Blue Borage Seeds – Edible Flowers & Culinary Herb

Borage (Borago officinalis) is one of the most cheerful and useful herbs in the garden — an easy-growing, free-spirited annual that produces a profusion of striking true-blue, star-shaped edible flowers throughout summer. Blue is one of nature’s rarest edible colors, and Borage delivers it abundantly. The flowers taste sweet like honey with a mild cucumber finish, making them one of the most beloved garnishes for salads, cocktails, and summer drinks. Leaves and young shoots carry the same refreshing cucumber-like flavor and are excellent in teas, infused waters, and culinary blends.

A prolific self-sower, Borage drops its own seeds and returns reliably year after year with no effort — plant it once and enjoy it for seasons to come. An outstanding companion plant that attracts bees and beneficial insects while naturally deterring pest insects from nearby vegetables. Approx. 1,500 seeds per oz.
