The Agate is an excellent tasting edamame heirloom with high yields. Agate was originally introduced to the U.S. from Japan in the 1920's. This variety produces high yields of small olive green seeds with brown saddles.
Envy is an early harvesting edamame for shorter growing seasons. Envy produces erect bush bean plants that reach about two feet in height and produce pods each containing two to three green seeds. Edamame is a popular snack in Japan, served with beer. Due to its health benefits that other snacks do not provide, it is becoming popular in the United States.
