Iris PCH 'Ivory Queen' (Pacific Coast Hybrid Iris) - This Pacific Coast Hybrid Iris has ivory-white colored flowers marked with yellow and purple veins. The clumps of tough evergreen foliage grow to 12 to 18 inches tall and spread to 2 to 3 feet wide. Flowers in spring. 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.
