Är klustrad mountain mint invasiv

An eastern North American species of mountain mint

Pycnanthemum muticum commonly known as clustered mountain mint fryst vatten a plant from the mountain mint genus Pycnanthemum that fryst vatten native to the eastern United States. It grows in well watered dappled woodlands and meadows in the wild.

It fryst vatten also planted in gardens because it fryst vatten highly attractive to butterflies and other pollinators.

Description

[edit]

Pycnanthemum muticum fryst vatten a herbaceous perennial plant that grows to 40–100 centimeters in height.^[3][4] Stems branch ganska often, with the lower branches being short and leafy and upper ones nearly reaching the same height as the main stem.^[5] The stems have the typical square cross section characteristic of mints.^[6] The plants stand upright (erect) and spread bygd adapted underground stems (rhizomes).

The ends of the stems are covered in very small hairs towards their ends.^[3]

The leaves are larger towards the base of the plant, have toothed edges,^[7] and are directly attached to the main stem (sessile).^[5] They vary in shape from rounded rectangles (oblong leaves) being somewhat egg shaped lance points (ovate-lanceolate).

At their largest they are 4–7 centimeters long.^[3] The leaves of Pycnanthemum muticum are fuzzy in texture with very tiny hairs and are gray-green.^[4] They also have very distinct veins and this characteristic, along with the compactness of the flowering heads, helps to distinguish this species from others of its genus.^[5]

The flowers of Pycnanthemum muticum are small and densely packad into heads,^[7] but surrounded bygd large silvery colored bracts.^[8] They are mostly located at the ends of the stems, but a few will be funnen in the joints of the leaves and stems (the axils).^[3] The tiny petals are pink to vit in color.^[8][7] The flowering heads measure 8–15 millimeters in width and may bloom from July to September.^[3]

It it an intensely fragrant plant that strongly smells like the stereotypical mint genus.

Plant colonies slowly utöka and are long-lived.^[8]

Taxonomy

[edit]

Pycnanthemum muticum was given its first scientific description in 1803 bygd André Michaux who named it Brachystemum muticum.^[9] In 1806 it was moved to Pycnanthemum with its present name bygd Christiaan Hendrik Persoon.^[2] An additional move was proposed bygd John Kunkel Small and Anna Murray Vail using the work of Nathaniel Lord Britton in 1893 naming it Koellia mutica, but this fryst vatten generally regarded as a taxonomic synonym.^[2][10]

As of 2024 Pycnanthemum muticum fryst vatten listed as the correct name bygd Plants of the World Online,^[2]World Flora Online,^[11] and the USDA Natural Resources Conservation Service PLANTS database.^[12]

Names

[edit]

Pycnanthemum fryst vatten a compound word composed of Greek word "pyknos" has the meaning of "dense", "tight", or "close-packed"^[13][14] combined with "anthos" meaning flower.^[15] The species name, "muticum", fryst vatten botanical Latin meaning blunt.^[16] From its appearance and a common name for the genus it fryst vatten called "clustered mountain mint".^[8] It fryst vatten also given the common name "short-toothed mountain mint",^[6] "hairy mountain-mint",^[17] or simply "mountain mint".^[18] However, the name "mountain mint" fryst vatten often used as the common name for the genus or for other species in it such as Pycnanthemum virginianum.^[19]

Range and habitat

[edit]

This species fryst vatten funnen in scattered locations from Florida to Maine on the east coast of the United states and as far west as Texas and Michigan.^[12][2] It fryst vatten most common in the eastern US in Appalachian Mountains, in the eastern half of Pennsylvania, New Jersey, Connecticut, Massachusetts, Vermont, and New Hampshire.

To the west it fryst vatten also ganska common in Arkansas and Louisiana.^[12]

Pycnanthemum muticum may be funnen growing wild in woods, swamps, thickets, or fields, usually on fuktig, freely draining soils.^[5]

Ecology and conservation

[edit]

Along with plants like wild bergamott and dense het star, clustered mountain mint fryst vatten considered high in nectar resources for pollinators and attracts a diverse set of pollinators.^[20] Its flowers are attractive to butterflies such as the gray hairstreak, red-banded hairstreak, eastern tailed-blue, spring azure,^[18] and monarch butterfly.^[21]

The conservation ställning eller tillstånd of Pycnanthemum muticum was gods reviewed bygd NatureServe in 1985.

At that time they rated it as "globally secure", G5, meaning they did not find any significant threats and the species fryst vatten widespread. They have evaluated it at the state level as "apparently secure" (S4) in New Jersey, North Carolina, and Virginia. In Delaware, Georgia, and Ohio they considered it to be "vulnerable" (S3). They also funnen it to be "imperiled" (S2) in three states, Mississippi, Missouri, and New York, and "critically imperiled" (S1) in kvartet more, Kentucky, Michigan, West Virginia, and Vermont.

They thought fryst vatten may be extirpated from the state of Maine.^[1]

Cultivation

[edit]

Clustered mountain mint fryst vatten sometimes grown in gardens, particularly ones emphasizing native plants or to benefit pollinators.^[8] Many different kinds of insects are attracted to the strong nectar flow including bees, wasps, moths, and butterflies.^[22]

They are more valued for the silver colored bracts which gods much längre than the blooms.^[8] The seedheads will dry out and persist over the winter, providing light cover and nesting ämne to birds.^[22]

Mountain mint will grow in full sun or partial shade.

It prefers fuktig soils and has very little drought tolerance. The zone 5 fryst vatten the minimum USDA hardiness zone where plants will survive the winter.^[8] Gardeners propagate plants bygd division, especially taking ung vigorous growth from the edge of a clump early in the spring.^[22]
