Tiny herb-robert blooms from May to November. It is joined in early summer by appendaged waterleaf and false solomon's-seal, and then, in the deep shade of summer, by tall bellflower and lopseed. In the fall, a fringe of woodland sunflower, goldenrod, and a bevy of asters provide one final splash of colour before the onset of winter. In the more northerly areas of the Park, Point Pelee's southern flavour is tempered with an influx of species more typical of central Ontario's mixed-wood forest. Included is a sprinkling of sugar maple, basswood, a variety of species of oak, and a few stands of mature white pine.
Swamps are similar to marshes in that they are wetlands, but here the dominant plants are trees.
Point Pelee has both a marsh and a swamp. The swamp is situated directly south of the marsh in an area which was once a series of beach ridges. It developed when water collected in the troughs between the ridges. The amount of water is controlled by the lake. When levels are high, more water percolates through the sand, flooding the troughs.
