purple crownvetch (Securigera varia) observed in W North Ave, Lombard, IL, US
iNaturalist: peacheebelle
Invasive Species
Purple crownvetch spreading along roadsides and into natural areas can outcompete native wildflowers and grasses you'd want to establish in a restoration planting or pollinator garden — knowing where it's spreading helps you stay a step ahead.
Someone spotted and documented purple crownvetch growing along a street in Lombard, Illinois. This plant is a sprawling vine originally from Europe that was once popular for erosion control but has since escaped into wild areas across much of North America. It forms dense mats that crowd out native plants, so tracking where it shows up helps naturalists and land managers respond early.
