Moon flowers open in the evening so they can be pollinated by night-flying moths. Like most moth-pollinated flowers, the moon flower is white, which attracts moths. The moon flower is a close relative of the morning glory, which opens in the morning so it can be pollinated by bees and other insects that are active during the day. Although not shown in this movie, the moon flower petals die in the morning after they open. This flower was filmed on a cool fall evening. The flower started to open around 6:00 pm and was filmed until just after 8:00 pm. On a warm summer night, moon flowers can open in a matter of several minutes.
