Carex is a large genus of over 2, 000 species[1] of herbaceous plants in the Cyperaceae family. Other members of the Cyperaceae family are also known as sedges, but those in the Carex genus may be referred to as true sedges, and it’s the most biodiverse genus in the Cyperaceae family.
All Carex species are perennial, though some species such as C. viridula and C. bebbii can bear fruit in the first year of growth. Carex leaves consist of a lamina that moves away from the stem and a sheath surrounding part of the stem.
