Humulus lupulus (common hop or hop) is a species of flowering plant in the Cannabaceae family, native to Europe, western Asia and North America. It is a dioecious, perennial, herbaceous climbing plant which sends up new shoots in early spring and dies back to a cold-hardy rhizome in autumn. Strictly speaking it is a bine rather than a vine, using its own shoots to act as supports for new growth.
