Botany with an edge: all about sedges

"Sedges have edges" is a helpful mantra in plant ID to spot this tricky group. Try learning Virginia's sedge diversity with this expedition!

"Sedges have edges; rushes are round; grasses are hollow right up from the ground" is a familiar saying to separate the three graminoid families. LEarning the diversity of form within one of these groups is much more daunting. This expedition will focus on all the genera of sedges found in Virginia. Help the VT Massey Herbarium transcribe their specimen data while practicing ID skills for this tricky but common group of plants!
