The three bracts have generally lance-shaped blades up to {{convert|11|cm|in|frac=3}} long borne on petioles. The blades are glossy blue-green with silvery venations. Atop the whorl of bracts is a single nodding non-fragrant flower with green sepals and pink-blushed white petals up to {{convert|3|cm|in|frac=4}} long by {{convert|2|cm|in|frac=5}} wide.[6]The Latin specific epithet rivale means “growing by streams”, with reference to a preferred habitat.[7] Under its former name, Trillium rivale, this plant has gained the Royal Horticultural Society's Award of Garden Merit.[8][9] References1. ^{{PLANTS|id=TRRI2|taxon=Trillium rivale|accessdate=15 December 2015}} 2. ^Farmer, S.
