Chives
Hardy perennial. 1–2′ hollow grasslike leaves enhance any dish with their subtle onion flavor. Lilac-colored flowers bloom in June and July, can be eaten or enjoyed in arrangements fresh or dried. Chives are used in Asia as a remedy for colds and flu. For best production, grow in well-drained soil and divide clumps every few years. Nearly indestructible even with neglect in extreme conditions. I have found they do like shade during at least part of the day if you have it. They are not too fond of our summers.
