It is especially common in East Anglia where it was cut for thatching material because it was more flexible and durable than reed.

Roeddech chi yn gwybod?

Originally, Great fen-sedge was simply known as 'Sedge' - a name which came from the fens of East Anglia. However, botanists decided to use the word to describe a whole family of related plants (Cyperaceae) which are now commonly called sedges.
