Standard Dwarf Bearded and MDBs

The SDBs are some of the most useful garden plants, ranging in height from 15 cm to 41 cm. They begin flowering as the MDBs are ending, still quite early in the iris season.
Median Dwarf Bearded (MDB) are the smallest of bearded irises, with a height of up to 20 cm. They are also the earliest to bloom. Very easy to grow.
