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!

Cheers,
Sue

My guess is greenbrier. Although I now live in Missouri, I grew up in
West Virginia (about 50 mi. from the PA border) and this greenbrier,
which is a dead ringer for what you describe, was very common in
fields and waste areas. I can't speak whether it is an annual or not,
but the leaves, prickles and vining habit are characteristic.
