Mugwort (Artemisia douglasiana):
This hardy and aromatic shrub is a common plant found all throughout California. Though it produces flowers with seeds, the plant spreads through rhizomes, which is an underground spreading system that sends up shoots from its roots to produce new plants. You’ll find Mugwort growing at the Preserve along the trails, in moist, riparian areas. Miwok utilized this plant medicinally, as a relief for decongestion, headaches, and to relieve the effects of stinging nettle and poison oak on the skin.
