Sedges

Cyperaceae spp.

Also known as: water sedge. 

Also known as: water sedge. 

Sedges thrive in wet places and have triangular (3-sided) stems. There are about 2000 species of grass-like perennial herbs in the sedge grass family. They are found worldwide, but they are most common in temperate and cold regions. Sedges can be distinguished from grasses by their solid, 3-angled flower stems (grasses have round, hollow flower stems). Most species of sedges form a dense, compact clump.
