3662 - Neckargold. 60 days. Neckargold is a yellow wax pole bean with high yields of crunchy 8" pods with excellent sweet flavor. The straight pods are 1/2" wide and semi-flattened - a little like an Italian bean. Neckargold would be an excellent choice for a market garden. The vines are vigorous climbers which easily top 8 feet, so you need some serious support.
