Borage, also known as a star flower, is an annual herb. It is native to the Mediterranean region but has naturalized in many other locales. It grows satisfactorily and remains in the garden from year to year by self-seeding.

The leaves are edible and borage seed oil can be extracted from its seeds. Long hairs on the leaves and stems is a feature of the species.

Borage grows to a height of 60–100 cm. The 5–15 cm long leaves are alternate. The flowers have five perfect, narrow, triangular-pointed petals.

Flowers are most often blue in color, although pink flowers also exist. White flowered borage is also cultivated. But the blue flower is genetically dominant over the white flower.

The flowers arise to form large floral displays with multiple flowers blooming simultaneously. It has an indeterminate growth habit leading to prolific spreading. In mild climates, borage blooms continuously for most of the year.

Traditionally borage is used in treating several disorders. Colic, cramps, diarrhea, asthma, bronchitis, cardiac problems and hypertension can be treated with borage. It is a blood purifier and helps in treating urinary, kidney and bladder disorders also.

Borage regulates metabolism and the hormonal system. It is a good remedy for PMS such as the hot flush. The flowers can be prepared in infusion.

Borage can be grown as a companion plant to protect legumes, spinach and strawberries. It is a good companion plant to tomatoes because it confuses the mother moths looking for a place to lay their eggs.
