Native Plant of the Week: Snow Trillium ~ Trillium nivale
Other Common Name: Dwarf White Trillium, Lesser Snowy Trillium, Dwarf White Wakerobin
This tiny native Trillium is the smallest Trillium in the Midwest only growing about 4 inches tall. It is also one of the earliest flowering Trilliums, in central Minnesota its flowers can open as early as mid-April. This photo was taken on the 21st of April a couple of years ago.
Wildflowers of Wisconsin book also notes limy soils are preferred.
The status of Trillium nivale is somewhat equivocal. Although it grows in fifteen states and is considered "secure" nationwide, populations are considered "scattered to rare across its range" (NatureServe 2009). The species is listed as endangered or threatened in half of the states in which it occurs, and it is watch-listed or special concern in the remainder of states. (Minnesota DNR)
See the USDA Plants Map for distribution and status for your State.
