Typha latifolia
The marsh areas around Mer Bleue are characterized by plants such as cattails ("Typha latifolia"), alders ("Alnus rugosa"), willows ("Salix" spp.), and a variety of sedges ("Carex" spp.). There are several aspen islands in the centre of Mer Bleue consisting of an overstory of aspen and an understory dominated by bracken fern ("Pteridium" spp.). The edges of the islands are surrounded by small bands of cattail and some alder growth.
