The flowering of plants in response to changes in day length and temperature is controlled by three intricate signaling pathways. In this Perspective, Devlin and Kay examine new research ( Samach et al.) that shows how signals from the three pathways converge on the promoters of several key genes to bring about flowering in the model plant Arabidopsis.
