Besser ex Besser
Artemisia heterophylla Besser
The plant prefers direct sunlight and moist soils, but tolerates shady areas and dry soils. It occupies hardiness zones 6a to 10b and occurs at elevations ranging from 0–3080 meters. A. douglasiana is often found in ditches and streambanks.
Artemisia douglasiana is dicot, and a perennial forb. Its stems grow from a substantial colony of rhizomes which require a minimum soil depth of 16 cm and can grow in fine to coarse soils. The stems grow erect and range in height from 0.5–2.5 metres (1.6–8.2 ft).
Its grey-green leaves are evenly spaced, elliptical, and lobed at the tips. The appearance of the 3–5 lobes at the tips of its leaves may range from being seemingly absent to being highly defined.
Although A. douglasiana can reproduce from seed, it's primarily propagated from division and spreading of its underground rhizomes. The extensive rhizomes help prevent erosion by stabilizing streambanks. A. douglasiana is susceptible to infection by Xylella fastidiosa which causes Pierce's disease.
Artemisia douglasiana was used by Native American tribes as a medicinal plant to relieve joint pain and headaches, and to treat abrasions and rashes (including poison ivy). It was also used to treat women's reproductive issues, including irregular menstruation and was occasionally used as an abortifacient.
Artemisia douglasiana is cultivated as an ornamental plant by specialty native plant nurseries, for planting in wildlife gardens, natural landscaping design, and habitat restoration and erosion control projects.
