Invasive spiky weed spotted spreading in Wisconsin town

Invasive Species
If you tend a prairie patch, roadside, or vacant lot near Beloit, this tall spiky weed can crowd out native wildflowers and grasses within a few growing seasons.
Someone spotted a cutleaf teasel plant growing in Beloit, Wisconsin, and confirmed it well enough that iNaturalist marked the sighting as research-grade. This spiky, thistle-like plant isn't native to North America and tends to take over open areas like meadows and roadsides, so tracking exactly where it shows up helps land managers and gardeners know where to watch for it and pull it before it spreads further.
