Yellow nutsedge, known to Texans as yellow nutgrass, is a tough weed to get rid of. Roots may go out over two feet, and as deep as 15 inches. Its secret-survival-weapon, however, is the nut-like tubers at the bottom of the picture. Dig it all you want, miss one of those nut-like tubers, and it will be back next season. The same tubers are edible, tasty, and nutritious food – and were consumed by humans and hominids (prehumans) for 2 million years.
