Phenology
Common blue violet is likely blooming right now in your backyard, local park, or lawn edge — and thousands of people noticing it together helps scientists track exactly when and where spring is arriving each year.
Common blue violet is a small, heart-leaved wildflower with purple blooms that pops up in lawns, woods, and roadsides every spring. This week, nearly 1,500 people across the country photographed and identified it on the iNaturalist app, making it one of the most-spotted plants of the week. All those sightings together paint a real-time picture of spring unfolding across the landscape.
Key Findings
1,483 research-grade observations of common blue violet were recorded on iNaturalist in a single week, signaling peak spring bloom activity.
The volume of sightings places common blue violet among the top trending plant species on iNaturalist this week, reflecting broad geographic spread of observations.
Research-grade status means each observation was verified by multiple community members, making this data usable for scientific studies on phenology and species distribution.
