Brown Dutch Caseknife Pole Bean 
Phaseolus vulgaris 
Used as a snap bean, a shelling bean, or as a dry baking bean, this is one of the oldest (pre-1800) pole beans grown in colonial America. It takes its name from the broad, curving, flat pods which resemble old-style case knives.  This variety has brown seeds instead of the more common white seeded forms.  RARE!  Minimum 25 seeds, $4.50. Germination 98%.
