Landscape Use: Xeriscape, native gardens, Mojave Desert restoration projects, low growing and spreading filler plant, mass plantings, highway medium plantings
Form & Character: Evergreen herbaceous perennial, mounding, dense, rounded, regular
Growth Habit: Winter active, highly branched and dense, summer dormant and will become leafless during long periods without water, irrigation will increase size.
Foliage/Texture: Leaves are alternately arranged, ovate, pinntified, mostly evergreen, highly glaucous, very small, young stems densely pubescent (haired); fine texture
Flowers & Fruits: Small yellow flowers with staminate and pistallate heads on a single plant. Fruits bur-like and ranging in color from golden to purple to brown.

Watering: None needed after establishment. Occasional water during the winter may be applied if winter rains fail to materialize in order to invigorate. Responds well to supplemental water especially during the summer; however, too much extra water will encourage rank growth.
Pruning: Slight shearing during the fall before onset of winter growth is used to increase landscape symmetry.

Additional comments: White bursage is not a plant for use in mesic garden themes. It is best as a companion filler plant for native plantings and gardens.
