I’m not talking about those big, beautiful bearded iris (they won’t last here), rather I am thinking of so-called walking iris. True, they are one-day-wonders, but if you have a big patch of them, they will all bloom on the same day, then wait a day, then all bloom again. I have no idea why they do this, but having asked everybody who grows them, I find that every person has the same experience.
Walking iris (Iris) are named for their habit of growing flowers on long stems which eventually get an “air” root system which becomes increasingly heavy. The stem falls over, the root starts to attach to the soil and grow another plant – hence it “walked” to a new location. They are quite “polite” in their spreading habit, and easy to pull out if your patch gets too big. A little morning or mid-day sun and regular water is all they need. These patches also grow pretty densely, so weeds are discouraged from growing except on the edge.
The most common species is Neomarica gracilis. It is white with royal blue accents.
A second type that I have seen a lot is the yellow with brown specks -- Neomarica longifolia.
A third type, and not very common is the sky-blue Neomarica caerulea.
All three can be easily grown in this area. They are pretty cold-hardy, but their leaves can get ratty looking after a freeze (just cut them off). They bloom in late March or early April, and are a welcome sight in your barely awakening garden.
May your horticultural results be as fulfilling as your gardening diligence.
