It is possible that it is yellow sorrel. Follow link to see pic.

I don’t know that’s my question to you
Tulips close at night , because when sun rises in the morning temperature of the atmosphere rises and rate of transpiration increases with the increase of temperature. so tulips cells loses water potential and become lose and become open. when day passed on and temperature become low than water potential increases and become tight so tulips close at night. Flowers also close their petals to keep out 'the wrong type' of insect. Flowers that close their petals at night are called 'photonastic'.
Flowers that bloom at night are trying to attract night flying insects and animals to pollinate them. Such flowers are usually pollinated by moths and (strangely enough) by bats.
Yes, tulips typically open during the day and close at night. This behavior is known as nyctinasty, which is a natural response to changes in light and temperature. Tulips usually open in the morning and close in the evening to protect their flowers and conserve energy.
Unlike trees, which have leaves that open their stomata during the heat of desert days and close them during the cool of the night, the agaves and yuccas have leaves that close their stomata during the day and open them at night. The trees' leaves take in carbon dioxide and expel oxygen and, wastefully, their water vapor during the hot day, as they carry out the process of photosynthesis. The thrifty agaves and yuccas, by contrast, take in - and chemically store in an organic acid - carbon dioxide and expel oxygen and water vapor at night. With dawn, when the sunlight becomes available as fuel, they close their stomata to minimize evaporation, release their carbon dioxide and proceed with photosynthesis.
When it's light, the plant needs CO2 (carbon dioxide) for photosynthesis, so the stomata opens. At night (darkness) they close to conserve water.

yes...i have a hibiscus flower at home and saw it closed....
Some flowers close up at night, this could be considered sleeping.
The garden flowers or wild flowers that close at night are Morning Glories, Crocus's and Sun Daisies. Hedgehog Cactus also close at night.
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.
Because they are beautiful flowers and they open in the morning and close at night.

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.
At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.
Nyctinasty is the name for movements by plants triggered by changes in light intensity and warmth towards nightfall which includes closing flowers and leaves. You could call the closing of a flower at night a "nyctinastic movement".
As with most night flowering plants the flowers are white ,as they are pollinated by moths and other night flying insects this makes them more easilly seen.
