Minnesota Dwarf Trout Lily

The Minnesota dwarf trout lily is an endangered plant that blooms during early spring in the woodlands of southeastern Minnesota in the Cannon River valley. As a spring ephemeral, the trout lily blooms, along with many other woodland wildflowers, when sunlight reaches the forest floor before deciduous trees fully leaf out. A good place to see the dwarf trout lily is at Nerstrand-Big Woods State Park.


The Minnesota dwarf trout lily was listed as endangered on March 26, 1986 because its existence was threatened due to loss of woodlands that were converted for agriculture and housing developments or extensively logged.


About half of the known populations of the Minnesota dwarf trout lily are on public lands where they are protected. On private lands, many populations and the surrounding woodlands are voluntarily protected by landowners.
