The parts of the iris
flower occur in groups of three. The sepals,
or outer 3 parts of the flower, are the
falling petals called the falls, which
usually droop. The petal-like part of the
fall is called the blade, the basal part is
the haft. The inner parts, or upright
petals, are called standards. Inside these
are 3 more petal-like and very narrow organs
called style arms.
There are many categories
of iris, however, the most common ones in
the landscape include four broad groups.
(also called pogons) have a fuzzy, often bright
colored "beard" on each falling petal
(also called apogons) are
lacking this feature.
Crested Iris have a distinctive ridge or
"crest" on the fall.
Bulbous Iris do not have a
the others but rather survive as a bulb.
The iris is named for the Greek goddess of
the rainbow. Many species are called "flags"
because the sepals of the flowers hang out
