Relating to or belonging to the sedge family (Cyperaceae), or resembling sedges in appearance or growth.
From Cyperaceae plus the Latin adjective-forming suffix '-ous.' The root traces to Greek 'kupeiros' and ancient botanical terminology for water plants.
Most people can't tell sedges from grasses, but sedges actually thrive in soils too wet or acidic for grass—they're the plant world's specialists in marginal environments that other plants give up on!
