Trillium flexipes, known as the nodding wakerobin, bent trillium, or drooping trillium, is a species of flowering plant in the family Melanthiaceae.[3][4][5] It is found from Minnesota to Ohio, south to Tennessee , with isolated (and sometimes rare) populations in New York, Pennsylvania, Alabama, and other states.[6] It is an endangered species in Ontario[7] and possibly extirpated in North Carolina.[8]

Description

T. flexipes is a perennial herbaceous plant that spreads by means of underground rhizomes. In northern areas, the flower tends to hang below the leaves, while central and southern strains have a large erect flower.[9] The flower petals are normally white but can be reddish or maroon. The fruit is rosy red to purplish and fragrant of ripe fruit.[4]

T. flexipes is known to hybridize with other Trillium species. In particular, hybrids between T. flexipes and T. erectum can occur. Indeed, the red-petaled forms of T. flexipes tend to occur in regions where the ranges of both species coincide.[10] Hybridization is also suspected between T. flexipes and T. sulcatum.[11]
