(Allium schoenoprasum). Mild, onion flavored favorite that could not be easier to grow. Chives can be used in almost any dish; we add them to tuna and chicken salad, eggs and quiche, soups, dips, salad dressings, fish, etc. And what baked potato is properly dressed with out them? Purple flowers are also edible, adding great color to salads. Perennial.
