Gerald Darby Siberian Iris (Iris x robusta 'Gerald Darby')....purple at base of leaves....small violet flowers splashed with yellow.
(zones 5 to 9). Are these colors for real? Slim variegated leaves cascade down the length of the 3-foot stems in a rainbow of colors — dark green to yellow to red. During the cooler months of spring and fall, the leaves become especially ornamental, blushing even more vibrant shades of pink. Spring also brings the flowers — a cluster of chartreuse cyathiums with only the slightest glimpse of red. And while this particular plant flowers in spring and summer, its prismatic foliage is evergreen.
