White Trillium (Trillium grandiflorum)
Trillium grandiflorum is most common in rich, mixed upland forests. It is easily recognised by its attractive three-petaled white flowers, opening from late spring to early summer, that rise above a whorl of three, leaf-like bracts.
It is an example of a spring ephemeral, a plant whose life-cycle is synchronised with that of the deciduous woodland which it favours, flowering before the trees unfurl leaves and cast the forest floor into shadow. White trillium often occurs in dense drifts of many individuals.
