80-90 Days to maturity. Canavalia gladiata. Shironata Mame Bean Seeds. Non-GMO, annual, open-pollinated, heirloom, pole, snap, Asian, specialty bean. Suitable for growing in containers, garden plots, raised beds, and greenhouses. The “Shiro” (white) in Shironata Mame refers to the white seeds, distinguishing it from red-seeded sword bean types. This unique coloration is culturally significant, and in Japan, both red and white sword beans have been used historically for various medicinal and culinary purposes, including bean-based teas believed to promote health and wellness. Their texture is similar to snow peas. Large vines grow quickly and should be trellised. They also have beautiful blooms that pollinators love. ~20 seeds/oz.
