As with other Pacific Coast Hybrid Iris it is best to plant this Iris in a light acidic soil in full sun (coastal only), light shade, morning or late afternoon shade and water sparingly in coastal areas and more regularly inland. Plants are hardy to 15-20 degrees F or slightly lower for short duration. Transplanting or dividing and replanting should be done in December. In heavy alkaline conditions that are often found in southern California soils the addition of peat moss or soil sulfur is recommended, and with very heavy soils applications of gypsum can be beneficial. For more information see the Society for Pacific Coast Native Iris.

The Pacific Coast Hybrid Iris are a diverse group of plant derived from various California and Oregon native species, in particular Iris douglasiana, Iris innominata, and Iris munzii. They are noted for their attractive clumps of foliage that usually are under a foot tall with leaves that are usually dark green and shiny and large showy flowers ranging in color from white, yellow, red and blue with nearly all shades between that are held one to two per flowering stem in spring. We have grown many varieties over the years and sometimes offer them in blocks of mixed colors.
