Purple loosestrife is a wetland plant that was introduced to the east coast of North America during the 19th century. Loosestrife plants are typically found in poorly drained soils of road right-of-ways and trails, drainage ditches, culverts, lake shores, stream banks, and a variety of wetland habitats. It is a successful colonizer and potential invader of any wet, disturbed site in North America. The plant mass grows on average to be 60-120 cm tall, although some plants may grow over 2 m tall and form crowns of up to 1.5 m in diameter. Purple loosestrife stem tissue develops air spaces … Old fields: On old bottomland fields of the Mississippi and Yazoo rivers, Mississippi, Johnsongrass cover was greatest on silty-clay loams. Populations eventually lead to monocultures. These size and life cycle differences should be taken into account when identifying the plant and choosing a management option specific to your region (Purple Loosestrife BMP). In reality, purple loosestrife is not nearly as destructive to habitats as it’s often made out to be, being more problematic when it colonizes disturbed, fallow habitat than when it exists as a member of an intact ecosystem. donkeys devastate island landscapes via herbivory, leading to soil erosion and habitat loss. During flood events, it can survive by producing aerenchyma – a tissue that allows roots to exchange gases while submerged in water. To dispose of purple loosestrife, put the plants in plastic bags, seal them, and put the bags in the garbage. Flowers: Very showy, deep pink to purple (occasionally light pink, rarely white) flowers are arranged in a dense terminal spike-like flower cluster. Water-loving mammals such as muskrat and beaver prefer cattail marshes over purple loosestrife.

A mature plant may produce up to 2.5 million seeds per year. Purple loosestrife can also alter water levels, severely impacting the significant functions of wetlands such as providing breeding habitat for amphibians and other fauna. Purple loosestrife has square stems, which help to tell it apart from some of the look-alikes that grow in the same areas. Because of purple loosestrife’s ability to adapt to different climates within a short period, the chances are good that it will be very resilient to climate change, expanding its northern range as the climate warms. Once established, however, L. salicaria can exist in a wide range of soil types. Description: When mature (after 3-5 years), purple loosestrife may be over 2 m tall. Fens, marsh and river banks. Habitat: Purple loosestrife was introduced from Europe but is now widely naturalized in wet meadows, river flood-plains, and damp roadsides throughout most of Ontario. Spread, impact, and control of purple loosestrife (Lythrum salicaria) in North American wetlands. Once purple loosestrife (Figure 1)invades a wetland, natural habitat is lost and the productivity of native plant and animal communities is severely reduced. Ecology: Purple loosestrife is a wetland plant, growing in freshwater wet meadows, tidal and non-tidal marshes, river and stream banks, pond edges, reservoirs, and ditches. Marshes, river and creek banks, ditches and wet meadows. Each flower is made up of 5-7 petals, each 7-10 mm long, surrounding a small, yellow centre. By the late 1800s, purple loosestrife had spread throughout the northeastern United States and southeastern Canada, reaching as far north and west as Manitoba. Costs of control, habitat restoration, and economic impact of the continuously expanding purple loosestrife acreage are difficult to quantify. It grows in many habitats with wet soils, including marshes, pond and lakesides, along stream and river banks, and in ditches. The flowering parts are used as medicine. In the 1930s, it became an aggressive invasive in the floodplain pastures of the St. Lawrence River and has steadily expanded its distribution since then, posing a serious threat to native emergent vegetation in shallow-water marshes throughout Ontario. In some places, purple loosestrife stands have replaced 50% of the native species. 3. Purple loosestrife is a wetland plant native to Europe and Asia that was brought to North America the early 19 th century. Habitat Although this plant tolerates a wide variety of soil conditions, its typical habitat includes cattail marshes, sedge meadows, and bogs. For instance, plants in the milkweed family, Asclepiadaceae, (don't let the name intimidate you), secrete a milky sap (except for Butterfly Milkweed) and opposite or sometimes whorled leaves. The Eurasian forb purple loosestrife, Lythrum salicaria, is an erect, branching, perennial that has invaded temperate wetlands throughout North America. Purple loosestrife is a tall, perennial wetland plant with reddish-purple flowers, which may be found in sunny wetlands, wet meadows, river and stream banks, ponds edges, reservoirs, and ditches. Balogh and Bookhout (1989a) report that dense stands of purple loosestrife provide poor waterfowl and muskrat habitat. Habitat. Seeds: Larger plants produce upwards of 2.7 million seeds per growing season. the habitat and then left it fallow. Not only does this decrease the amount of water stored and filtered in the wetland, but thick mats of roots can extend over vast distances, resulting in a reduction in nesting sites, shelter, and food for birds, fish, and wildlife. Purple loosestrife blooms from June until September. It is a successful colonizer and potential invader of any wet, disturbed site in North America. It commonly occurs in freshwater and brackish marshes, along the shores of lakes, ponds and rivers, ditches, and other moist areas. of the Interior, Fish and Wildlife Service. Flowers and leaves. Purple loosestrife has evolved to tolerate the shorter growing season and colder weather of the central and northern parts of the provinces.

The Eurasian forb purple loosestrife, Lythrum salicaria, is an erect, branching, perennial that has invaded temperate wetlands throughout North America. It prefers full sun, but can tolerate shade. There are 5 separate sepals (petal-like leaves) and 5 fused petals. Purple loosestrife has flowers with 5 to 7 purple petals… This highly invasive plant was likely introduced when its seeds were included in soil used as ballast in European sailing ships and discarded in North America. (Purple Loosestrife BMP). U.S. Distribution: Purple loosestrife has been introduced to every state except Florida. I'd call it "vigorous" in the UK, although outside Europe it can be an invasive menace. It can also be found in tidal and non-tidal marshes, stream and river banks, wetlands and on occasion, in fields. Purple loosestrife spreads down river. The stands reduce nutrients and space for native plants and degrade habitat for wildlife. Its long stalks of purple flowers are a common sight in wetlands. Annual Cycle: Purple loosestrife is a perennial that reproduces by seeds and rhizomes (root- like underground stems). The following simple guidelines will ensure that your efforts to control the spread of purple loosestrife are effective. Purple loosestrife is classified as noxious weed in almost all countries of the USA and Canada. Seeds are produced in a tiny, rounded seedpod/capsule, 3-6 mm in length and 2 mm broad with two valves enclosed in a calyx (a cuplike structure). Plants in northern regions are smaller and flower earlier than those in southern regions. What does purple loosestrife look like? Purple loosestrife was introduced to North America during the 19 th century. Swamp-loosestrife is an attractive native wetland plant, not to be confused with the highly invasive purple loosestrife (Lythrum salicaria). It was first introduced into North America in the early 1800s for ornamental and medicinal purposes. The ecology and management of purple loosestrife (Lythrum salicaria L.) in central New York. Native to Eurasia, purple loosestrife ... Purple loosestrife is an erect perennial herb that usually grows two to six feet tall. To date, this invasive plant is found in every Canadian province and every American state except Florida, Alaska, and Hawaii. Each stem is four- to six-sided. Stems are woody, stiff, and square-shaped, with 4-6 sides. Food Uses of Purple Loosestrife. When purple loosestrife enters an area its stiff stems can collect debris such as silt (sedimentation). Did you know? Purple loosestrife has a square, woody stem. It creates a dense purple landscape that competes with native plants and deters wildlife. Buy native or non-invasive plants from reputable retailers. Dense stands also reduce water flow in ditches and the thick growth of purple loosestrife can impede boat travel. American Bee Journal, April, 214-215. Dense purple loosestrife stands can clog irrigation canals, degrade farmland, and reduce forage value of pastures. Identification: Purple loosestrife is an erect perennial herb in the loosestrife family (Lythraceae) that develops a strong taproot, and may have up to 50 stems arising from its base. This can dry up a shallow water habitat and make it into a terrestrial area, destroying the habitat for native aquatic animals that have been living there. It was introduced to North America on several occasions: intentionally as a garden herb and accidentally in ship ballast. Description The most notable characteristic of purple loosestrife is the showy spike of rose-purple flowers it displays in mid to late summer. Purple Loosestrife (Lythrum salicaria) 1 Introduction Purple loosestrife (Lythrum salicaria L.) is an invasive, emergent, perennial plant, native to Europe and Asia. ), which only have one flowering stalk. A change in nutrient cycling and a reduction in habitat and food leads ultimately to reductions in species diversity and species richness. It is very common along the lower Saint John River and is still spreading. This can dry up a shallow water habitat and make it into a terrestrial area, destroying the habitat for native aquatic animals that have been living there. L. Seabacher WA Dept. See Grow Me Instead: Beautiful Non-Invasive Plants for Your Garden. The Problem. Do not compost them or discard them in natural areas. Seed capsules form in mid to late summer, and each capsule contains many small seeds. It is a successful colonizer and potential invader of any wet, disturbed site in North America. Roots: The strong, persistent taproot becomes woody with age and stores nutrients which provide the plant with reserves of energy for spring or stressful periods. These populations result in changes to ecosystem functions, including reduced nesting sites, shelter, and food for birds, as well as an overall decline in biodiversity. Invasive species cause recreational, economic and ecological damage—changing how residents and visitors use and enjoy Minnesota waters.Purple loosestrife impacts: 1.
