They are closely related to "Potentilla" and "Fragaria".  From a basal rosette of leaves, they produce flowers on wiry stalks, in shades of white, red, yellow, and orange, in midsummer.  "Geum" species are evergreen except where winter temperatures drop below 0 °F .  The cultivars 'Lady Stratheden' and 'Mrs J. Bradshaw' have gained the Royal Horticultural Society's Award of Garden Merit.
