LATIN NAME: Withania somnifera

COMMON NAME: Ashwagandha

Plant Profile

Withania somnifera, commonly known as Ashwagandha, is a tough, aromatic shrub. Ashwagandha is a small, tough, aromatic shrub of dry plains and sandy ground of warm regions, and it has been a familiar of traditional practice of east for a very long time. Root is part that has been prized through ages, and the whole plant has a quiet, useful presence in the dry garden. It is a tough, easy plant of open, sunny ground. Add these qualities together and you have a species well worth a place in the garden.

Science & Biotechnology

Ashwagandha’s signature constituents are the withanolides, steroidal lactones concentrated in the root. Standardised root extracts (typically 300–600 mg daily) have been tested in a series of randomised trials in stressed adults, reporting reductions in serum cortisol of roughly a quarter to a third alongside improved stress, anxiety and sleep scores; a 2021 systematic review of seven trials and 491 participants reached similar conclusions. A 12-month prospective safety study of 600 mg daily in 191 adults found no deleterious effect on hepatic, renal or thyroid function, though isolated case reports of liver injury exist worldwide. It is traditionally contraindicated in pregnancy and may potentiate thyroid medication.

Within the Withania group, Withania somnifera is of continuing interest to researchers working on plant diversity, seed biology and the selection of improved garden forms. Ashwagandha has a strong and growing presence in plant science, and root has been subject of a long line of phytochemical and pharmacological research. It is the kind of species that plant scientists reach for when they need reliable material for propagation and selection studies.

Uses & Benefits

Beyond its ornamental appeal, Ashwagandha has the practical versatility that makes a plant worth growing from seed year after year. Ashwagandha is one of the most widely used of the traditional herbs of the east, and the dried root has been traded and valued for a very long time. Plant is now grown as a serious medicinal crop across warm regions, and root is used in traditional preparations and modern supplements alike. Around garden plant is a tough, easy, silver-leaved shrub of dry, sunny ground, and it brings a quiet, useful presence to the border. Once it has its roots down, it more or less looks after itself.

Ashwagandha, Withania somnifera, is Ayurveda’s supreme rasayana and the world’s best-selling adaptogen: human trials support its withanolide root extracts for stress, sleep, strength and cortisol balance. It is one of the few tonic herbs with genuinely modern clinical evidence.

Growing from Seed

Ashwagandha is one of those generous plants that come along well from seed. Level a tray of loose seed compost, sow evenly, cover to about the seed’s own depth, and keep it moist in full light. Shift the seedlings into small pots as soon as they can be handled, and give them bright light until planting-out time.

Our Take

Its role in herbal practice, noted above, adds depth to an already garden-worthy plant. Being a tough, aromatic shrub, it asks for a permanent spot and repays it yearly. Sun, free drainage and a patient first year are all it really requires.
