Purple Loosestrife (Lythrum Salicaria)

About Purple Loosestrife

Purple Loosestrife is a beautiful but aggressive hardy perennial that rapidly degrades and chokes wetlands and erodes wildlife habitats. It can grow up to 3 m (9ft) at maturity, has an erect 4 sided stem with heart shaped or rounded leaves at the bottom and a showy spike of delicate purple flowers (not to be mistaken for fireweed that has a rounded stem and prefers drier conditions). Once flower petals start to drop from the bottom of the spike, the plant begins to produce seeds and spreads. Each mature plant can produce over 2 million seeds per year. The best time to control is in late June, July and early August. The plant is now encroaching on farmer’s crops and pasture land and impacting native plants, amphibians, birds and other wetland species.
