Comments:
This western iris produces bright blue to purple flowers, rarely white. Dark purple veins are quite prominent in the flowers. It is somewhat short-lived compared to other species. Performs quite well in a wide range of soil conditions from moist to roderately dry. Moderately stiff, bright green leaves can grow to nearly three feet tall and have a whitish color at the base.
