|One of the most spectacular of all Irises, their 5- to 9-inch-wide flowers bloom in purple, pink, white and blue, often marked with a contrasting color. The 2- to 3-foot-tall stems each produce 3 to 15 single, double or peony-like flowers in early to mid-summer. Will not tolerate hot, dry climates. Thrive with lots of moisture and rich, organic soil. Ideal in groups near ponds or in pots submerged in water. Plant divisions in spring. Feed heavily with high nitrogen during growing season for maximum-sized blooms. Divide and replant every 3 to 4 years.
Hybrids of a Southeastern United States native, they come in many heights and colors -- brick red, lavenders, blues, and bicolored white and purple. Grows equally well in wet waterside soils or well-watered garden beds.
