Forgot to say earlier... as soon as I saw the title of the article, I started singing that Dinah Shore song. What little bit I know of it, anyway.
Sharon, I also have a burgundy foliage crabapple that I planted in my side yard, for the birds. And an ornamental Japanese crab apple that seemed like a good idea when I impulsively grabbed it at the store. So far, my burgundy guy has only had leaves, but he's only been out there 3 years. I didn't think of pollination when I planted it, but there IS a crab apple in a neighbor's yard across the street, so I would hope between it and my 2 other apple trees, it can get pollinated. Not sure I've seen flowers on it yet, honestly.
