Grass, rush or sedge?
My colleague Paul, ecologist, let me into the ‘secret’ of how to tell them apart:
“Rushes are round, sedges have edges and grasses have holes like a**es.”
To make that slightly more technical, we are talking about the cross section of the stem that carries the flowers. Cut across the stem and you’ll find a rush is round and filled, a grass is round and hollow and a sedge has a triangular or other cross section with ‘edges’. Largely, that is.
