The Purple Sage (Dorrii) 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 spring, with fruit and seed production starting in the spring and continuing until summer. Leaves are not retained year to year. The Purple Sage (Dorrii) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical Purple Sage (Dorrii) will reach up to 2.5 feet high, with a maximum height at 20 years of 2 feet.

The Purple Sage (Dorrii) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a moderate 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 -23°F. has medium tolerance to drought and restricted water conditions.
