While exploring trails and State wildlife preserves in my local area several years ago, I found a wild population of Iris tenax, our local species in the Pacific Coast Iris family. I'd seen this species in the area before, but it was always in open grasslands and prairie preserves. Clumps of irises were growing along a shaded maintenance road and in open spaces with higher moisture content than open prairie lands provide.
Beside the road I. tenax seemed to be happily growing with little direct sunlight and competing with woodland. The clumps were open and not as dense as those found in full sun. Stalks tended to be more vertical and less arching.
The foliage was narrow and grass-like.
The blooms ranged in shade from lighter to darker in tones of orchid pink thru lavender, often with yellow signal markings and lighter fall lines. I caught a white clump blooming once but have not seen it since.
The flowers had flaring petals and enough waving on the falls to make the tips appear pointed. Quite a charming wildflower.
Further down the road the area opens out a bit and the woods recede to the edges of the clearing where homes once stood. I am guessing they housed people working at the munitions factories in the area during the great wars of the early 20th century. Both homes and factories are long gone, but remnants of them can be found if you keep a sharp eye out.
The open areas are mowed every few years to keep the invasive Scotch broom down. This doesn't seem to harm the irises.
Some have deeper more intense colors to catch the eye.
