Orchid-like 3-petalled flowers held aloft on stiff stems look much like butterflies on this tough, long-lived, fast and EASY member of the Iris family. Though usually described as a Spring bloomer ours bloomed from Spring thru Fall and beyond here at the nursery in compost enriched soil. Creating a dense 30” x 30” clump, the evergreen, strappy, radiating leaves offer textural and foliar interest in the garden. A nice low maintenance choice for parking strips, that strip next to your driveway and perfect in foreground of roses. Decently draining soil with an annual side-dress of compost for most prolific bloom. Butterflies! Deer resistant!
