Artemisia arbuscula ssp. arbuscula
Habit: described as dwarf sagebrush, this aromatic perennial sub-shrub grows as a small mound with many branches. It is an evergreen shrub of irregular form generally growing only 4-16 in (10-40 cm) high with a crown spread of 16-32 in (40-80cm). The grayish-green leaves are spatula shaped and lobed at the tip. Leaves persist through winter and up to mid-season the following year; leaves from the previous year are shed during moisture stress. Small white flowers appear on spikes. The fibrous portion of the root system is shallow and fairly extensive, which allows for good water absorption.
Ecology: found particularly in arid regions, dry windy mesas, and open ridges of Eastern Oregon and Washington. The elevation range of dwarf sagebrush is from 2,300-11,500 ft (700-3500 m). Dwarf sagebrush sites are characterized by large amounts of bare ground and exposed surface rock.
Growing Conditions: full sun, can tolerate any soil type, preferring something more dry and rocky; high drought and cold tolerance.
It’s extensive fibrous root system and can be used to combat soil erosion. Dwarf sagebrush has some value for nesting, roosting, and resting sites for small birds and mammals as well as cover for escape.
