A new crackdown on invasive plants is making more crops illegal to sell and buy in Illinois.
The state's Exotic Weeds Act was expanded as of October 1 to prohibit nine new plants, according to the University of Illinois Urbana-Champaign.
The nine crops have been added to a list of over two dozen that are illegal to "buy, sell, distribute, or plant" across the state. They include tree of heaven, garlic mustard, leafy spurge, sericea lespedeza, Japanese stiltgrass, Amur corktree, black swallowwort, and pale swallowwort. Callery pear trees will be phased out gradually and will be banned as of January 1, 2028.
Though they are now regulated, it is not illegal to possess any of these plants or have them growing in one's yard. They can all spread naturally and do not require removal if they are already growing in your space. But even though removal isn't a legal requirement, it might be a good idea if you want to keep your garden healthy and beautiful.
"Invasive plants can crowd out native species, reduce wildlife habitat and forage, change the soil chemistry, and even limit the growth and regeneration of native trees," said Chris Evans, a University of Illinois Extension forestry and research specialist, per the school's release.
Invasive species can grow rapidly and outcompete native plants for essential resources like water, sunlight, and nutrients. They can also be a real headache to get rid of, and the process can take a lot of time and money.

One trick that will lower your water bills, conserve water, and save time and money is to rewild or upgrade to a native plant lawn. Reaping the benefits could be as simple as planting a small patch of clover or buffalo grass.
Pollinators love native crops, and since they are vital to the planet's food supply, anything that helps pollinators thrive is mutually beneficial.
