Trillium nivale, the snow trillium[2] or dwarf white trillium, is a member of the Melanthiaceae family. It is native to parts of the east and midwest United States, primarily the Great Lakes States, the Ohio Valley, and the Upper Mississippi Valley.[3][4] It is one of the earliest flowers to bloom. Along the Ohio River valley, flowers may be seen in early March. At its northern limit in Minnesota, it blooms in early April.[5]

Trillium nivale is smaller than many of the other species in the genus, seldom reaching a height of more than 9 cm (3.5 in). Unlike most trilliums, it does not grow in leaf mold, preferring limy sandy gravel, crevices in limestone, or calcareous mineral soil instead.[5][6]
