Up to 50 days. Formerly Burpee Stringless. Crisp pods are 5 to 6 inches long, slightly curved and entirely stringless. Dependable producer, even under adverse conditions! Each plant yields lots of flavorful, dark green, 6-inch, meaty pods that are completely stringless. The burpee variety of green bean is completely stringless and produces a week earlier than many other types of green beans. It can be grown in zones three through twelve, and is tolerant of heat and dry climates. It is also resistant to mosaic powdery mildew, and grows in a bush style, so no supports are needed.
