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)....
