Bulgarian
Bulgarian displays much stronger purple-pink colouring than Scarlet runner. On most seeds the black “spiral” by the hilum is much smaller as well. Our original seeds are from Jim Tjepkema in Minnesota who received this variety from a Bulgarian ag scientist. He notes that it is “smaller than German runner bean that I grow, most of the pods are produced in late summer and most of them mature to produce seed before the first frost.”
