Pycnanthemum pilosum (Hairy Mountain Mint) - Plugs$8.95
Hairy mountain mint is an attractive prairie and open meadow wildflower native to the Lower Midwest, most commonly ranging from Missouri to Indiana with outlying populations in Tennessee, Georgia and the East Coast.
Hairy mountain mint forms an attractive mound of strongly peppermint-scented leaves and 1" white button-shaped flowers from June through August. Hairy mountain mint grows mostly in dry to medium loamy soils in the Tallgrass Prairie Region, occasionally making it into open woodlands on upland sites.
Hairy mountain mint spreads by rhizomes (though not nearly as aggressively as common mint, Mentha spp.) and over time can form large clumps.
Hairy mountain mint is one of the more attractive mountain mints, with billowy white blooms on medium-height clumps of deep green foliage. This mountain mint survives torrential rainfall and hot, dry weather unfazed, and reliably comes back year after year, even seeding around a bit.
Hairy mountain mint is particularly favored by pollinators such as bees, wasps and flies - We have seen more species of wasps on our patches of Hairy Mountain Mint in the nursery more than any other native wildflower!
How to Grow
Hairy mountain mint is very easy to grow. Place them 18-24 inches apart at the back of perennial beds, or intersperse meadow and prairie plantings with them. Hairy mountain mint will adapt to most soils, ranging from moist, rich soils to dry and sandy/rocky soils. As usual, growth and flowering will be much better in richer soils. Hairy mountain mint does best in full sun, though we have several patches in shady spots that only receive sun in the morning, and they do fine.
For best flowering and form, cut back the plants by half when they are about 2 feet tall, and they will form a much more densly-branched, tight cushion of flowers. Untrimmed plants tend to get a bit tall and leggy.
Our Hairy Mountain Mint are grown in 2.25" RootMaker Plugs, and will establish and bloom within one growing season. Many of our native plants we grow are host plants for butterflies and pollinators, so we keep pesticide use to a minimum and use no neonicotinids in our nursery.
