Like other Mountain Mints, Hoary Mountain Mint is a pollinator favorite; bees, butterflies and moths will be in abundance on your plants. Unlike other Mountain Mints, this one has larger, deeper purple flowers than the traditional small white flowers. The silvery-white foliage is a plus for landscaping and it would make a nice garden companion with bright color, late-summer bloomers like Callirhoe speices or Royal Catchfly. It has a wonderful minty smell.
Pycnanthemum incanum spreads to form small colonies and so is better suited for larger gardens or meadow and prairie plantings than a tidy garden.
