Description

Erythronium americanum is a low growing plant with two tulip-like, green and purple mottled leaves, the appearance of which led to the common name trout lily. Elegant, 1" long, yellow flowers rise above the groundcover-forming foliage on delicate bare stems. It is more common, and similar to the Erythronium albidum which is larger and has white flowers.

Cultivation

Under ideal conditions, the dogtooth violet will slowly colonize without becoming invasive. It prefers moist, rich deep soils that will allow it to spread by underground stolons. It is native to deciduous forests and blooms in spring before the new canopy becomes dense. Foliage will die back in summer as the plant enters its dormancy stage. Bloom times can vary from February to April. Zones 4-8

Propagation

Plants are best left undisturbed until they become over crowded. Easy to propagate by separating corms from mature plants in late summer or fall when dormant. Can be propagated from seed, but new plants can take up to 5 years to produce flowers.

Additional Notes

The common name dogtooth violet is a reference to the appearance of the corms which resemble dog teeth. However, this is not a violet but rather a lily. Deer may find the leaves of this plant to be an irresistible early spring treat.
