Ok, feeling like an idiot, yes it's a wild berry, probably blackberry. It's small and sparse because it's in the deep woods. They're all over the place on the edges, tall, thick, brambly and full of blossoms. I just had never looked that closely at the blossoms. Moved in here last summer, never get the berries because the birds beat us to them.
Yes, we discovered several wild azaleas, light pink. And there's something in orange as well, has flowers more like honeysuckle though. Can't get close enough to tell if it's a vine around a dead sapling, or is itself a tall plant. Working on that.
