longbract trillium, Trillium underwoodii

Longbract trillium has a reputation for confusion. Even after the flowers open, the plants continue to get teller, passing through phases that resemble other species. At first they can look a lot like T. reliquum, which it sometimes grows with. When taller they are more like T. cuneatum. The Cases in their Trillium book say that only after you've seen them many times can you become confident that you know which Trillium you're seeing. You will see these in woods in AL, FL, and GA. Edgewood Garden, Chester Co PA, 4/21/21. Trillium family, Trilliaceae.
