About Borage
Borage is an effortless annual with striking blue star-shaped flowers. The cucumber-flavored leaves and flowers are edible, and it is a powerful pollinator magnet that self-seeds freely year after year.
Direct sow after last frost — hates transplanting. Self-seeds so aggressively you plant it once and it returns every year. Great companion plant for tomatoes and strawberries. Harvest flowers daily to encourage more blooms.
