iNaturalist: luke94664
Invasive Species
Herb Robert is quietly spreading through Pacific Northwest gardens and forest edges, and once established it can crowd out native wildflowers you might be trying to grow or preserve.
Someone in Oregon spotted and photographed a plant called Herb Robert, a small weedy geranium originally from Europe with delicate pink flowers and a distinctive musty smell. The observation was verified as accurate by the iNaturalist community, making it an official data point in tracking where this plant is growing. Herb Robert has been spreading across the Pacific Northwest and can take over shady garden spots and forest understories.
