iNaturalist: spochron
Summary
iNaturalistWhy it matters This matters because common groundsel is a prolific weed that can quickly take over garden beds and is toxic to livestock and pets, so knowing where it's spreading helps gardeners and land managers stay ahead of it.
Common groundsel is a small, fast-growing weed with tiny yellow flowers that shows up in gardens, roadsides, and disturbed soil. Someone spotted and confirmed it in Calverton, New York, adding a verified data point to the map of where this plant lives. It spreads quickly and produces seeds year-round, making it one of those plants that can quietly take over if you're not watching.
