Is there a plausible scientific explanation for why a specific flower might bloom precisely at the time of daily prayer calls, or is this purely coincidental/anecdotal?

  A family member insists their garden's morning glory blooms exactly at the Fajr (dawn) prayer call, seeing it as a spiritual sign. As a philosopher of science with a biology background, I'm curious if there's a rational explanation. Could it be a circadian rhythm tuned to a specific light/temperature threshold that coincides with that time? Could subtle vibrations from the call affect it? Or is this a classic case of apophenia (seeing meaningful patterns in random data) combined with confirmation bias? How would one design a simple controlled experiment to test this?

A scientific explanation is highly plausible and likely involves circadian rhythms entrained by light, temperature, or humidity changes at dawn. Many flowers have evolved to open at specific times to optimize pollination. The precise coincidence with the prayer call is likely fortuitous timing, not causation. The sound vibrations are an improbable trigger, as plants largely lack mechanoreceptors for airborne sound at that intensity. The perception of a meaningful link is a textbook case of apophenia and confirmation bias—the flower may sometimes bloom a bit before or after, but those instances are forgotten, while the coincidences are remembered. A simple experiment: shield the plant from the call's sound (but not light/temperature) using a soundproof box with a clear window, and observe if blooming time shifts. My scientific bet is it won't; the rhythm is driven by environmental cues, not acoustic ones.
