Cultivation Borage is not a fussy plant, but the richer the soil, the bushier the plant will be. It prefers full sun, and needs protection from wind as it is easily blown over. Seeds can be sown throughout the season, and once growth is established, it will continue to seed itself. Place plants close together so they can support each other. A plant or two in an indoor pot will provide leaves all winter, but it will need lots of sun.
Borage is an excellent companion plant for tomatoes, squash and strawberries.
The plant actually improves the flavor of tomatoes growing nearby. Culinary Uses Borage flowers and leaves are the traditional decoration for gin-based summer cocktails, and may be set in ice cubes to garnish other drinks. The flowers and young leaves may be used to garnish salads. Candied borage flowers make attractive cake decorations. Chopped leaves can be added to soups and stews during the last few minutes of cooking.
