Kwintus, Northeaster, and Early Riser have all been distributed as the same bean (Kwintus=Early Riser, Northeaster=Early Riser) . Whether they are all different, two are the same, or all three are the same is lost on me. I'll keep trialing white seeded, very early, stringless, large, flat, green podded varieties under those names to see if I can find any possible difference in them.
