thoughts? Recommendations? Thanks!
