Oregon Iris

Iris tenax

Plant Description

Oregon iris is a rhizomatous perennial native to open grasslands, rocky slopes, and forest edges of the Pacific Northwest. It is recognized for its stiff, narrow, sword-like leaves and striking blue to violet to yellow flowers that bloom in late spring, often with darker veins and yellow or white nectar guides. This species is highly drought-tolerant and adapted to well-drained soils, making it resilient in dry, sunny habitats, and an excellent addition to gardens where it can form a groundcover. Ecologically, Oregon iris provides early-season nectar for hummingbirds, bees, and other pollinators and contributes to the structural diversity and aesthetic value of native grassland and woodland understories. The tough leaves were traditionally used for rope-making.
