About This Species

Zone 4a BC Native

Grow me instead of Purple loosestrife

Hardhack is a native shrub ranging from 0.5 – 2.5 m in height, recognizable by its conical arrangements of densely packed pink flowers extending above branches covered with upright growing oval leaves in the summer. Hardhack is found growing in consistently moist soils such as swamps, bogs, and beside waterbodies like creeks and river. Bees love hardhack flowers, so this is a great species to plant to attract pollinators.

When selecting non-invasive plants for your garden, be sure to look for those that are suitable for your location, including moisture requirements, hardiness zone, and avoidance of known bear attractants among other factors.
