Thought of as an invasive nuisance to many people, especially duck hunters, Purple loosestrife is an adaptable and long-lived species. It is this adaptability that caused it to spread at an alarming rate when it was introduced in North America. When found in an area with water sources, it can disrupt water flow, and therefore cause a sharp decline in the biodiversity of the area. A single plant can produce up to 3 million seeds, making it a very difficult plant to eradicate.
It should be noted that not all people find Lythrum a problem. Beekeepers rely on this plant as source of late season pollen and nectar for their hives.
Purple loosestrife is a tall, upright herbaceous perennial plant. Forming colonies, this plant can grow 1-1.5 metres tall. A single root mass can have numerous erect stems growing from it. The flowers, reddish purple in colour, are produced in whorled spikes from mid-summer to mid-autumn. There are three different flower types which have stamens and styles of different lengths. Each flower can only be pollinated by one of the other types. This ensures cross-pollination between different plants.
Although finding information on the medicinal uses of this herb can be difficult, Lythrum has a long history of use in European folk medicine. It was most notably used during the cholera outbreaks in that region during the 19th century.
