Iris PCH 'Canyon Snow' (Pacific Coast Hybrid Iris) - Iris 'Canyon Snow is a Pacific Coast Hybrid Iris that was introduced into the nursery trade in 1975 by the Santa Barbara Botanic Garden. It was hybridized by the late Dara Emery (1922-1992), the legendary horticulturist, plant breeder and author who had a 35-year tenure as "The Horticulturist" at the Santa Barbara Botanic Garden. In 1979 Dara received the prestigious Mitchell Award from the American Iris Society for this beautiful hybrid Iris. The narrow dark green leaves of this cultivar rise to 12 to 18 inches in a clump to 2 to 3 feet wide. In spring emerge the large flowers, which are white with bright yellow central markings on each petal. Iris 'Canyon Snow' is also noted for its vigor and bright glossy green foliage. As with other Pacific Coast Hybrid Iris, plant 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 gypsum is added. We received comment on this plant from a gardener in Seattle Washington who had grown it for over seven years in his garden and noted that it "blooms reliably every year and increased to nearly a ground cover. Never any fungal problems or winter burnt out like with other PCH iris I have tried. It's a winner!!" More information on this plant can be found on the Santa Barbara Botanic Garden's Plant Introduction Page Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Iris PCH 'Canyon Snow'.
