Borage is an easy growing annual herb plant with vivid blue flowers and leaves and flowers that have the flavor and scent of cucumbers. It is considered an herb but is often grown as a flower in vegetable gardens where it attracts pollinating bees and is considered a good companion plant for tomatoes, squash, and strawberries. It’s even supposed to deter tomato hornworms and improve the flavor of tomatoes growing nearby.Borage is a somewhat gangly plant, but you barely notice it because the star-shaped flowers are so vibrant. They start pink and turn a true blue, hanging in downward facing clusters. Even the fuzzy white buds are attractive. Both the flowers and the leaves are edible, with a cucumber-like flavor. Use the leaves while they are young because as the plant matures, the stalks and leaves become covered with a prickly fuzz.
