The most amazing feature of the bashful Mimosa is that from a light touch, she folds her leaves. However, the plant has two types of movement. Like a number of other species of higher plants, bashful mimosa can gradually change the orientation of the leaf over time (nyctinasty), and the leaves can also close under the influence of external stimuli (seismonastia), such as touching, warming, wind or shaking.
In 1729, the French astronomer de Meirins reported on the daily leaf movements of the bashful mimosa (Mimosa pudica). These movements were repeated with a certain periodicity, even if the plants were placed in darkness, where there were no external stimuli such as light, which suggested an endogenous origin (geological processes associated with the energy arising in the interior of the Earth) biological rhythms to which the movements of leaves were confined plants. De Meiren suggested that these rhythms may have something to do with the alternation of sleep and wakefulness in humans.
Alphonse Decandol, a Swiss botanist and biogeographer, determined in 1832 that the period with which mimosa plants make these leaf movements is shorter than the length of the day and is approximately 22-23 hours.

Description of bashful mimosa
Mimosa bashful is an evergreen ornamental shrub native to the subtropics of South America. The bashful mimosa got its distribution due to its bizarre property to react to any touch, even a light wind. She immediately begins to fold her leaves. It seems that she is moving. In order to preserve decorative properties, it is often grown as an annual crop. You should not touch the leaves often.
Bashful mimosa (Mimosa pudica) is a perennial herb 30-60 cm in height, less often - up to 1.5 m, a type of plant from the genus Mimosa of the legume family. The most famous species. Its bipinnate leaves are especially sensitive, folding and falling in the dark from the lightest touch and other irritating reasons. Fruit - a pod, 2-8 pieces in pods. The flowers are collected in small light pink or lilac axillary globular heads at the ends of the branches. Pollinated by wind and insects.
Mimosa bashful at home
Despite the fact that mimosa, at first glance, seems so gentle, caring for it, in fact, is not difficult. She loves warmth, the air temperature, from early spring to late autumn, should be between 20-24 ° C. In winter, lower the temperature to 16-18 ° C. Loves bright light, even direct sunlight.
In the spring and summer, watering should be abundant and regular. In winter, it is enough to keep the soil in a slightly damp state. Its only feature is that it absolutely does not tolerate tobacco smoke, immediately throws off the leaves. Propagated by seeds.
Seeds of bashful mimosa are sown in February-March in moist, loose soil without fertilization, in a drained mixture of sod, leaf, peat soil and sand (1: 1: 1: 1). The box is covered with foil and placed in a warm place.
For uniform correct growth, mimosa needs bright light, unlike many plants, it responds well to direct sunlight.
When seedlings appear, they are transplanted into separate pots, which are then placed on a well-lit windowsill. Recently acquired plants or plants, after a long cloudy period, are gradually accustomed to direct sun in order to avoid sunburn.
Mimosa blooms in favorable conditions for about 4 months. In winter, mimosa most often dies. To repeat the joy of meeting an amazing plant next year, you can collect seeds, as well as trim the tops of the shoots.
I must say that rooting cuttings is a big problem. Seedlings, as a rule, die after a year of life, in case of failure in the spring, seeds should be sown again.
A transplant is usually not required; you should not disturb the plant unless absolutely necessary. Moreover, there is no need for a transplant with an annual culture. If a transplant is necessary, it is best to transfer the plant to a larger pot without disturbing the earthen coma. For transplantation, a substrate of equal parts of sod land, leaf humus, peat and sand is suitable. Provide good drainage at the bottom of the pot.
The bashful mimosa is affected by the green apple aphid, which is disposed of with the help of appropriate preparations. The mealybug is removed with a rag or cotton swab dipped in alcohol, and subsequent treatment with anticoccidal drugs.
Why do the bashful mimosa leaves close?
When a force is applied to the mimosa leaves, for example, a touch, the cells of the plant's leaves lose their turgor pressure - the internal pressure of the cell. This is due to the release of chemicals, including potassium, which removes water from the cells. As soon as the leaf is deprived of water, it wilts. This feature is found in other plants of the genus Mimosa.
It is not known exactly why the bashful mimosa developed this property. Scientists suggest that it appeared to scare away herbivores or insect pests.
I am waiting for your feedback on this small, modest, but interesting flower.
