This native, perennial member of the lily family resembles the Canada lily (L. canadense) but the spotted flowers are more orange than yellow. The six flower tepals (3 petals and 3 sepals) are completely reflexed (bent backwards) to form the structure that is said to resemble an early Turk’s cap. The flowers tend to droop downwards from a tall stem. The center of the flower has a green star. The spots are reddish-brown. It is the largest and most spectacular of the native lilies with flowers up 2.5 inches in diameter and 1 to 12 flowers on average growing on a single plant. In garden settings, the plant can have up to 40 flowers. The six stamens with brown anthers are also longer than those of the Canada lily, projecting far beyond the petals. There is a single pistil that also projects outward. The flower provides nectar for hummingbirds and larger insects. The fruit is a capsule with many seeds.

The leaves are in whorls around the stem, especially on the lower part of the stem. Near the top the leaves may be clustered or in pairs. The plant grows 3-7 feet tall in wet meadows, swamps and low woods.

It is found throughout much of eastern North America south to the Florida panhandle. The blooming period is July to late August. Some Native Americans are said to have used the bulbs to make soup. In some areas it is known by the common names turban lily, swamp lily or American tiger lily. There is some resemblance to the introduced day lily (Hemerocallis fulva), but this alien species has unspotted flowers and sword-like leaves.

Grows in low woods, moist meadows, wetland margins, seepage forests and river banks. Prefers full sun to part shade in consistently moist to wet humus-rich soils.

Found in most counties in the state.  See distribution map at BONAP.

Range: Native to the eastern and east‑central United States, from southern New England and New York west to Illinois and Arkansas, and south to the Gulf Coast states

Flowers mid-July into August. Bloom duration is 2-3 weeks.

Inflorescence  loose, branched cluster of avg. 1–12 nodding flowers at the top of the stem, with additional pedicels sometimes arising from upper leaf axils

Flowers  nodding, large, 2.5″ across, 3-4″ long; perianth orange to orange-red, with reddish-brown spots; 6 petal-like tepals strongly recurved; 6 stamens with long orange filaments and brown anthers, extending beyond tepals; single pistil with orange style and 3-lobed stigma

Leaves  mostly in whorls of 3–9, with occasional alternate leaves between whorls and closer to top; lanceolate, entire, upper surface smooth, lower surface nearly so

Stem  single, erect, glabrous; unbranched below, with several short flowering branches near the top forming a loose candelabra

Fruit  dry, dehiscent, 3‑valved capsule; cylindrical to slightly ovoid; about 1″ long; seeds numerous, papery, flattened, broadly winged

Height  avg. 4-6 feet; max 7 feet

Petal-like tepals are strongly recurved and tepal bases form a distinct green star.

S-rank:  S5 (Secure)
G-rank:  G5 (Secure)

Hummingbirds, swallowtail butterflies (including Eastern Tiger Swallowtail), other large butterflies, and visiting bees forage at the conspicuous, recurved flowers for nectar.

Deer browse the foliage, and small mammals may feed on the bulbs, making the species both a nectar resource for mid‑summer pollinators and a structural component of moist‑soil plant communities.
