There are more than 2000 species of grass-like plants in this genus, known as sedges. According to the Hoffman Nursery, they fall into three groups based on where they come from. Those native to Asia, New Zealand and to North America.
Asian sedges are well adapted to shade and are often variegated and most of them are evergreen. The sedges from New Zealand can take more sun and provide some striking colors such as deep red, bronze or orange. The North American sedges are becoming popular as a living mulch. They are considered an alternative to the traditional lawn, especially in shady locations, or in bioswales.
