Michigan Lily (Turk’s Cap Lily)
Perennial lily with an unbranched, hairless stem, growing from a stout bulb. Flowers single or in whorls of 2-5, on stems arising from upper leaf axils, nodding, with 6 tepals (3 sepals and 3 petals, all 6 alike), orange with many purple spots, recurving; the 6 stamens and the stigma protrude prominently. Blooms June-July. Leaves lance-shaped, mostly whorled, sometimes alternate at the lowest and highest nodes, to 5 inches long and ¾ inch wide, roughened with minute, toothlike processes along the margins and veins.
Similar species: Tiger lily (L. lancifolium) has only alternate leaves and forms bulblets at leaf axils; a nonnative, it does not persist long out of cultivation. Wood lily (L. philadelphicum) has flowers erect, not nodding; possibly extirpated, it may still occur in some northern native prairies. Swamp lily (L. supurbum) has smooth leaves, lacking teeth; it has been found only in Perry County.
