Recommended Uses: Specimen plant in casual settings. Also useful as a natural screen or buffer plant. The fruits can provide a white haze for several weeks in the fall. The primary horticultural feature is the silvery, plume-like achenes which appear in the fall on female plants.
Considerations: Weak wood. Seed is wind disbursed and may become weedy.
Propagation: Seed. Salt bush is dioecious, that is, both a male and female plant are necessary for seed production - the photos at left show both the male (cream to yellow) and female (cream) flowers. The female flowers rapidly mature into bright, white tufted fruits making the plant showy for several weeks.
