Native to temperate regions, most sedges or sedges grow near humid places, hence their need for good atmospheric humidity. They produce spike-shaped flowers, but in ornamental horticulture they are of no interest. It is rather their decorative foliage that attracts gardening enthusiasts. The leaves are very sharp, which is also suggested by the name of the genus, which probably comes from keiro, a Greek word meaning to cut. Sedges usually form a very tight clump. These plants are well adapted to Quebec, developing better in cool temperatures. Many sedges tolerate shady situations. They are generally easy to grow plants, requiring little care.
