(Talinum triangulare) Also known as waterleaf, this tasty and versatile green is one of the most drought- and heat-tolerant edible plants we know. The seeds of this variety were shared with us by Solomon Amuzu of Ghana. He detailed how this plant was one of very few to survive the extreme droughts that Ghana has experienced since the 1980s. The whole plant is edible, from tender stem to leaves and flowers. This reliable and hardy edible food plant is used in salads, soup, stew and baking.
