I sowed some Borage (above) seed today undercover in the greenhouse. It's a good companion plant as the flowers attract bees which aid in pollination. This is particularly said to be the case with strawberries and runner beans. Like marigolds, borage also attracts blackfly, thus hopefully drawing it away from other plants. You can also buy White Borage (I got mine from CN Seeds) which is a bit more unusual. Both flowers and leaves can be eaten and are a good addition to salads or drinks like Pimms. I like using it medicinally for summer colds or flu. It is a diaphoretic so lowers fever when taken hot. For borage tea, add a small handful of fresh leaves to aprox 500ml of boiling water and simmer for 5 minutes. You could also add honey and lemon.
