Wild yellow flag iris plants (Iris pseudacorus) have started their short blooming period here in our wetter areas. They’re reportedly the only completely yellow, large wild iris now growing naturally in North America.
Although not native to North America, they have become naturalized wildflowers here and are spreading rapidly in Maine and elsewhere, according to the reports that I’ve seen. That’s not good; these handsome little devils are extremely invasive.
The Maine Department of Agriculture, Conservation & Forestry states that they may be controlled with chemicals or by digging them up (wear gloves), bagging them, and disposing of them with the garbage. Note, however, that special rules apply to using herbicides to control plants in or near wetlands and water bodies in Maine. (Images taken in Brooklin, Maine, on June 14, 2022.)
