Phenology
If you've noticed bright yellow daisy-like flowers popping up along trails and roadsides lately, you're not imagining it: this is peak bloom season for one of North America's most recognizable native wildflowers.
Black-eyed Susan, that cheerful yellow flower with the dark brown center, is showing up in huge numbers on iNaturalist this week, with 882 people logging confirmed sightings. This kind of spike usually means the plant has hit its peak flowering window for the season. It's a good reminder to look for one on your next walk, since they're easy to spot and thrive in gardens, meadows, and roadside patches alike.
