Carex is a very large genus of over 2,000 grass-like perennials, known as true sedges, found across most of the world. Most grow in damp or wet places, though many garden species tolerate ordinary soil, so match the species to your site.

About
Carex is a vast genus of over 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges; however, those of genus Carex may be called true sedges. Carex is the most species-rich genus in the family. The study of Carex is known as caricology.
Where it grows
Carex species are found across most of the world, albeit with few species in tropical lowlands, and relatively few in sub-Saharan Africa. Most (but not all) sedges are found in wetlands – such as marshes, calcareous fens, bogs and other peatlands, pond and stream banks, riparian zones, and even ditches. They are one of the dominant plant groups in arctic and alpine tundra, and in wetland habitats with a water depth of up to 50 cm (20 in).
