Humans may have aced floriography, the age-old art of communication through flowers, but the colorful petals still hide imperceptible layers beneath.

Researchers from the University of Bristol have found that flowers use secret “signals of heat” to woo pollinating bees, something that remained unknown to humans until now.

The heat patterns on petals, which can be 4 to 5 degrees warmer than rest of flower, serve as cue for foraging bees while also offering cozy beds to pollinators as they maintain a body temperature to meet their metabolic requirements, notes Tree Hugger
