Narrow-leaved mountain mint (Pycnanthemum tenuifolium), also known as slender or narrowleaf mountain mint, grows in dense clumps to about 2 feet tall, with an abundance of intensely mint-scented, medium green, almost needle-like foliage. Showy clusters of small white flowers appear at the stem tips through most of the summer, much to the delight of bees, butterflies, and other pollinators. Because it tends to stay in distinct clumps, this species is a great choice if you want to add a mountain mint to a small bed or border. Plant a few extra for cut flowers, too: It’s like a mint-scented baby’s breath (Gypsophila)!
Narrow-leaved mountain mint is native to eastern North America. I collected these seeds from plants that grow wild in my Bucks County, PA, meadow, where P. muticum and P. virginianum also grow. I’m not sure how likely they are to cross, but in the interest of full disclosure, please be aware that there might be some possibility of natural hybridization. Full sun. Perennial; Zones 4 to 8.
Collected starting in late September 2022. At least 30 seeds. PA ecotype.
Please read the germination information as well before ordering.
