Taxonomy:
It is worthy to note that there continues to be debate over the trillium species. Trillium has its ‘lumpers’ and its ‘splitters’. On some days I’m a lumper and other days I’m a splitter. When I encounter a trillium that has unique features that don’t fit, I find it best to be a ‘trillium lover’ and just enjoy it. I provide the list below to show man’s perfections and imperfections at organizing and understanding God's great trillium work.
