Dwarf Irises bloom at the same time as mid-season tulips and late narcissus. They rival bearded Irises in their color range, but grow only a few inches tall. Their cultural requirements are the same as the taller irises, they only require full sunlight and good drainage to thrive.

They spread very rapidly, and can be divided six weeks after blooming. Each individual rhizome will make a new plant, and should be planted with the top half of the rhizome above ground; dig little trenches on either side for the roots.
