Common purple iris varieties include the lilac-colored Variegata, also called the Dalmatian iris, and the purple-black Before the Storm, a fragrant, mid-season bloomer. Other popular purples include the Dusky Challenger and the Purple Sensation.
Purple irises are classified as either bulbous or rhizome irises. Bulbous irises usually produce smaller flowers than the rhizome irises.
Purple irises are widely adaptable and grow well in sunny locations with moist, well-drained soil. They generally thrive in USDA zones 3 to 10.
Purple irises vary in height from as short as 8 inches to as tall as 5 feet. Most iris varieties bloom for two to three weeks in the late spring to early summer.
Purple irises are commonly used for borders in perennial gardens and as container plants. Irises are frequently used as cut flowers in colorful table arrangements.
The purple iris is the state flower of Tennessee. The iris flower was named after the Greek goddess of the rainbow.
