I'm in zone 6, PA. I'm trying to ID a vineing weed that is common along the
edges of woods and fields and is in some of my garden beds. I'm fairly sure
it's an annual. It's a thin vine with a very minimal root system that
climbs into trees and shrubs and grows very vigorously once established. It
has triangular alternate leaves, about 2 inches across, and unpleasant
small prickles all along the vine that break off in your skin. It clings to
shrubs with the prickles, and does not really twine around like bindweed. I
haven't let any go to seed this year, but I seem to recall it gets small
dark blue berries later in the season.
It's relatively easy to control by pulling (with gloves on!), I just want to
put a name to it. I've tried several on-line weed id sites and didn't come
up with it. Thanks for your consideration!
