The 200 species of iris can be divided into two groups. The first
has creeping, underground stems, or rhizomes and includes the bearded (or
German) irises and the Japanese and Siberian (beardless) irises. The second
group has bulbs, modified underground buds with fleshy leaf bases and includes
the Dutch, Spanish, and English varieties.
The beard in bearded irises
consists of a group of colored hairs on the upper surface of each of the falls.
The flowers are composed of a floral envelope (perianth) with six petal-like
segments, three or six stamens, and an ovary enclosed by the base of the
perianth. Triggered mainly by the shortening periods of darkness during spring
and summer, flower buds open to display brightly-colored petals that attract
insects seeking nectar. Once a flower has been pollinated, its petals shrivel
and drop off.
Aside from its horticultural value, the iris family is of
little economic importance. Rhizomes of several species, are dried and powdered
to obtain orris root, used in perfume and other cosmetics.
