Borage

Borage (/ˈbʌrᵻdʒ/,Borago officinalis), also known as a starflower, 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.

Description

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. The flowers are complete, perfect with five narrow, triangular-pointed petals. 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. The flowers arise along scorpioid cymes to form large floral displays with multiple flowers blooming simultaneously, suggesting that borage has a high degree of geitonogamy (intra-plant pollination). It has an indeterminate growth habit which may lead to prolific spreading. In temperate climate such as in the UK, its flowering season is relatively long, from June to September. In milder climates, borage will bloom continuously for most of the year.
