Slightly invasive in a bed but easy to remove. This yarrow will grow anywhere it is placed, in any soil or light in my zone 4 garden. There is some flowering in the sand under my porch right now. It's difficult not to appreciate such a hardy perennial.
Region: Lower Plains
One original plant has spread to a bed of approx. 5 x 8 feet, filling in a space under a pine tree where nothing else will grow. Though it is aggressive in spreading, it has not invaded my lawn grass. It requires only occasional watering; more in the heat of summer (it averages 90-100 here, with humidity levels of less than 15%). The fine, ferny leaves are a beautiful ground cover, and are long lasting in cut flower arrangements. My plants bloom white, though sparsely, as they are in shade. The foliage remains green throughout winter with adequate water.
