The Sedge and Carex grasses are common throughout Canada from British Columbia to Newfoundland. The season is generally from June to July except in Vancouver and Victoria where the season would be from May to June. Although they are wind-pollinated, exposure to pollen of sedge and carex is very limited. They are, therefore, considered to be insignificant allergen contributors. They may possibly be responsible for symptoms of pollinosis but only very locally. They don't produce abundant pollen.
