Ashwagandha, Vedic

(Withania somnifera) Grows 2 to 3 feet tall. This ecotype is the one most commonly used in herbal medicine. Traditional usage (Ayurveda): energy and sexual tonic. Plant prefers full sun, fast-draining, alkaline (pH 7.5 to 8.0) soil and moderately dry conditions.  Sweeten regular garden soil with ground limestone.  In colder zones, at the end of the first season, when the tops freeze back, dig the root, wash, cut up and dry the pieces for herbal use.  In the warmer zones, it is possible to harvest a larger root in the fall of the second year.
Please do your own research before using/consuming any plant. The berries may have toxic qualities if consumed so do not plant where children might mistake them for ground cherries or other berries.
