iNaturalist Community
Phenology
Those cheerful yellow flowers appearing in bare patches along roadsides and disturbed ground right now are one of the first nectar sources for early bees emerging from winter dormancy, so spotting them in your neighborhood means pollinators are actively feeding.
Colt's-foot is a tough little plant that blooms in late winter and early spring, often poking through gravel, clay, or disturbed soil before almost anything else has woken up. This week, plant watchers across the world submitted over 500 confirmed sightings to a nature-tracking app, capturing its seasonal bloom in real time. It's considered invasive in some parts of North America because it spreads aggressively, but it's also historically used in herbal medicine for coughs and lung complaints.
Key Findings
535 research-grade observations were submitted to iNaturalist in a single week, placing colt's-foot among the most-observed plant species globally for that period.
Colt's-foot (Tussilago farfara) flowers emerge before its leaves appear — an unusual trait that makes it one of the earliest identifiable spring bloomers in temperate regions.
The species thrives in disturbed, compacted, or poor soils where other plants struggle, making roadsides, construction sites, and stream banks its prime habitat.
