Borage is a versatile and easy-to-grow annual herb that offers numerous benefits to gardens. This hardy plant thrives in various conditions and attracts beneficial insects.

Cultivation Conditions

Borage plants prefer full sun exposure but can tolerate partial shade. They grow best in well-drained soil with a pH between 6.0 and 7.0. Prepare the soil by incorporating organic matter to improve drainage and fertility. Sow seeds directly in the garden after the last frost date, spacing them about 12 inches apart. Water regularly until established, then reduce frequency as borage is drought-tolerant once mature.

Borage grows quickly, reaching heights of 2-3 feet. It adapts well to container gardening, making it suitable for small spaces or balconies. For a continuous harvest, succession plant every few weeks throughout the growing season.

Garden Benefits

Borage, also known as starflower or bee flower, offers multiple advantages to gardeners. Its bright blue flowers attract pollinators, particularly bees, enhancing overall garden productivity. The plant serves as a companion for various crops, improving their growth and flavor.

Borage leaves and flowers are edible, adding a cucumber-like taste to salads and garnishes. The plant’s deep taproot helps break up compacted soil and brings nutrients to the surface, benefiting nearby plants.
