What is the growth environment of four-leaf clover? Why do the leaves of four-leaf clover close up at night?

Four-leaf clover, also known as lucky grass, is a perennial herb with only three small leaves. The leaves are heart-shaped, and the darker part of the heart is also heart-shaped. The most interesting and special thing is that among 100,000 alfalfa plants, you may only find one that is a "four-leaf clover", because the chance is about one in 100,000. The first leaf represents true love, the second leaf represents health, the third leaf represents reputation, and the fourth leaf represents happiness. [Introduction]: A long time ago, there was a legend that Eve took the [four-leaf clover] out of the Garden of Eden. It is rare and it also represents luck. If you can find a four-leaf clover among three-leaf clover, then you will have unexpected luck.

What is the growing environment of four-leaf clover like?

Four-leaf clover is not very demanding on soil and can adapt to various soil types. It grows well on slightly acidic soil and prefers warm, sunny and well-drained environmental conditions. It grows slowly under drought conditions and some of it dies in high temperature seasons. It is resistant to pruning and trampling, and has strong regeneration ability. It can grow new leaflets within 10 days after pruning. It can recover 3 to 5 days after high-intensity trampling or rolling. It has strong cold resistance. When the temperature drops to 0℃, some old leaves turn yellow, and the leaflets on the taproot are close to the ground and stop growing, but they still remain green. It is easy to grow too long under strong shade, resulting in poor growth. It has strong resistance to harmful gas pollution and pests and diseases.

Why do four-leaf clover leaves close up at night?

Plants also sleep. This form of movement, which changes with the light and dark cycle of day and night, is a sensory movement caused by the stimulation of the arrival of night. It is also called night-sensing movement or sleep movement. Many plants have this movement. For example, the leaves of peanuts, soybeans, albizzia and mimosa stretch out towards the morning sun during the day and close in pairs at night. The night-sensing movement of tamarind is manifested in that the leaves face down at night and face up during the day. During the day, under the sun, the auxin produced in the leaves moves toward the petiole and is more concentrated in the part of the leaf connected to the sieve tube on the lower side of the petiole. Due to the higher auxin concentration in this part, it grows faster, resulting in the leaves facing upward. At night, the auxin content on the upper side of the petiole is higher than that on the lower side, which accelerates the growth of the upper side, resulting in the leaves facing downward to prevent water loss.
