This dwarf crested iris is a low-growing, rapidly spreading plant that typically grows to 3-6” tall. It features pale blue, lilac or lavender iris flowers with gold crests on the falls. Flowers are borne on very short stems, often appearing nearly stemless. Narrow, sword-shaped, yellowish-green to medium green leaves (to 6” long) arise from a network of branching rhizomes. Spreads quickly and forms dense colonies in optimum growing conditions. Native from Maryland to Oklahoma south to Georgia and Mississippi. In Missouri, it typically occurs on rocky, wooded slopes, on bluffs and along streams in the southeastern Ozark region (Steyermark). When in flower, a well-developed bed can produce a spectacular drift of blue color.
Watch for snails and slugs.
An excellent plant for early spring bloom in a shaded area of the rock garden, perennial border or woodland garden. Foliage forms a nice ground cover for woodland areas.
