Hardy, perennial, and easy to grow, the chopped stems and pink flowers add a fresh, mild green onion flavour to sandwiches, salads and baked potatoes. Clumps can be divided in spring or fall. If grown in containers, divide frequently enough to provide for constant lateral growth. Chives are surprisingly hardy and can be harvested all winter if given some protection from extreme cold. They are also quite drought tolerant, so they're good candidates for xeriscaping. The edible flowers are highly attractive to bumblebees, hoverflies, and other beneficial garden insects.
