Satin Flower, Zumwalt Prairie (Olsynium inflatum, member of the Iris family)
Other common names for this beautiful early spring wildflower are Widow Grass
and Blue-eyed Grass. This particular species, with its elegantly pointed petals and
slightly inflated filament, is a close cousin of the O. douglasii. The latter was first
collected for Western science by David Douglas near Celilo Falls on the
Columbia River in 1826.
