The Desertbroom (Sarothroides) is generally described as a perennial shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The Desertbroom (Sarothroides) has green foliage and inconspicuous yellow flowers, with an abuncance of conspicuous white fruits or seeds. The greatest bloom is usually observed in the late winter, with fruit and seed production starting in the spring and continuing until summer. Leaves are retained year to year. The Desertbroom (Sarothroides) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical Desertbroom (Sarothroides) will reach up to 12 feet high, with a maximum height at 20 years of 12 feet.

The Desertbroom (Sarothroides) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a rapid ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 28°F. has high tolerance to drought and restricted water conditions.
