Geum × catlingii, or Catling's avens, is a plant in the rose family, Rosaceae.
It is known from eastern Canada, where it arises from natural hybridization between the native G. canadense Jacq.
and the introduced G. urbanum L.[1][2] It is named after Paul M. Catling, the botanist who first observed the hybrid.
Geum ×catlingii is a hybrid taxon, and as such exhibits variable morphology.
However, several characters in combination help distinguish it from other Geum species:[1] It has been noted to bloom throughout the summer, after other species have shed their petals.
