Botanical description:

Borago officinalis grows to a height of 60–100 cm, and is bristly or hairy all over the stems and leaves; the leaves are alternate, simple, and 5–15 cm 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.

This annual will remain in the garden from year to year by self-seeding.

Seasonal development:

It has an indeterminate growth habit which may lead to prolific spreading. In a 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.

Borage flowers are particularly attractive to bees – after a bee has visited a flower it refills with nectar within two minutes, making borage a great pollinator-friendly plant for a small garden.

It is unclear to what extent mammalian herbivores in North America feed on the foliage of Borage, which is mildly toxic from the presence of pyrrolizidine alkaloids. Similarly, there is a lack of information about the consumption of seeds by birds and rodents.
