How Often Does Queen Of The Night Bloom? Queen of the Night blooms rarely, and there is no guarantee that it will flower every year. When it does bloom, its flowers appear only at night, and in a brief time window.

According to Desert Queen, cooler nighttime temperatures are necessary for Queen of the Night’s pollinators to come out. As a result, Queen of the Night does not need to compete for pollinators with other plants that bloom during the day. This adaptation is similar to how some plants thrive in acidic soil that others cannot tolerate (for example, azaleas, blueberries, and some other plants prefer a soil pH of around 5.0, whereas most plants prefer a pH of 6.0 to 7.0.)
