Facts

Snow wakerobin is native to parts of the Midwest, where it is typically scattered and uncommon. It is not currently a resident of New England. One population known historically from Connecticut, likely originating from planting, may no longer be present. It is one of the smallest and earliest-flowering of the wakerobins (Trillium).
