About
Japanese Hops
Japanese hops is a climbing annual, herbaceous vine that grows up to 8’. Downward-pointing rough hairs on stems and leaves aid in twining clockwise on nearby vegetation. Stems are light green to reddish in color. It invades floodplains, stream banks and lakeshores, where seeds can disperse via water and vines can grow over vegetation. When working with this plant, blisters and dermatitis can occur.
