Invasive Species
Wild radish can take over disturbed roadsides, farm edges, and open spaces in your neighborhood, crowding out native wildflowers before you even notice it spreading.
Someone walking around Santa Clara County found and photographed a wild radish plant, and enough people confirmed the ID that it earned 'research-grade' status on iNaturalist. Wild radish is originally from Europe and spreads aggressively across disturbed ground, roadsides, and fields. Sightings like this help scientists and land managers track where it's showing up and how fast it's spreading.
