Erythronium americanum (Trout lily, Yellow trout lily, Yellow dogtooth violet) is a herbaceous flowering plant in the family Liliaceae.

The range is from Labrador south to Georgia, west to Mississippi, and north to Minnesota.[1] Trout lilies grow in colonies that can be up to 300 years old.[2][3]


The common name "Trout lily" refers to the appearance of its gray-green leaves mottled with brown or gray, which allegedly resemble the coloring of brook trout.[2]

It blooms in early spring with nodding one-inch yellow flowers, the petals (3) and petal-like sepals (3) recurved upward. Each plant sends up a single flower stem with a pair of leaves.[1][4]
