Desert Carpet, or Acacia Redolens, is a dense, small to medium-sized shrub that usually reaches 1.5 to 2 feet high.
Vegetative parts of the plant and especially the yellow flowers give off an intense vanilla scent. The spreading fragrant shrub can spread 8 to 10 feet wide. It blooms from August to October in its native range, and produces yellow puffball flowers that bloom from February through May (late winter to late spring). Some mounding occurs at the crown. It is recommended to remove vertical growth shoots as they occur. The Desert Carpet provides rapid coverage on slopes and is good for erosion control. It is found throughout Southern California and in some parts of the Bay Area.
