Purple Loosestrife

(Lythrum salicaria L.)

By: Linnea N.

Purple Loosestrife is originally from Eurasia and was introduced to North America in the early 1800's. There are pinkish-purplish flowers growing out of the long green stem which can reach lengths of up to 2 meters. It grows in wet meadows, marshes, rivers, reservoirs and edges of rivers and ponds. One Purple Loosestrife is able to make up to 3 million seeds in a year. There can be up to 80,000 stalks per acre. Bees will pollinate the flowers. Once it has established, purple loosestrife is very hard to eliminate. Purple loosestrife can come back from the tiniest piece of a root in the soil. Nicknames for Purple Loosestrife are beautiful killer, marsh monster and exotic invader. It has proven that it has earned these nicknames. This plant is dangerous because it can block or disrupt water flow and can crowd native wetland plants. To get rid of Purple Loosestrife four insects, the two leaf eating beetles, a root mining weevil, and a seed weevil were approved for release to help the further growth and infestation of purple loosestrife in Canada.
