I'm going to be following this
thread with interest, since we have a similar situation, though a smaller space (1 acre). We have a little corner gully/drainage creek where the lindens have been dying. The honeysuckle were all the understory(?), and then mostly daylilies and some skunk cabbage, and others I'm not familiar with. As the lindens have been falling, it's been very nicely shaded, and I'm hoping to take out the honeysuckle and replace it with something, too. There are utility lines, so I'd like to keep it as something smaller. And it's a visible corner of our suburban lot, so I like the idea of the shrubs for a little privacy. I'd been looking at the american plum

The blue honeysuckle looks exciting, though, too, and it fits my concern about the height better.
CJ, did you order from Oikos?
