Carex species are perennials. They are easily confused by beginners with ornamental grasses because their foliage is very grass-like. But stems of the true grasses are typically hollow, and their shape is either flat or rounded. Sedge stems, by contrast, are solid, and they are triangular in shape. If you wish to put this identification aid to a touch test, be sure to feel the stem (the part of the plant closest to the ground), not the leaf. Sedge plants are generally great plants for areas with wet soil. Here are 10 of the most popular true sedge species.
