Species Erythronium currently includes 33 accepted species of hardy spring-flowering perennial plants with long, tooth-like bulbs. The leaves are broad lanceolate, plain green in some species, but marbled with brownish-purple in many species, or pale whitish-green in some. The slender flowering stems carry one to ten pendent flowers with six recurved tepals in shades of cream, yellow, pink or mauve. The fruit is a small capsule containing a few seeds. Species are native to forests and meadows in temperate regions of the Northern Hemisphere.

Formerly included Two species names were coined using the name Erythronium which have since been reclassified to other taxa. Erythronium carolinianum, now called Uvularia perfoliata Erythronium hyacinthoides, now called Drimia indica

Cultivation and uses Erythroniums are woodland plants and require rich soil, full of organic matter. Soil should be evenly moist and slightly acidic. They prefer shade or filtered sunlight.

Erythroniums are widely grown as ornamental plants, with numerous hybrids and cultivars having been selected for garden use. Popular cultivars include Erythronium 'Pagoda', E. 'Sundisc', E. 'Joanna', E. 'Kondo', E. 'Citronella', E. californicum 'White Beauty', and E. 'Rosalind'. Propagation is best by seed in autumn or by division of bulbs, depending on species. Some species propagate vegetatively. The plant is also used as a ground cover; it will spread over several years.

The following cultivars, of mixed ancestry, have won the Royal Horticultural Society's Award of Garden Merit: 'Apple Blossom' (white with yellow centre) 'Janice' (pink) 'Joanna' (cream/pale yellow throat) 'Pagoda' (cream yellow) 'Sundisc' (yellow) 'Wildside Seedling' (white/yellow) The bulb is edible as a root vegetable, cooked or dried, and can be ground into flour. The leaves can also be cooked as a leaf vegetable. In Japan, Erythronium japonicum is called katakuri, and the bulb is processed to produce starch, which is used for food and other purposes.
