Similar Species: Nodding Trillium is the only species with an entirely white flower on an flowerstalk reflexed below the leaves. If flowers are not present: Painted Trillium (T. undulatum) can be distinguished by its stalked leaves; White Trillium (T. grandiflorum) grows in a similar habitat but usually in fairly dense beds; Red Trillium (T. erectum) usually grow as scattered individuals and have somewhat narrower leaves and the fruit/flowerstalk (if it persists) is erect.

AKA: whip-poor-will flower
