Humulus lupulus. This dwarf variety is a good choice for small gardens where space is limited as it will only grow to a height of around 2-3 metres. Plant it on a trellis or other support where it will happily climb. The leaves start green, turning more yellow as the season progresses. It produces medium to large cones, with a fabulous aroma, that are used in brewing to produce a light bitter ale. A herbaceous perennial.
