What are the three types of iris?
Classifications. The American Iris Society divides irises into three main classifications: Bearded, Aril, and Beardless Irises. In general, the Bearded and Siberian varieties are the most suitable irises for Connecticut gardens. The Siberian Iris has some of the most eye-catching blossoms and stands out in sunny flower gardens or near water features. The beardless blooms are available in a variety of color combinations and have the traditional iris flower shape of three upright petals and three falling petals.Irises require at least a half-day (6-8 hours) of direct sunlight. Some afternoon shade is beneficial in extremely hot climates, but in general irises do best in full sun. Iris will grow in deep shade, but probably not flower.
