Plant Taxonomy of Iris Reticulata:
Plant Type for Iris Reticulata:
Characteristics of Iris Reticulata:
The flowers of this dwarf are tricolored (bluish-purple, yellow, white), but the purple color is dominant enough for us to classify them as purple flowers (the yellow and white can be considered accents). The grassy foliage on mine reaches 9 inches during the blooming period (over 1 foot afterwards), but the flowers stand, at most, about 7 inches off the ground. The width of the plant is initially much less than the height, but an Iris reticulata often spreads via offsets over time.
Sun and Soil Requirements:
Care for Iris Reticulata:
Fertilize with a bulb fertilizer after blooming is done.
To rejuvenate a patch of Iris reticulata that has evidently petered out over the years, divide and replant the offsets after the plant finishes blooming (some do so immediately, in spring; others wait till fall). By summer, the leaves will die back as the plant becomes dormant. Allow this die-back to occur naturally, rather than "helping it out" by removing leaves prematurely: the plant is taking in and storing nutrients as long as the foliage is green. It is also important that the bulbs be resting in dry soil during their period of summer dormancy.
Summary on Iris Reticulata: Early Blooming but Early Exiting:
This dwarf is one of the earliest bloomers in spring. Its tricolored flowers exhibit a design that is fun to study on warm days in early spring, when you're looking for an excuse to spend time outdoors. I also marvel at beauty of the unopened flowers of my 'Harmony', just before the petals unfurl: long, narrow and tapering to a point, they are a dark purple lined with golden-yellow stripes and remind me of exquisitely decorated, miniature spearheads.
A drawback of this plant is its proclivity to peter out relatively quickly. I'm lazy about bulb plantings and tend just to let them "do their own thing" for years, accepting the fact that I will be overseeing (in some cases) a gradual decline. But the decline of Iris reticulata 'Harmony' is not gradual, in my experience. You will need to divide them and/or buy additional stock every few years to maintain anything like a peak display.
Meaning of the Name, Iris Reticulata:
The genus name comes from the Greek. It was the name of the Greek goddess of the rainbow and messenger to the gods (the female counterpart of Hermes, or "Mercury"). This derivation apparently pays tribute to the very colorful flowers borne by the various types of irises that grace our gardens (as in "the colors of the rainbow").
Meanwhile the species name, reticulata, means "netted" or "reticulated," a reference to the netted pattern that can be discerned on the plants' bulbs.
