Alaska Iris Field• From Wikipedia: Irises are extensively grown as ornamental plants in gardens. The most commonly found garden iris is the bearded German Iris and its numerous cultivars. Various wild forms and naturally occurring hybrids of Iris pallida and I. variegata form the basis of most all modern hybrid bearded iris. Median forms of bearded iris [intermediate bearded (IB), miniature tall bearded (MTB), etc] are derived from crosses between tall and dwarf varieties. Other iris types commonly found in garden are I. siberica and its hybrids (Siberian irises) and I. ensata and its hybrids (Japanese irises).
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 only the aid of turf ingredients, either peat or loam, to keep it light and open in texture. The earliest to bloom are the dwarf forms of Iris pumila, which blossom during March, April and May; and during the latter month and the following one most of the larger growing 'tall bearded' varieties, such as I. germanica, florentina, pallida, variegata, amoena, flavescens, sambucina, neglecta, ruthenica and their modern hybrids.
A true red standard, tall bearded Iris remains an unattained goal of frequent hybridizing and selection. There are species and selections thereof, most notably Iris fulva, which has a relatively pure red color. However, getting this color into a modern Iris breed has proven very difficult, and thus, the vast majority of Irises are in the purple and blue range of the color spectrum.
