Humulus lupulus

Bloom Color: Green, Yellow. Main Bloom Time: Early fall, Late summer, Mid summer. Form: Spreading or horizontal, Variable spread.

Humulus lupulus is a PERENNIAL CLIMBER growing to 6 m at a medium rate.
It is hardy to zone 5 and is not frost tender. It is in flower from July to August, and the seeds ripen from September to October. The species is dioecious . and is pollinated by Wind. The plant is not self-fertile.
It is noted for attracting wildlife.
Suitable for: light , medium and heavy soils. Suitable pH: acid, neutral and basic soils. It can grow in semi-shade or no shade. It prefers dry or moist soil and can tolerate drought.

Landscape Uses:Ground cover, Screen. Easily grown in a good garden soil in sun or semi-shade. Prefers a deep rich loam and a warm sheltered position. Plants can succeed in dry shade if plenty of humus is incorporated into the soil, once established they are also somewhat drought tolerant. Hops are reported to tolerate an annual precipitation of between 31 and 137cm, an annual temperature in the range of 5.6 to 21.3°C and a pH of 4.5 to 8.2. Plants are very hardy tolerating temperatures down to about -20°c when dormant. The young shoots in spring, however, can be damaged by any more than a mild frost. A climbing plant, supporting itself by twining around the branches of other plants. Hops are frequently cultivated, both commercially and on a domestic scale, in temperate zones for their seed heads which have many medicinal qualities and are also used as a flavouring and preservative in beer. There are many named varieties. They grow best between the latitudes of 35 - 51°N and 34 - 43°S, with mean summer temperatures of 16 - 18°C. Generally, for beer making, the unfertilized seed heads are preferred and so most male plants are weeded out. Hops are fairly deep rooted, but with a network of shallow feeding roots. These horizontal feeding roots spread out at depth of 20 - 30 cm in the soil and give rise to fibrous roots in upper layers of soil. The vertical roots develop downwards to a depth of about 150 cm with a spread of 183 - 244 cm and have no fibrous roots. The bruised leaves are refreshingly aromatic whilst the flowers cast a pleasing scent. A food plant for many caterpillars. Dioecious. Male and female plants must be grown if seed is required. Special Features:
Edible, Invasive, Naturalizing, Attracts butterflies, Suitable for dried flowers, Inconspicuous flowers or blooms. The plant is heat tolerant in zones 8 through 1. .
At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 to 12 .
For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture information on the habit and root pattern is also useful and given here if available. Growth habit is a single or multiple shooting vine from a crown . Herbaceous. The root pattern is rhizomatous with underground stems sending roots and shoots along their length .
