This herbaceous perennial spreads by means of underground rhizomes. Flowering stems are up to 55 cm tall, with purple or maroon flowers. A yellow-flowered form devoid of purple pigments is also known.[7] Fresh flowers usually have a spicy odor.[8]

Some authorities consider Trillium kurabayashii to be a synonym for Trillium angustipetalum.[9] Observing that the former has much wider petals than the latter, Freeman considered them to be distinct species.[6]
