This is my first year overwintering a few things in the garage,(azaleas, and a beauty berry), and so far so good,I think. If I am successful with them, I am going to take a step out of the tropical/subtropical box, but stay with flowering. Any thoughts or suggestions on something not terribly challenging? Things I have been considering are Japanese Quince, Pyracantha, Flowering Crab apples, and Crepe Myrtles. Winters here, are a crapshoot. Some years they are mild, but this year we had an extended period of single digit weather, when I had to move stuff from the garage to the attic. So, it's variable year, to year.
