The hop (Humulus) is a small genus of flowering plants, native to the temperate Northern Hemisphere. The female flowers, commonly called hops, are used as flavouring and stabilisers during beer brewing.

Although frequently referred to as the hop vine, it is technically a bine; unlike vines, which use tendrils, suckers, and other appendages for attaching themselves, bines have stout stems with stiff hairs to aid in climbing. It is a perennial herbaceous plant which sends up new shoots in early spring and dies back to the cold-hardy rhizome in autumn. Hop shoots grow very rapidly and at the peak of growth can grow 20-50 cm per week. Hop bines climb by wrapping clockwise around anything within reach, and individual bines typically grow between 2 to 15 m depending on what is available to grow on. The leaves are opposite, with a 7-12 cm petiole and a cordate-based, palmately lobed blade 12-25 cm long and broad; the edges are coarsely toothed. When the hop bines run out of material to climb, horizontal shoots sprout between the leaves of the main stem to form a network of stems wound round each other.
