Kew Pollination Collection Borage Seeds


A beautiful hardy annual herb with rough leaves covered in silvery hairs and the most attractive celestial-blue flowers.

This versatile upright herb has a multitude of uses - add the cucumber-flavoured leaves to summer drinks and salads, grow it as a companion plant close to other crops to attract pollinating insects, and at the end of the season plants make a useful bulky addition to your compost heap.

  • Sow from March to May in full sun
  • Height: 60cm. Spread: 45cm
  • 1 packet contains approximately 100 seeds
  • Attracts bees and other pollinators

Direct sow borage seeds outdoors where they are to grow from March to May. Borage seed germinates best at a temperature of around 15-25C. Borage will grow in most soils but prefers a position in full sun on well-drained soil which has been raked to a fine tilth. When growing borage, sow seeds thinly, at a depth of 6mm in drills spaced 30cm apart and cover the seed with its own depth of soil to exclude light. Water the ground regularly, especially during dry periods. When seedlings are large enough to handle, thin them to 23cm apart.

Borage plants will self-seed freely if left unchecked but are neither invasive nor unwelcome in most cases. If seedlings are not wanted, deadhead as the blooms fade or weed them out whenever they appear.

A great many of our favourite garden plants can be harmful if eaten or handled without gloves. This is rarely a cause for concern but it's always good to know what you are dealing with.

In the case of borage, allergic reactions are uncommon. Borage is a fine source of calcium and potassium and is recommended for toning up the glandular system, and all bronchial, lung and chest disorders. However, you should always check with your doctor before using herbs for medicinal purposes. Borage flowers are edible and are wonderful used to garnish summer drinks and salads.
