iris

Of the fifteen or so Iris that are native to the whole of the west coast, seven are at home here in Oregon. Most grow in colorful drifts in primarily open wooded areas at low elevations west of the Cascades.

The flowers, rising gracefully above the foliage on slender stems, wear colors ranging from deep bluish purple to lavender to yellow to white (or varying combinations of these), generally with dark purple veining. Iris freely cross-pollinates in areas where two or more species grow adjacent to each other and naturally-occurring hybrids occur.

Iris tenuis: Clackamas Iris

The Clackamas Iris is only example of a “crested” Iris in the western US, Iris tenuis is only found sporadically along the Clackamas and Molalla rivers in western Oregon, and in sporadic patches near Mt. Hood. This dwarf Iris blooms light blue to white, with light purple veins and yellow ridges on the sepals.

Iris tenax: Oregon Iris

.

Pacific Coast Iris Hybrids – In the wild many of the native Iris species growing in the same area will cross-pollinate and naturally hybridize. Some of these combinations result in beautiful color variations and combinations. Naturally-occurring hybrids can sometimes be found in nurseries, and are often of unknown color until blooming. 

Named selections of Pacific Coast Hybrids have been chosen and propagated for predictable color.
