Species: G. canadense
This plant grows in the Cardin Alvar micro-environment. Alvars occur around the globe where receding glacial ice left exposed limestone pavements. The plants include many western species not generally found in the northeast.

I was surprised and pleased to turn up a couple of unassuming little native wildflowers on a walk around the local pond last summer. Flower 16 mm (5/8") across. A great example of a continuum in leaf form: upper leaves are simple, middle are lobed, & lower are compound (three leaflets).
Geum /ˈdʒiːəm/, commonly called avens, is a genus of about 50 species of rhizomatous perennial herbaceous plants in the rose family Rosaceae, native to Europe, Asia, North and South America, Africa, and New Zealand. They are closely related to Potentilla and Fragaria. From a basal rosette of leaves they produce flowers on wiry stalks, in shades of red, yellow and orange, in midsummer. Geum species are evergreen except where winter temperatures drop below 0 °F (−18 °C)....
