Erythronium albidum, the white fawnlily or white trout lily, is a small herbaceous geophyte in the lily family. It is also known as adder's tongue, white dog's-tooth violet, serpent's tongue, trout lily, deer tongue, and yellow snowdrop. Large numbers of this plant indicate that the woodland has never been subjected to heavy machinery, where it would be unable to grow due to soil compaction.
Morphology
The white fawnlilies often forms extensive colonies in which immature, non-flowering, 1-leaved plants far outnumber flowering, 2-leaved ones. Flowering 2-leaved plants produce a short, slender, red stem 10–15 cm (4–6 in) tall, which bear two oblong basal leaves. The leaves are lanceolate, 8–16 cm (3+1⁄4–6+1⁄4 in) long and 3–4 cm (1+1⁄4–1+1⁄2 in) broad, dark green and covered with a mottled pattern of purple blotches. It is difficult to distinguish between Erythronium albidum and Erythronium americanum based solely on leaves. The root system consists of a central corm that sends out stolons which allows plants to slowly spread to form large colonies. The corms of this lily supposedly resemble dog teeth. Foliage of this plant withers away during the summer.
At the end of the stem, the plant produces a white, lily-like flower 3–4 cm (1+1⁄4–1+1⁄2 in) in diameter, with six white tepals (3 petals and 3 petal-like sepals) and six yellow stamens. The backs of the tepals are often violet in color near to where the attach to the stem. The flowers are bent downward, and elongate with age. At night the flowers close and don't reopen until morning. Flowers bloom in mid to late spring. The fruiting body is a ovular three chambered capsule and can reach up to 2.5 cm (1 in) in length.
Distribution and Habitat
Native to eastern North America, the white fawnlily can be found from southern Quebec and southern Manitoba, and south to Georgia and Texas. The plant is mostly found in large groups on the forest floor, often in areas following ground disturbance. Its preferred growing conditions are in part sun to mostly shade and deep, moist loamy soils.
