Borage Growing Guide - Seeds In A Cup®

History of Borage

Borage (Borago officinalis) hails from the Mediterranean, used since Roman times for its cucumber-like flavor in salads and as a medicinal herb to lift spirits. In medieval Europe, it was known as a courage-booster, often added to soldiers’ wine. Today, its edible flowers and leaves are popular in culinary and herbal uses.
