For the last four years I have been getting everything off of trees on the lot my house is on. There is a large section by a creek that is unusable for housing, or anything else and out of it I have gotten winged elms, cherries, a pear, and others. Some of these are wild and some are volunteers from trees in the area.
Also, I have dug up a lot of former shrubs around the house. There are some fall blooming azaleas that have been blooming on the back porch and attracting hummingbirds and butterflies in swarms.
Also, there is a maple tree in the front yard that my oldest planted as a birthday present for my wife in about 1987 that has spectacular fall colors, and I have gathered a bunch of seedlings from it to turn into young bonsais as presents for the boys - a little piece of home. I have enough to make a small grove for us to take if we ever move out of the house.
I could go out looking other places, but I don't have space for what I have now, so there isn't much point in that.
