Native Plants
Black-eyed Susans blooming in your yard or along roadsides right now are feeding native bees and metallic sweat bees that have few other nectar sources bridging the gap between spring and late-summer wildflowers.
Black-eyed Susan, that cheerful yellow wildflower with a dark brown center you see along roadsides and in meadows, is hitting its peak bloom across much of North America this week. Over a thousand people reported spotting it in just seven days, making it one of the most-watched plants around right now. It's a great time to look for it on a walk — and if you grow it, your garden is probably buzzing with bees.
Key Findings
1,028 research-grade observations were recorded in a single week, signaling peak bloom across North America.
The surge in sightings places black-eyed Susan among the top trending plant species on iNaturalist for the current week.
Observation volume at this scale reflects coordinated phenological timing — the species is flowering simultaneously across a wide geographic range.
