Easily grown in average, consistently moist, well-drained soils in full sun to part shade. Soils should be moist during the spring growing/blooming season, but needs to become relatively dry during the summer dormant season in order for the bulbs to set buds for the following year. Planting bulbs in a gritty soil on a slope helps meet the changing soil moisture requirements. Plant bulbs 3-4” deep and space 3-4” apart in fall. Bulbs tend to separate into offsets or bulblets after bloom (particularly when planted shallowly), with each new bulblet requiring several years to mature. Although bulbs can be dug and divided (offsets removed) after bloom, it is probably best to do this only if flowering has significantly declined. In order to insure consistent flowering from year to year, it is an option to plant supplemental bulbs each fall, or to grow this plant as an annual by planting new bulbs each fall.

Noteworthy Characteristics

The reticulated iris group consists of a number of small bulbous irises whose bulbs have netted or reticulate bulb coverings (tunics) on the dry bulbs. All species of reticulated iris are native to western Asia (Turkey, Caucasus, Lebanon, northern Iraq and Iran). Leaves are gray-green with square to cylindrical cross sections. Flowers appear in early spring, with plants going dormant by late spring. Iris reticulata and Iris danfordiae are perhaps the two most commonly known species in the reticulated group.

Genus named for the Greek goddess of the rainbow.

'Pixie' is a low-growing, reticulate or netted iris that blooms in March to early April in the St. Louis area at about the same time as snowdrops (Galanthus), glory-of-the-snow (Chionodoxa) and the early crocuses appear. Slightly fragrant, deep violet-purple flowers (to 2.5" diameter) with bright yellow crests on the falls bloom on naked stems (scapes) typically growing to only 4" tall. Narrow, grass-like leaves elongate to 15” after bloom, but eventually disappear by late spring as the plants go dormant. 'Pixie' is sometimes sold in commerce as a cultivar of Iris reticulata. It is a sport of Iris 'Harmony'.


No serious insect or disease problems. Fusarium basal rot is an infrequently occurring disease problem. Watch for slugs and snails.


Best massed in sunny areas of rock gardens, border fronts, along walks or along streams or ponds. Best planted in mass. Small groups of this diminutive iris can get lost in the landscape. Also may be forced in pots.
