Our Native Irises: Dwarf Woodland Irises
Iris tenuis: Clackamas Iris
The Clackamas iris occurs in the Clackamas valley in Oregon.
Iris tenuis is a very light pale blue spring wildflower occasionally white. The signal is composed of a series of pale yellow ridges on the spreading sepals. The petals are ascending. The inflorescence has two to three branches with each branch possessing a single flower. The 15 mm wide, stiff dark green leaves arise from shallowly rooted creeping rhizomes, 30cm between offshoots forming loose colonies.
Iris tenuis is commonly found growing in leafy organic soils, in sunny openings in Douglas fir forest.
