Hibiscus flowers close up at night as a way to conserve energy and protect themselves from cooler temperatures and potential damage from nighttime pests.
Some flowers close up at night, this could be considered sleeping.
Morning Glory, Crocus, Bloodroot, Hedgehog Cactus, Sun Daisies just to name a few. When flowers close temporarily for the night they are effectively in standby mode, protecting their delicate reproductive parts and pollen while they are not in use. The pollen is isolated from the dew that forms during the night, keeping it dry so that it can be dusted onto a passing insect the following day. Closing the flowers also helps to protect against night-time cold and bad weather.
Hibiscus is non toxic, but it wilts very quickly after being picked if not in a water source. If it is going to be left any more than about 20 minutes, it will shrivel up. Hibiscus flowers are much more delicate than they appear. The petals are tissue thin.
Answer 1 Not all of them close -- "night-blooming jasmine" for example. They close at night because of the light and the temperature changes Answer 2 Saying that flowers close at night because of light and temperature changes is in effect saying they close at night because it is night. It is not an explanation because if it didn't benefit them flowers would have evolved ways to stay open. What is needed is an explanation of the advantages it gives the flower to use up extra energy closing at night then opening in the day. The probable reason is that the dew at night and early morning prevents the pollen from being spread, the low temperatures at night harm the pollen, the moths and other night life do more harm than good to the pollen and so on.
