Trillium spp.

Trillium cernuum - Found in Ontario in moist forest habitats in the southern boreal forest and the mixed forest, becoming increasingly rare south of the Canadian shield. Note the downward pointing, nodding flower and the 6-lobed berry. Source: Dickinson et al. (2004) and McKay & Catling (1979)

Trillium erectum - Found in moist rich forested sites in the mixed and deciduous forest regions. Note the very wide leaves. In addition to their dark red color flowers smell foul, as they are pollinated by carrion flies. Source: Dickinson et al. (2004)

Trillium grandiflorum - Found in rich forested sites in the mixed and deciduous forest regions. This is the provincial flower of Ontario. Toward the end of the flowering period the petals turn pink; infection by mycoplasma-like organisms can result in green-striped petals. Source: Dickinson et al. (2004) and McKay & Catling (1979)
