I have never seen it, but supposedly it is common in western Washington.
Wild Hops?
Several years ago we dug prohibition survivor hops from a road cut. Had to plant them in several places over a couple years. They eventually grew over a window trellis, probably 25 ft long and produced hops and made a lovely shade for West facing windows. My son made beer from them and IT WAS WONDERFULLY SMOOTH AND FLAVORFUL. Don’t know the variety...but was plentifully planted in the area before prohibition made people pull out their plants.
I will have to move it again this year.
