The tall, beautiful iris, named after the Greek goddess who rode rainbows, comes in many magical colors.
There are some 300 species in the genus Iris. The most familiar irises are the tall (at least 28 inches) bearded irises (Iris germanica).
The distinctive flowers have three large outer petals called “falls” and three inner upright petals called “standards.” The falls may have beards or crests. Bearded iris are so-called because they have soft hairs along the center of the falls. In crested iris, the hairs form a comb or ridge.
Most irises flower in early summer. Some, mostly bearded hybrids, are remontant, flowering again later in the summer.
