Mugwort (Artemisia douglasiana) is a fast growing shrub chosen primarily for its aromatic gray foliage which makes a year round contrast behind other plants. The beautiful, silver gray leaves add texture and color to the garden. It grows to 4 feet high by 5 feet wide and will spread by underground rhizomes, especially in moist areas.The flowers are small and inconspicuous, often not producing viable seed. 


It does best in the sun but will tolerate shade. As it is native to riverbeds and other moist places it is vigorous if given water, but will tolerate drier conditions.  Dead stems cut back in the winter will resprout in the spring.


Mugwort is sometimes grown for medicinal purposes. It is also useful in restoration projects and for erosion control.


Various insects are attracted to the flowers and it hosts a likely total of 28 species of butterfly and moth.
