What is it? This plant is 3' - 7' tall and
looks like a spike with small
purple flowers. It likes to grow in wetlands, along
lake shores, waterways, roadsides, and in other moist areas.
What's the problem? Originally from Europe
and Asia, this plant can
grow so thick that it crowds out our native plants.
Dense stands of purple loosestrife make it unsuitable for a
wide variety of native wetland animals and wildlife.
How is it spread? One plant can produce
over 2 MILLION seeds! It is able to resprout from
broken stems that fall to the ground or into the water.
How do I recognize it?
3 - 7' tall
Spike covered with many purple flowers
Leaves usually paired opposite
Stem has ridges
Porters Lake already has it. What is being
done? Once Purple Loosestrife has invaded an area,
it cannot be completely eliminated.
The goal is to control the amount of the plant so that it
does not interfere with native plants and animals.
For several years Dave "The Beetle Man" Hansen has been
raising and releasing the Galerucella beetle into infested
areas. Since implementing the program there has been a
sharp reduction in the amount of Purple Loosestrife
surrounding Porters Lake.
