Tankuro Soybean

In Japan, black-seeded edamame varieties are deemed to have a richer and sweeter flavor than the green or tan-seeded kinds. Tankuro was the winner for productivity and pleasing flavor in our 2010 trial to find the best black-seeded variety. In 2010’s exceptional heat, our May 25 planting produced robust 3' plants loaded with pods packed with an average of 2.4 beans each. They ripened beginning Aug. 17, the same day as Shirofumi . Harvesting would be 1–2 weeks later in a season with average heat units. Pick promptly when the immature seeds are bulging yet the pods are still dark green, before the plants begin to yellow. Those pods that you miss will dry down, maturing beautiful black pearls that can provide your next year’s planting stock.
