This is native to the U.S. (United States) has its most active growth period in the spring and summer and fall . The greatest bloom is usually observed in the late summer, with fruit and seed production starting in the fall and continuing until winter. Leaves are not retained year to year. The Littleleaf Horsebrush (Glabrata) has a moderate life span relative to most other plant species and a slow growth rate. At maturity, the typical Littleleaf Horsebrush (Glabrata) will reach up to 12 feet high, with a maximum height at 20 years of 1 foot.

The Littleleaf Horsebrush (Glabrata) is not commonly available from nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, cuttings, seed. It has a moderate ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -13°F. has high tolerance to drought and restricted water conditions.
