Purple loosestrife is a tall erect plant with a square woody stem which can grow from four to ten feet high, depending on conditions. Leaves are lance shaped, stalkless, and heart-shaped or rounded at the base. They produce numerous spikes of purple flowers throughout most of the summer.

What characteristics of purple loosestrife make it an invasive species?
Threat to Minnesota Waters Purple loosestrife impacts: Dense growth along shoreland areas makes it difficult to access open water. Overtakes habitat and outcompetes native aquatic plants, potentially lowering diversity. Provides unsuitable shelter, food, and nesting habitat for native animals.
What is a description of a purple loosestrife?
Description. Purple loosestrife is an erect perennial herb that usually grows two to six feet tall. A mature plant can develop into a large clump of stems up to five feet in diameter. Each stem is four- to six-sided. The root system consists of a very thick and hard taproot, and spreading lateral roots.
What is purple loosestrife and why is it a problem?
Why Is Purple Loosestrife a Problem? Purple loosestrife negatively affects both wildlife and agriculture. It displaces and replaces native flora and fauna, eliminating food, nesting and shelter for wildlife. By reducing habitat size, purple loosestrife has a negative impact of fish spawning and waterfowl habitat.
How do you identify purple loosestrife?
Purple Loosestrife may be distinguished from other species of Lythrum by its stems that end in dense, showy flower spikes. The lance-shaped leaves are up to 4 inches long, and mostly opposite or in whorls of 3 (which may appear alternately arranged). Some leaf bases are heart-shaped and may clasp the main stem.
What are some fun facts about the purple loosestrife?
Purple loosestrife blooms from July to September and attracts bees, that are responsible for the pollination of this plant. Fruit of purple loosestrife is capsule filled with numerous seed. One plant is able to produce 2.5 million seed per year. Purple loosestrife propagates via seed and shoots that grow from the root.
What species are affected by purple loosestrife?
Without the natural biodiversity of these areas, animals and insects are affected, as well. Bog turtles, black terns, and canvasback ducks are all experiencing population declines partly due to the Purple Loosestrife invasion.
What was the purpose of purple loosestrife?
Purple loosestrife was introduced to North America in the 1800s for beekeeping, as an ornamental plant, and in discarded soil used as ballast on ships.
What are purple loosestrife adaptations?
The Purple Loosestrife adapted to produce a lot more seeds than it once produced. This has helped the Purple Loosestrife’s rapid spread. The Purple Loosestrife has also been recently found to have rapid climate adaptation. This ability has helped the extremely rapid spread and invasive spread across the country.
What is the purple loosestrife native habitat?
Preferred Habitat: Purple loosestrife can be found in variety of wetland habitats including freshwater tidal and non-tidal marshes, river banks, ditches, wet meadows, and edges of ponds and reservoirs.
What negative effects does the purple loosestrife have on its new ecosystem?
ECOLOGICAL DAMAGE Purple loosestrife degrades natural habitats such as wetlands and riparian areas reducing biological diversity by outcompeting native vegetation. White et al. (1993) reported purple loosestrife as an alien species that presents a serious threat to native plant communities of natural habitats.
Do bees like purple loosestrife?
It blooms purple pink spires of flowers from spring to frost and attracts bees, bumblebees, butterflies and hummingbirds all season. It is perennial, requires no maintenance and likes moist soil. Any information you could share would be greatly appreciated.
Are purple loosestrife an invasive species?
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. Since it was brought to North America, purple loosestrife has become a serious invader of wetlands, roadsides and disturbed areas.
What kills purple loosestrife?
Glyphosate herbicides are very effective for killing purple loosestrife. Glyphosate is available under the trade names Roundup, Rodeo, Pondmaster and Eagre. Only aquatic formulations of Glyphosate may be used to control purple loosestrife at aquatic sites (such as Rodeo, Pondmaster and Eagre).
How do people use purple loosestrife?
People use purple loosestrife as a tea for diarrhea, intestinal problems, and bacterial infections. They also use it for swelling and as a drying agent. Women use it for menstrual problems.
What beetle eats purple loosestrife?
Galerucella pusilla and G. calmariensis are leaf-eating beetles which seriously affect growth and seed production by feeding on the leaves and new shoot growth of purple loosestrife plants. Hylobius transversovittatus is a root-boring weevil that deposits its eggs in the lower stem of purple loosestrife plants.
