Window flowers

One possibility that occurs to me, and that hasn't been mentioned
yet, about window flowers, is that some flowers (especially alpines)
have adaptations that appear to raise the temperature inside the
flower. This both attracts insect pollinators and increases the
likelihood of fertilization. Would the extra light entering through
the windows do this? I seem to recall that some Ranunculaceae that
flower very early have window petals.
