Rainy Side Notes
Sisyrinchium is a small and dainty iris relative. This northwest native thrives close to a planting of Iris siberica 'Caesar's Brother' next to the dry bed stream in my back garden. It self seeds so well, some people may think it is a weed. For a wet spot in the garden this plant will be a good addition.
