Thanks, Lonnit. I checked a few horticultural websites and you're right, they are definitely Pokeweed. I have changed the title accordingly. While making the image, I kept wishing they were a color other than green so I'd get more contrast between the berries and the background. Now that I know they turn blue, I'll go back when they're more "photogenic". -Philio Vance
I think they are the immature version of these:
