| Trillium erectum|
Color variant of red trillium in bloom compared to large-flowered trillium, Hocking County, OH, April, 2018
Note the slimmer petals and sepals of the T. erectum, and how the flower of T. grandiflorum is deep and cupped, while T. erectum is flatter and tight to the sepals. Both have flower on stalk above broad leaves, and may grow together.
