The most common varieties of green beans include plain green beans (Blue Lake is a good variety), Italian (flat Romano), purple-podded (indistinguishable from baby green beans when cooked), yard-long, and wax beans (which are usually pale yellow).

Many similar varieties are also available, including baby French, haricot, and Chinese long. Baby French and haricot beans are thinner and more tender than conventional long beans. Chinese long beans measure 12 to 14 inches (30.48–35.56cm) in length and are prepared the same as regular green beans.
