Notes: White Trillium is the provincial flower of Ontario. Unfortunately, in the latest vesion of the offical logo, the White Trillium looks like it has been run over by a truck!   Contrary to popular belief it is not illegal to pick White Trilliums in Ontario. However, if the leaves as well as the flower are picked, the plant could die as it no longer has any means to produce the energy it needs to take it through the winter into another spring.
