	Purple Loosestrife
		Purple loosestrife has flowers with 5 to 7 purple petals; the leaves are opposite or in whorls of 3, all lacking teeth; and it has a stiff 4-sided stem that may appear woody at the base of large plants.
		Purple loosestrife is an herbaceous perennial that may be from 3 to 10 feet tall, with an average height of 5 feet, and it flowers from early July to early September.

		The plant is a member of the loosestrife family (Lythraceae) and may be confused with other members of that family, particularly with the native winged loosestrife (Lythrum alatum), which is rare in Virginia.

	Curbing Wetland Destruction by Purple Loosestrife (Site not responding. Last check: 2007-10-08)
		Although purple loosestrife does add a bright splash of color to the landscape in midsummer, it eliminates native plants, food and shelter for wildlife and spawning grounds for fish.
		Purple loosestrife has several traits that allow it to be successful: Its tall stalks, two to seven feet, tower over most other wetland plants, shading them out, and it can also adjust to a wide range of environmental conditions, requiring only moist soil for seed germination and open, sunny areas.

	Purple Loosestrife and the "Bounding" of Nature in North American Wetlans
		The problem with the science of Purple Loosestrife can therefore be located not in mistakes made in the field, but instead in the refusal of the scientist to recognize and make explicit the social and cultural boundaries and categories that encapsulate the story of Purple Loosestrife in North America.
