What does erythronium mean?
An erythronium is any member of Erythronium, a genus of about twenty to thirty species of spring-flowering bulbous perennials belonging to the lily family. Native largely to temperate woodlands of North America, Europe, and Asia, these plants produce delicate, nodding, often reflex-petaled flowers in shades of yellow, white, pink, or mauve, held above a pair of broad leaves that in many species carry distinctive brownish mottling. Because of those markings, North American species are commonly called trout lilies, while the name dog's tooth violet refers to the pale, tooth-like shape of the bulb; fawn lily is another regional name. Gardeners prize erythroniums for brightening shady corners in early spring, and they naturalize well under deciduous trees. The scientific name derives from the Greek word for 'red', a nod to the reddish tints some species display. In formal writing the genus name is capitalized and italicized, but 'erythronium' is widely used lowercase in horticultural contexts.
nounAny plant of the genus Erythronium, a group of spring-flowering bulbous perennials in the lily family, bearing nodding flowers on slender stems and typically two broad leaves. Common members are known as trout lilies and dog's tooth violets.
- A spring-flowering bulbous perennial of the genus Erythronium in the lily family, with nodding flowers and often mottled leaves.
"In early April the woodland floor was starred with the yellow blooms of erythronium."
"She planted drifts of erythronium beneath the old beech trees, where their mottled leaves caught the early spring light."
"The garden guide noted that Erythronium dens-canis, the European dog's tooth violet, has been grown in gardens for centuries."
The anglicized plural 'erythroniums' is standard in general and horticultural writing; a Latinized plural 'erythronia' occasionally appears but is rare.
"Naturalized erythroniums will spread slowly into large colonies over several seasons."
The dog's tooth violet isn't a violet at all — it got that name because its pale, pointed bulb looks exactly like a dog's canine tooth.

Etymology of erythronium
The name comes from New Latin Erythronium, adopted by Linnaeus in the 18th century from earlier botanical usage, ultimately deriving from the ancient Greek 'erythros', meaning 'red'. The allusion is generally taken to refer to the reddish coloration found in some species' leaves, flowers, or bulb tunics. The Greek root also gives us medical terms such as erythema and erythrocyte, making these distant cousins of the flower's name.
How erythronium is actually used
A botanical term used mainly in gardening and natural-history writing; in everyday speech gardeners more often use the common names trout lily (North American species) or dog's tooth violet. In formal botanical writing the genus name is capitalized as Erythronium and italicized.
Easily confused with erythronium
Erythema is redness of the skin caused by inflammation, whereas an erythronium is a flowering woodland plant; they share only their Greek root for 'red'.
