Pycnanthemum muticumAlso known as:
big leaf mountain mint
Pycnanthemum muticum is a compact, dense-growing, attractive member of the Mint family, that typically grows to a height of 3'. The leaves are deep-green, heart-shaped, and produce a strong spearmint aroma when crushed. The individual pinkish-white flowers are tiny, but form dense button-like clusters about 1" in diameter. The base of each cluster sports 2 large, silvery, leafy bracts that will give the plant an overall grayish appearance when in full bloom.
Pycnanthemum muticum is very easy to grow in average, moist to dry soils, in full sun to filtered light. Under ideal conditions it will spread vigorously, but is not as aggressive as exotic members of the Mint family. It should be placed in an area where it will have ample room to romp. Unwanted growth can be easily pulled in early spring. Its dense habit and silvery appearance make it a great accent plant when grown in a perennial flower garden. It is a profuse bloomer from July to September. Zones 5-8
Propagate by seed in fall, or by division in early spring.
Pycnanthemum muticum is an exceptional species for attracting pollinators.
