Invasive Species
Sulphur cinquefoil spreading into roadsides and meadows near you is an early warning sign for a pasture or restoration planting losing ground to a tough, drought-tolerant invader that's hard to remove once established.
Someone photographed and submitted a sulphur cinquefoil plant growing in Solon, New York, and enough community experts agreed on the ID to call it 'research grade.' This bright yellow-flowered plant originally comes from Europe and has spread across much of North America, especially in disturbed areas like roadsides and fields. It's not considered harmful in small numbers, but it can outcompete native wildflowers in open, dry habitats if it gets a foothold.
Key Findings
A research-grade observation of sulphur cinquefoil (Potentilla recta) was recorded in Solon, Cortland County, NY — confirming its presence in this locality.
The species is a non-native European perennial now naturalized across most of the continental United States and Canada.
Sulphur cinquefoil is listed as an invasive or noxious weed in several U.S. states due to its ability to colonize disturbed open habitats and resist grazing.

A sulphur cinquefoil plant was spotted and confirmed by the iNaturalist community in Solon, NY — a non-native European wildflower that has naturalized widely across North America and can crowd out native species in meadows and pastures.
