Dense purple loosestrife stands can clog irrigation canals, degrade farmland, and reduce forage value of pastures. It was brought to North America in the early 1800s through a number of pathways including ship ballast, imported livestock, bedding and feed, sheep fleece, as seed for gardens and for use in Purple loosestrife — chances are you’ve seen it growing along the roads, and you may even have thought its purple spires were a thing of beauty. Plants holds little food value, cover and nesting material for animals and leads to a reduction in habitat diversity. Purple loosestrife (Lythrum salicaria) is a restricted species in Michigan.It can grow 4-10 feet tall with opposite leaves. To test this hypothesis, we constructed mixed and monospecific plots of the two species. A change in nutrient cycling and a reduction in habitat and food leads ultimately to reductions in species diversity and species richness. Horticulturists subsequently propagated it as an ornamental bedding plant. State designated noxious weed; pink to purple flowers bloom July-September; leaves are heartshaped; height to 8 ft. Habitat. Background. Plants are usually covered by a downy pubescence. Hayes B, 1979. Established infesta-tions are extremely difficult to get rid of, so prevention and control of isolated new plants is very important. Purple loosestrife plants in gardens are capable of causing the spread of purple loosestrife into natural areas through its seeds. Native plants are vital to wetland wildlife for food and shelter. E-mail: info@bcinvasives.ca This results in the decrease of the recreational use of wetlands for hunting, trapping, fishing, bird watching, and nature studies. Appearance Lythrum salicaria is a tall, multistemmed (30-50 per plant), perennial forb that can grow up to 10 ft. (3 m) in height. It outcompete with natural plants and you should therefore take care off, that plants from your garden do not escape. Where purple loosestrife dominates, the invasive plant can decrease food resources available for bog turtles. The plant mass grows on average to be 60-120 cm tall and averages 1-15 flowering stems. It is important to dispose of the plants away from the water. Leaves: Leaves are simple, narrow and lance-shaped or triangular, with smooth edges and fine hairs. 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. The plant itself benefits few foraging animals, although it can be a source of nectar for bees. Purple loosestrife (Lythrum salicaria), a beautiful but aggressive invader, arrived in eastern North America in the early 1800’s. (3.8-10.2 cm) long and round or heart-shaped at the base.
