Bean growing in the field from Worcester County Conservation District programming. Glamour shots by Michael Piazza for Edible Boston article on the Worcester Horticultural Bean.
From the Seed Savers Exchange Listing:
Pole, dry. 100 days. Fawn-colored, cranberry-spotted. Most pods contained five or six beans although some nurtured only a couple massive beans. They started out a uniform light green pods, and as they matured, developed pale magenta streaks. Grows 8 feet tall will need trellis or arch. During its heyday, the Worcester-based Ross Bros. seed catalog touted it as, “The Largest Bean, The Longest Keeper, The Brightest Pod, The Most Productive,” even in drought years when seed growers had had mixed results.
