A close relative of ordinary chives, and used in just the same way to flavour cooking, garlic chives have flattened, strappy leaves and a pleasantly garlic taste particularly when leaves are snipped off young. The big healthy clumps come back year after year, and in late summer the starry white flower heads are a real bonus, much loved by bees. The flowers can be eaten too: pick just after they open and sprinkle on salads for a pretty and spicy garnish.
