60 days. This bean is absolutely gorgeous! Violet-purple outside and bright green inside, it is fun for kids to grow and has great flavor. The 6 inch long pods turn green after cooking, providing a built-in blanching indicator. Upright, 24 inch tall plants hold their slightly-curved pods off the ground. Like its predecessor, Royalty Purple Pod, Royal Burgundy performs exceptionally well under cool conditions. Rich, delicious bean flavor. Buckskin color seeds; 105 per ounce.
