3.5-inch pocket-sized card
Describes how to identify purple loosestrife. It is invading wetlands, shorelines and roadside ditches. Thick stands crowd out native plants and reduce food, shelter and nesting sites for wildlife, birds, turtles and frogs.
We no longer have identification cards for the purple loosestrife (Lythrum salicaria).
