Borage is one of our companion plants. It is very useful in helping tomatoes grow (increases cropping and also makes them even tastier) and also repels tomato pests like the tomato hornworm. It is also good for protecting legumes, spinach and brassica as well as strawberries. It is also a vege in its own right and can be used in salads or as a garnish.
It also has many health benefits like boosting metabolism and some believe also for hormone management in women. It is also used for colds, flu and chest infections. Looks nice as well.
