Wild parsnip & Japanese knotweed

Wild parsnip and Japanese knotweed are particularly pesky plants, causing problems for people and wildlife. In Minnesota, both plants are prohibited noxious weeds. To control these plants, we need more precise information about when they develop flowers, fruits and seeds. You can help gather that information by becoming a Pesky Plant Tracker.
