My sister has gone "over the deep end" for dogwoods. For a few years now she has been collecting seeds and starting plants. (She's started several hundred to date). Her birthday is approaching, and it occurred to me that an unusual dogwood variety, or several, would be a great gift for her, but I don't know anything about them. She is Zone 7, lives in NE Arkansas. I've done a Google search and found several, but don't know anything about them, and thought some of you might have some ideas and sources for me.
