A newcomer this year to our herb garden is unexpectedly boisterous and intriguing: The herb borage joined one of our two herb beds at the end of April, when we redug and redesigned them. It's already a hearty bush, about three feet tall and right now in heavy bloom. Known also as "starflower", its blooms appear on the plant in both blue and pink versions--apparently younger and older flowers. The honey bees are enjoying the plant immensely; the plant is known for producing good honey, and we're always happy to see pollinators in the garden. We're just learning about borage, since it isn't commonly found in North American herb gardens. It's a probable native of North Africa that has spread across Europe, Asia Minor, the Mediterranean, and South America. Borage is apparently easy to grow from seed, but we acquired our plant from Mahoney's; it's an annual that is said to reseed itself easily, so we won't need to shop for it next year.
We might have made more of the plant's role in companion planting, had we known: it repels tomato hornworms if planted with tomatoes--and cabbage worms when planted with brassicas (hurray!). The plant debris is also a helpful mulch; it contains high levels of calcium and potassium which help the setting of fruit for all fruits and vegetables.
The whole plant is edible, the leaves having a cucumber flavor (I can vouch for that, though the fuzziness of the leaves is a little odd on the tongue), the blooms somewhat honey-sweet; the flower is often used to decorate desserts as it is one of very few truly blue-colored edible substances. It can be used both as a fresh vegetable (in salads and soups) and as a dried herb (in tea).
