Although sometimes submerged within Trillium erectum, T. vaseyi has a later blooming season, a nodding flower of much larger size, a sweet fragrance, and cove habitat unlike that of T. erectum. In my garden hybridization experiments, T. vaseyi hybrids have different color patterns than T. erectum hybrids. Trillium vaseyi is clearly a distinct species. It frequently hybridizes with T. rugelii.
