Some plants bloom at night, they rely on insect pollination that is active at night, including common moths, and some will attract bats to pollinate, and the flowers of these night-flowering plants are fragrant, so that insects can know their existence from a distance.
Above them are Ephemeral, Big Flower Snake Whip Pillar and Purple Jasmine
Species 1: Purple Jasmine (Mirabilis jalapa)
Purple jasmine is also called landmine flower, supper flower, it is a very rich perennial herb flower, it is particularly easy to grow branches, the plant is relatively tall, purple jasmine flowers like a trumpet, the flower color is usually purple, pink, yellow or red (there are many mixed color varieties).

Purple jasmine plants do not grow particularly tall, generally 50 to 90 cm tall, very suitable for growing ornamental pots, but it should be noted that the planted pots are larger and deeper, because its root system will grow more vigorously. Its root system bottom even grows small roots, the planted soil should be as loose and breathable as possible, with good drainage, but also have the appropriate fertility to ensure the healthy growth of the plant.
In addition to maintaining a warm and cool environment all year round, the maintenance of purple jasmine should also pay attention to ensuring that there is more light, at least to ensure that there are more than 4 to 6 hours of sunlight per day, it can also grow in the semi-shade, but the amount of flowers will be reduced. Avoid exposure to the sun when the temperature is too high, in the summer the temperature is above 38 degrees, it is best to keep it in the shade or on a balcony in the shade, too strong light will cause the leaves to fall off.
Purple jasmine's hardiness is not too good, and in winter, when the temperature is below 4 degrees, the part on the ground is easy to freeze off, but as long as its rhizome is still alive, it can also re-take root and sprout in the next year.
Species 2: Oenothera

In the later stage, the environment of the night incense tree must be kept warm, with high air humidity, but also pay attention to more light, and it is best to have more than 4 hours of direct light every day.
It is necessary to pay attention to ensuring that the soil is slightly acidic, avoiding the soil alkaline, and maintaining the maintenance temperature in winter at more than 4 degrees, which will be more beneficial to the growth of nightweed trees.
The maintenance difficulty of the night incense tree is relatively low, the most critical thing is actually the environment, if it is in the southern area, such as Liangguang, Yunnan and Fujian, it can often be seen in some parks or botanical gardens.
Type 4: Large Flower Snake Whip (Selenicereus grandiflorus)
The flowers of the large-flowered snake whip pillar are particularly similar to the ephemeral flowers, which are perennial plants belonging to the genus Snake Whip pillar of the cactus family, it is also considered a succulent plant, the plant will grow particularly tall, it can be wrapped around the tree to climb, and its stem grows particularly slender.
Under the right conditions, the large flower snake whip pillar will bloom charming white flowers in the summer and autumn of each year, its flowers are opened at night, the floral fragrance is attractive, and the red berries (edible) will be bred after flowering.
The big flower snake whip pillar is native to the Americas, it likes the tropical rainforest type environment, it has always been a relatively niche ornamental plant, suitable for raising in a semi-shady environment, every day need to have 3 to 8 hours of soft light, the maintenance of the environment to have a higher air humidity.
In addition, we must pay attention to ensure that the environment is ventilated, maintain the warmth of the environment, the minimum temperature is best maintained at more than 7 degrees, but also pay attention to the large flower snake whip column to provide some humus-rich, fertile and loose potted soil, generally recommended to use common humus soil, peat soil and perlite, the mixing ratio is about 5:3:2, and then appropriately add some slow-release fertilizer or organic manure as the bottom fertilizer, can make it grow better.
Species 5: Epiphyllum oxypetalum
The conservation method of the ephemeral flower is slightly similar to the large flower snake whip column, the form of the ephemeral flower will be more beautiful, its leaves are relatively flat, it is some lanceolate, and there are wavy lines on the edges of the leaves, even if it does not flower, the leaves have good ornamentality.
Ephemeral flowers like a warm and cool environment all year round, more afraid of cold and excessive exposure, it is best to have more than 4 to 6 hours of soft light every day, the light is too strong, the leaves will be sunburned. In addition, it is necessary to ensure that the environment is ventilated and the air humidity is high, and the leaves do not often retain dust.
If you want to make the potted ephemeral flowers bloom normally, it is best to have a long period of sunlight during the day, maintain a cool environment at night, pay attention to maintaining a certain air humidity, thin fertilizer application during the growth period, and stop fertilizing in summer high temperature and low temperature in winter, which is conducive to its flowering.
The temperature of planting ephemeral flowers is best maintained between 15 and 25 degrees, and at night, the temperature is lower (the minimum temperature should be maintained above 5 degrees), which is conducive to promoting the formation of flower buds.
Species 6: Safflower water lily and Egyptian white water lily
Most water lilies bloom during the day and close at night.
