It is an annual herb in the flowering plant family Boraginaceae. It is native to the Mediterranean region and has naturalized in many other locales.It grows satisfactorily in gardens in the UK climate, remaining in the garden from year to year by self-seeding. The leaves are edible and the plant is grown in gardens for that purpose in some parts of Europe. The plant is also commercially cultivated for borage seed oil extracted from its seeds.
Borago officinalis grows to a height of 60–100 cm (2.0–3.3 ft), and is bristly or hairy all over the stems and leaves; the leaves are alternate, simple, and 5–15 cm (2.0–5.9 in) long. Flowers are most often blue, although pink flowers are sometimes observed. White flowered types are also cultivated. The blue flower is genetically dominant over the white flower.Traditionally borage was cultivated for culinary and medicinal uses, although today commercial cultivation is mainly as an oilseed. The seed oil is desired as source of gamma-linolenic acid (GLA), for which borage is the highest known plant-based source.
