Ornamental Features

Willamette Hops is primarily grown for its highly ornamental fruit. It produces abundant clusters of light green hop-like fruit with yellow overtones from mid summer to mid fall. It attractive tomentose lobed leaves remain dark green in colour throughout the season.

Landscape Attributes

Willamette Hops is a dense herbaceous perennial vine with a twining and trailing habit of growth. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This is a high maintenance plant that will require regular care and upkeep, and can be pruned at anytime. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Insects
  • Disease

Willamette Hops is recommended for the following landscape applications;

  • Hedges/Screening
  • General Garden Use
  • Naturalizing And Woodland Gardens
  • Container Planting

Planting & Growing

Willamette Hops will grow to be about 25 feet tall at maturity, with a spread of 3 feet. As a climbing vine, it should either be planted near a fence, trellis or other landscape structure where it can be trained to grow upwards on it, or allowed to trail off a retaining wall or slope. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen! This is a self-pollinating variety, so it doesn't require a second plant nearby to set fruit.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Willamette Hops is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
