It’s been many weeks since I’ve done one of these, but as I’ve just sown some in my garden it felt like a good choice to kick start the series with.
Borago officinalis is an annual plant and prolific self-seeder which can grow to 1m tall and just generally seems to take up a lot of space within very little time – perfect for filling up an empty space with colour. It’s a fantastic companion plant, both attracting beneficial insects and repelling the tomato hornworm. The leaves are rich in potassium, which is needed for fruiting, so it’s a good idea to use the leaves as a mulch around potassium-hungry crops such as tomatoes, peppers, courgettes and squashes. The leaves are also edible, but they are hairy and tough so best picked when young if being used in a salad (shred them finely in either case). They have a cucumber-like taste and were traditionally used in the preparation of Pimms before cucumber and mint became the norm.
The seed of the “Starflower”, as it is also called, is the highest known plant-based source of gamma-linolenic acid, an omega-6 fatty acid thought to be beneficial for the treatment of arthritis, eczema and premenstrual tension. Hemp seed, Evening Primrose and Spirulina are among the other more well-known and widely-sold sources of the same substance.
Borage flowers are a curiosity in themselves as they start off pink, turn to blue in the mid-summer, and often revert back to pink as the summer draws to a close – the latter is thought to be the effects of UV on the flower. They work beautifully as a garnish in salads or cold soups, on cakes or frozen into ice cubes and added to summer drinks. Thanks to Eggs on the Roof for Gazpacho recipe and illustration.
