- Description
-
The dwarf iris is a bulbous perennial herb in the Iridacea (iris) family native to eastern Europe which blooms very early in the spring. It is only 4 to 6 inches high and 4 inches wide. The genus name Iris is shared by the Greek goddess of the rainbow, and is perhaps a nod to the wide variety of colors of flowers found in this genus.
This iris grows best in morning sun to full sun in average, well-drained soil with moisture supplied during the growing season. It is drought-tolerant and should be allowed to dry in the summer to set buds for the next spring bloom. It reproduces best by division. The reticulate patterned bulb divides into bulblets (offshoots) after blooms have faded and may be separated and replanted at 5 inches deep, but may take several years to mature. If the number of blooms is decreasing, it is recommended to separate and plant these bulblets or treat this iris as an annual by planting additional bulbs every fall.
The small, fragrant flowers are a vibrant blue to violet or white. The leaves are fine and grasslike at only the height of the flowers at bloom, 6 to 8 inches, and rise to 12 to 15 inches after the flowers fade. The leaves disappear during the summer dormancy. Once established dwarf iris is drought tolerant and it is resistant to browsing by deer.
Dwarf iris is impressive in a mass planting at the edge of a border, along walkways, in beds, containers, and rock gardens. It is also excellent for use in woodland gardens or near ponds and streams when naturalizing. Group them in small spaces like courtyard gardens, along patios or walkways. Consider planting these purple blooming beauties in a cutting garden where the blooms can be enjoyed both indoors and out.
Insects, Diseases, and Other Plant Problems: It is less susceptible to the fungal, bacterial, and iris borer problems of other iris.
