Siberian perennial with remarkable metabolic and tonic effects. Has been studied by Russian scientists used in the Russian athletic training program for decades. A potent ’adaptogen’ that helps athletes increases endurance, reflexes an concentration, and helps them to recover faster from exertion. Studies show that the root extract greatly increases the work capacity of muscles and normalizes blood sugar levels quickly after exertion, and improves memory and learning. Contains ecdysteroids which have anabolic-like growth promoting effects without the side effects associated with drugs. Violet flowers appear in the second year, reaching 80-160cm/30-60in in height. Grows in deep, well-drained fertile soil in full sun. Very hardy. Seeds are said to respond to outdoor exposure in seed flats over winter, but we find that seeds germinate in flats without cold.
