Borage is well known for its edible flowers. The starry sky-blue flowers can, famously, be frozen into ice cubes and, yes, added to drinks. Like lemon, lime and bitters. Mmm. Borago officionalis is an annual herb and (sadly for me) flings seeds around generously. But if you grow it, then salads will look pretty with a sprinkling of these pretty blooms, or use a couple of sprigs to decorate cheese platters.
