Himalayan blackberry plant invasive bush

Himalayan blackberry (Rubus armeniacus) is one of the most aggressive invasive plants in the Pacific Northwest and across much of the United States. Arching canes reach 15 feet or more and root wherever they touch the ground, outcompeting native plants rapidly. It tolerates full sun to part shade and dry to moist soils, which is why it spreads so effectively in western Washington. For most gardeners and land stewards in this region the work is removal rather than planting.

Cultivated thornless blackberry varieties give the same summer harvest without the ecological cost. Contact PhyTu for a recommendation.
