Species of flowering plant
From Wikipedia, the free encyclopedia
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.

Description
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).
- Intermediate stem bract size
- Highly sterile ovaries
It has been noted to bloom throughout the summer, after other species have shed their petals.[3]
