"Trillium luteum s a species of flowering plant in the family Melanthiaceae, with native populations in the Great Smoky Mountains of the USA and surrounding areas. It occurs in parts of North Carolina, Georgia, Tennessee and Kentucky, usually in the shade of mature deciduous trees. It is especially abundant around Gatlinburg.

Growing to 16 inches tall by 12 inches wide, it is an herbaceous perennial flowering in spring. It is cultivated in temperate regions for its variegated leaves and yellow, lemon-scented flowers. It has gained the Royal Horticultural Society's Award of Garden Merit.

Escapes from cultivation have been noted as far north as the northern Berkshires in Massachusetts and Saginaw, Michigan."
