Abstract:
:Colour change in flowers (with age and/or after pollination) is taxonomically widespread, has evolved repeatedly, and has a range of putative selective benefits linked to modifying pollinator behaviour; however, this phenomenon seems paradoxically uncommon. We explore this paradox by reviewing the empirical evidence and argue that the evolution and maintenance of floral colour change as a signal to modify pollinator behaviour require special ecological circumstances that will often not be met across a plant population for a sustained number of generations, which potentially explains the scarcity of this phenomenon. We discuss alternative explanations for floral colour change and potentially fruitful lines of future research.
