Erythronium revolutum is a deciduous herbaceous, perennial with a clump forming habit. Its dark green, mottled  leaves appear in pairs, are lanceolate to ovate with entire margins, up to 25cm long and 12cm broad. Its pink flowers are Lilly like, up to 6cm across and appear singularly on long, naked stalks. Its roots emerge from an oval shaped bulb which is up to 5cm long.

Erythronium revolutum, commonly known as Mahogany Fawn Lily, Trout Lilly, Coast Fawn Lily, and Pink Fawn Lily, is native to the west coast of North America. In its native habitat it is found on stream banks, bogs and wet forests.

The etymological root of the binomial name Erythronium is derived from the Greek erythros meaning ‘red’, as to what the red refers to in this species we are unclear. Revolutum is derived from the Latin revolutio meaning ‘turn’, in reference to the nature of the flowers.

The landscape architect may find Erythronium revolutum useful in shady damp locations including woodlands and stream and lake banks.

    As Erythronium was originally published by Linnaeus as including only E. dens-canis, which is not red-flowered, the name cannot refer to the flower color.
    The name previously had referred to some Greek plant whose root or bulb had a red outer coat.
