Potentilla norvegica (Norwegian Cinquefoil)

I found this Cinquefoil along the top of Twin Sisters. Here's an interesting excerpt from Flora of North America: "An even greater challenge is determining native versus introduced ranges, especially given the likelihood that both native and Eurasian populations are widespread in North America. Achenes are produced prolifically and easily dispersed, to the extent that Potentilla norvegica is a contaminant in clover and hay fields and considered a weed at least in Canada (P. A. Werner and J. D. Soule 1976)." For now, it sits here, in the Non-native section. Go to Wikipedia and iNaturalist for more ionformation.
