Bearded Irises come from species originating in central Europe and the Middle East.
There are the pure original species and the modern hybrids
The modern hybrids are the most common and are classified on the basis of flowering height.
DWARF
BEARDED IRIS under 16inches (35cm)
These are further categorized as Miniature Dwarf Bearded (under 8 inches) and Standard Dwarf Bearded (8-16 inches)
These are highly floriferous and form delightful flower carpets. They are easy to grow but do require full sun and frosty winters and loose well-drained soil. Do not allow to dry out totally, over summer.
MEDIAN BEARDED IRIS 16-27 inches (35cm - 87cm )
Border Bearded (BB)
are shorter growing tall bearded and require
similar conditions.
Intermediate Irises (IB)
are crosses between dwarf and tall bearded
and require a bit more cooling and a bit more watering than tall bearded.
ArilBred Irises (AB)
are tall beardeds crossed with
Aril (Desert)
irises. They like very well drained soil and may die down in summer.
Minature Tall Bearded
are often sometimes called table iris because they are very dainty and
suitable for small arrangements. Similar growing conditions to other bearded
iris.
TALL BEARDED IRIS over 87cm
Like neutral to alkaline well-drained soils in full sun, cool to cold winters and hot summers. They are extremely hardy and require only light watering throughout summer. They appreciate a good slow release fertilizer or organic fertilizer, but do not place water-holding mulch directly on top of the rhizomes or they may rot.
They are best divided soon after flowering (Nov-Dec) or late summer (Mar-May), but they will survive being moved almost any time. However, if you must move then in Jan-Feb, be careful not to over water and induce rot.
They are best grown where they get full summer sun, but in very hot areas they may benefit from some afternoon shade, especially the rich dark colours.
The Bearded Irises come in a wide range of colours and patterns
