This yellow flag cultivar is a rhizomatous perennial iris which grows in expanding clumps to 2-4� (occasionally to 5�) tall. Plant height is directly proportional to the amount of soil moisture. Spring is the peak ornamental time for this plant: newly emerging, sword-shaped, linear, green leaves are variegated with bright yellow striping and yellow irises (2-5� across) with brown markings on the falls bloom on rigid, upright scapes. Leaf variegation tends to fade by summer. (http://www.missouribotanicalgarden.org/)
