Black-eyed Susans are at peak bloom and feeding pollinators now
iNaturalist Community
Native Plants
Black-eyed Susans blooming in your yard or along a roadside right now are feeding the specialist bees and native butterflies that depend on late-summer nectar when most other wildflowers have already faded.
Black-eyed Susan is a cheerful yellow wildflower with a dark brown center that blooms across most of North America every summer. This week, over a thousand people submitted confirmed sightings to iNaturalist, signaling that the species is at or near peak bloom. It's a native plant that supports a wide range of pollinators and thrives in gardens with little fuss.
Key Findings
1,094 research-grade observations recorded in a single week on iNaturalist, placing it among the top trending plant species.
Surge in sightings consistent with peak mid-summer bloom period across the species' native North American range.
Research-grade status means each observation was confirmed by at least two independent identifiers, reflecting high community engagement.
