Iris pallida 'Aureovariegata'
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.
