Iris cristata
A low-growing, rapidly spreading plant that typically grows 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. It typically occurs on rocky, wooded slopes, on bluffs and along streams. When in flower, a well-developed bed can produce a spectacular drift of blue color.
