Blue Coco Pole Bean 12 Seeds

Phaseolus vulgaris

Blue Coco Bean is a rare and historic French heirloom pole bean dating back to the 1700s, prized for its beautiful deep purple pods and rich, nutty flavour. This vigorous climbing variety produces abundant harvests of flat, tender pods that are excellent for fresh eating, cooking, or drying.

The striking purple pods turn green when cooked, adding a fun and surprising element to the kitchen. Blue Coco is highly versatile—harvest young for snap beans, use as shelly beans, or allow to mature into meaty, flavourful dry beans. 

Days to Maturity: 60–70 days (snap), 90 days (dry beans)
