I cut back an unruly Hop (Humulus lupulus) in a neighbour's garden. Hops are vigorous climbers and scramblers in their natural habitats of woodland, hedgerow and scrubby open ground. Their climbing habit is used to good effect in row after row of hop poles in the hop fields of England.
H. lupulus is dioecious i.e. bears 'male' and 'female' flowers on different plants. The female catkins are the ones used for brewing. Decorative in a dangly sort of way; I saved a stem to hang from the mantlepiece.
