Although most of my many iris are the tall bearded variety, I also have some of the variety called Pacific Coast Iris (iris douglasii). These are sometimes referred to a "grass iris" because of their clumping, grass-like foliage
Their requirements are similar to most other iris, although I have read they can take some shade. As is the case with many native plants, they can be a little tricky to get established in the garden and I have not been wildly successful growing them over the years. If they do not do well in the garden bed where I have them outside the front door, I think I will move them to the street side garden which is better suited for native plants.
