Pycnanthemum muticum, mountainmint, is a native perennial that is very easy to grow. It loves full sun to part shade conditions and blooms from July to September.
It spreads through its rhizomes and can be vigorous, but not invasive. You can root prune these in the spring if you want to keep them contained. They grow 2-3’ tall with 2’ spread.
It’s deer resistant and attracts a wide range of native pollinators. This is a great addition to your rain garden, perennial border, cut flower garden, and pollinator garden.
