Try an The most common garden Irises are the german bearded Irises, Siberian Irises, and the Japanese Irises. Most of the irises you buy will be cultivars of species from one of these three categories. The Iris is a striking plant with a unique bloom shape–one of the most readily identifiable flowers in any garden. Most iris will be some shade of blue or purple, adding a very cool feel to your garden. Many spring flowers have overtly warm tones, yellows and reds, but irises make a nice contrast.
The bearded irises are easy to cultivate and propagate, and have become very popular in gardens. They grow in any good free garden soil, the smaller and more delicate species needing just a little organic material, either peat or loam, for better drainage. The Japanese and Siberian Irises do well in very moist soil, some varieties even work well as water plants. If planted this fall, your iris bulbs or rhisomes will become well established over the winter and give a great performance next spring.
