- Medicinal Plants - Rosemary
The rosemary (Rosmarinus officinalis) is generally described as a Perennial Subshrub or Shrub. This Dicot (dicotyledon) is not native to the U.S. (United States) and has its most active growth period in the Spring and Summer. The Rosemary has Dark Green foliage and conspicuous Blue flowers, with Brown fruits or seeds. The greatest bloom is usually observed in the Mid Spring, with fruit and seed production starting in the Spring and continuing until Summer. Leaves are retained year to year. The Rosemary has a long life span relative to most other plant species and a moderate growth rate. At maturity, the typical Rosemary will reach up to 5 feet high, with a maximum height at 20 years of 5 feet.
The Rosemary is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by Bare Root, Container, Cuttings and Seed. It has a slow 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 -3°F. Rosemary has high tolerance to drought and restricted water conditions.
