Also known as the Zebra Iris, this is a very old garden plant, still as popular as ever. It forms a low clump of sword-like leaves, with golden-yellow and grey-green stripes running lengthwise, remaining nearly evergreen in mild winter regions. Fragrant lavender-blue flowers appear in early summer. Excellent for cutting. Plants must have excellent drainage, particularly in hot, humid summer regions or areas with wet winters. Clumps may be easily divided every 3 to 4 years in late summer, exactly as you would treat a Bearded Iris.
