This cultivar of Iris cristata is a dwarf crested low-growing, at 3-6 inches tall, native Iris which spreads quickly. Small white flowers with yellow-crested falls, rather than blue, are a bright addition to a dark, shady, naturalized area. Multiplying to a dense growth in conditions of rich, well-drained soil, it can create a woodland floor of color in early spring and a good groundcover through the summer. It can tolerate marshes and even shallow water, in partial to full shade. It can be planted from seed or rhizomes can be divided in the fall to propagate. Its narrow, yellowish-green leaves are shorter than standard Iris but retain the knife-edge shape. Insects, Diseases, and Other Plant Problems: More information on Iris cristata .
