90 Days to maturity. Glycine max. Kouri Soybean Bean Seeds. Non-GMO, annual, open-pollinated, heirloom, high-yielding, bush, shell, soybean, Asian bean. Suitable for growing in containers, garden plots, raised beds, and greenhouses. Brown-seeded soybeans are uncommon in the United States. They are highly prized in Japan for their sweeter and nuttier flavor than traditional green, black, or tan-seeded soybeans. Even though the seed for planting is brown, you will find the color of the bean dark green at harvest, and it retains this color when cooked. The bushy plants are early-maturing and need warm days and cool night temperatures for good results. ~175 seeds/oz.
