About Northern Willow Herb

Northern Willow Herb (Epilobium glandulosum, often classified as E. ciliatum ssp. glandulosum) is a hardy and adaptable perennial that thrives in the cooler, moist regions of North America. Typically reaching heights of 1 to 3 feet, this plant features lance-shaped leaves and clusters of small, four-petaled flowers that range from pale pink to white, often with darker veins. Blooming from July into September, it provides a consistent nectar source for generalist pollinators like small bees and syrphid flies. After flowering, it produces slender seed pods filled with tiny seeds attached to brilliant white, silky tufts that are easily dispersed by the wind. This species is frequently found in moist meadows, along stream banks, and in disturbed wetland areas. It prefers full to partial sun and consistently moist to wet soils, though it is remarkably resilient in various conditions. Northern Willow Herb is an excellent addition to naturalized wetland plantings or restoration sites where a dependable, colonizing species is needed to support local biodiversity.
