From Michigan Bulb Co.
Dutch hybrids (I. hollandica): These irises—also called Beauty Irises—are perfect for cutting gardens. Often grown as annuals, Dutch iris hybrids grow from bulbs that can be planted in fall (where hardy, zones 5 to 9) or spring. Orchid-like flowers bloom from late spring to early summer. This group of irises has an especially wide range of colors and patterns. Unlike the foliage on other types of irises, these hybrids have grass-like leaves.
Plant in full sun to full shade, 4 inches deep. Tip: Zone 5 gardeners should add a 2-inch layer of mulch in fall.
