Erythronium grandiflorum subsp. grandiflorum

Glacier lily, Glacier Lily

Family: Liliaceae · Type: perennial · Native

Glacier lily is a California native perennial found in the Klamath Ranges and northern Coast Ranges in subalpine meadows at elevations of 500 to 2,300 meters. Flowering from April to July, this plant produces bright yellow flowers with a pale zone at the base, blooming singly or in small clusters of up to three individual blossoms. Growing with slender stems 20 to 30 centimeters tall emerging from a small bulb, it develops graceful, wavy-edged lanceolate leaves in a rich green color. Its leaves measure 5 to 20 centimeters long, spreading in an elegant pattern around the delicate flowering stem. The flower's inner perianth parts feature distinctive sac-like folds at the base, with white filaments and cream to yellow anthers creating a subtle textural complexity.
