Burrobush (Dumosa)

The Burrobush (Dumosa) is generally described as a perennial subshrub or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The greatest bloom is usually observed in the late winter, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Burrobush (Dumosa) has a short life span relative to most other plant species and a rapid growth rate. At maturity, the typical Burrobush (Dumosa) will reach up to 2 feet high, with a maximum height at 20 years of 2 feet.

The Burrobush (Dumosa) generally appears in field collections and doesn't tend to be commercially available. It can be propagated by bare root, container, seed. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -11°F. has high tolerance to drought and restricted water conditions.
