The term ‘green beans’ refers to the edible fruit of various cultivars of the common bean plant. They are sometimes called string beans, snap beans, or wax beans. There are many different types of green beans: over 130 varieties are known. Depending on the variety, green beans grow as either bush beans (where the plant remains short and bushy, producing beans among its thick leaves) or pole beans, which tend to grow tall, twisting their vines around any nearby supports. Green beans are enjoyed for their mild, sweet flavor, and crisp texture. Generally available year round, green beans come into season during the summer. However, they are often enjoyed at holidays (for example, green bean casserole is an American favorite at Christmas or Thanksgiving).
