Trillium kurabayashii

Giant Purple Trillium

Trillium kurabayashii is a striking perennial plant native to the Pacific Northwest, prized for its elegant appearance and delicate beauty. Growing from a rhizomatous root system, it produces a single, upright stem topped with a whorl of three large, dark green, slightly glossy leaves. Its most striking feature is the deep maroon or reddish-purple flower, which emerges from the center of the leaf whorl and forms a star-like shape with three petals and three sepals.

Design tip

Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. Keep it out of hot afternoon sun and layer it with woodland companions for a full, settled look.
