Erythronium dens-canis produces a solitary white, pink or lilac flower at the beginning of spring. The petals (growing to approx. 3 cm) are reflexed at the top and yellow tinted at the base. The brown spotted leaves are ovate to lanceolate and grow in pairs. The white bulb is oblong and resembles a dog's tooth, hence the common name "dog's tooth violet" and the Latin specific epithet dens-canis, which translates as "dog's tooth".<ref name=RHSLG>Template:Cite book</ref><ref>Linnaeus, Carl von. 1753.
