- Description
-
Blunt mountain mint is a native, herbaceous perennial, wildflower in the mint family (Lamiaceae). It is native to eastern Canada and eastern United States. The species epithet is Latin for “blunt,” and refers to the shape of the bracts below the flowers. They are not exactly "blunt," but they are less pointed than those of other species.
Blunt mountain mint grows in full sun to partial shade and in moist soil with good drainage. It grows 3 to 4 feet tall in a space of 2 to 3 feet. Although blunt mountain mint is not considered invasive, it is a vigorous grower, spreading its rhizomes, in optimum conditions. If spreading is not needed or wanted, the roots should be pruned in the spring with a spade.
The leaves emit a strong spearmint fragrance when crushed. The leaves and flowers may be used for tea.The flowers attract butterflies and other pollinators.
It is commonly found in woodland areas and thickets. The best landscape uses include butterfly, edible, native, pollinator and rain gardens.
Insects, Diseases and Other Plant Problems: No serious insect or disease problems. Plant is weedy.
