Ruffled Velvet Siberian Iris (Iris sibirica ‘Ruffled Velvet’)
Siberian iris blooms in late spring and early summer in many hues including purple, pink, yellow and white. Foliage forms a mound with a grassy texture. Siberian iris doesn’t typically need dividing for five to 10 years after planting. Divide clumps that show diminished growth or smaller blooms. You can also divide to multiply plants. Divide plants in early spring as growth begins or before your region’s rainy season. Plants are hardy in Zones 3 to 8.
