Pacific Coast Iris
A group of native iris species and hybrids from the Pacific coast forming clumps of narrow evergreen foliage. Flowers range through blues, purples, yellows, and whites, often with intricate veining patterns. Plants spread gradually by rhizomes and adapt to Pacific Northwest conditions.
Prefer well-drained soil with some summer moisture. Native to coastal regions from British Columbia to California. The evergreen foliage provides year-round interest. More drought-tolerant than bearded iris once established. Excellent for naturalistic plantings and native gardens. Move immediately after flowering for best results.
