Douglas Aster, also known as Aster subspicatum, is a stunning perennial wildflower native to British Columbia. This hardy plant is found in various regions of the province and is also common in Washington and Oregon.

The leaves of the Douglas Aster are silvery and saw-toothed with fine, close, feltlike woolly hairs. The plant produces heads with ray and disk flowers that can be violet or yellow in colour. Achenes are faintly nerved, and the pappus is usually reddish at maturity. The Douglas Aster thrives in full sun in moist conditions and has moderate drought tolerance. Well-drained and moist soil is best for this plant, and it spreads slowly by underground rhizomes. Clumps can be split up and replanted every 2-3 years.

The Douglas Aster is an essential crop for nectar feeding in the fall and attracts many pollinators. In addition, Indigenous Peoples used aster species for various medicinal purposes, such as making tea from the roots to treat fevers and diarrhea, placing burned or powdered preparations in or on wounds, and making a tea from the whole plant and using an absorbent material to push it into the wound.

Bring a touch of the wild to your garden with the Douglas Aster, a beautiful and beneficial addition to any landscape.
