Our Native Irises: Pacific Coast Irises
Iris chrysophylla: Yellowleaf Iris
The yellowleaf iris occurs from northern California into western Oregon.
Iris chrysophylla flowers are creamy white or a very pale yellow. The sepals are moderately upright and then arching downward with prominent deep yellow, lavender or purple veins. The signal is a yellow patch surrounded by the veins. The petals are upright and slightly spreading, shorter and narrower than the sepals. The inflorescence has one to two flowers. The flowering stalk can be shorter or longer than the attending leaves. The light green leaves are upright, slightly reflexed, and basal with a pink to reddish base, from rhizomes with few roots occurring in small clumps.
Iris chrysophylla is commonly found growing in open coniferous forest.
