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. canadenseJacq. and the introducedG. urbanumL.[1][2] It is named after Paul M. Catling, the botanist who first observed the hybrid.

Descriptionedit
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]
Hybrid vigor - hybrids tend to be larger than parents
Petals are creamy-yellow - intermediate between dark yellow (G. urbanum) and white (G. canadense).
It has been noted to bloom throughout the summer, after other species have shed their petals.[3]
