Check out the Common Blackberries (Rubus allegheniensis) I've been enjoying. Don't be jealous, go forage some before they are all gone!
For tips on picking the fruit of this sharp-spined plant, read Thag's post titled Instructions for picking wild blackberries.
While walking the roads of Plainville this week, I encountered several patches of Blue Huckleberries (Gaylussacia frondosa). They resemble wild blueberries, but they have crunchy seeds (ten to be exact) and a flavor all their own.
Black Huckleberry is similar, but different. Here is a photo comparing fruit clusters of each.
Here's a sneak peak at what is ripening on the landscape. I'll write a post on each of these plants when I harvest them. I have enjoyed some Common Blackberries already, but the majority of the crop is not yet mature.
