Among the flowers that appear in abundance on the eve of the spring holiday on March 8, there are huge armfuls of plant twigs with beautiful golden inflorescences and a delicate pleasant scent. It is commonly (and mistakenly) called "mimosa". But this is not mimosa at all - these are flowering brushes of silver acacia (Acacia dealbata), a low evergreen tree.
The real mimosa is bashful mimosa (Mimosa pudica)... Its homeland is the distant country of Brazil. This is an unusually interesting and beautiful plant from the legume family (mimosa subfamily). In my opinion, it is very suitable for keeping at home.
In the tropics of Latin American countries, bashful mimosa is a common hard-to-eradicate weed, in our climate it is cultivated as an annual plant in a greenhouse (in the open field it dies when the temperature drops to -5 ...- 6 ° C).
It is an evergreen shrub (from 0.6 to 1 m in height) with pubescent, straight thin shoots and small feathery oval leaves of a delicate green color. In the summer, he pleases us with flowering. The flowers are small, twisted into fluffy axillary spherical inflorescences with numerous purple stamens exposed on long filaments, located at the ends of the shoots. The fruits are articulated beans.
Shy mimosa is a relatively easy plant to grow and care for at home. This is a light and moisture-loving plant, for better development it requires a temperature of 22 ° C and an air humidity of 80%. When keeping the plants, the temperature is moderate, and in winter - not less than 15 ° C. She prefers bright light, responds favorably to some direct sunlight. In summer, the plant is watered abundantly (but do not allow excess moisture in a clod of earth), regularly sprayed; in winter - moderately. Transplant is very rare. The best soil composition is a mixture of turf, leaf and peat soil and sand (1: 1: 2: 1).
Shy mimosa is famous not for its appearance, but for its interesting property to fold its leaves when you touch them, for example, with a light snap of your finger. This is due to the presence of sensitive hairs at the base of its leaves that respond to touch, and, due to a change in turgor, this leads to folding of the leaves. Again, they open only after 30-60 minutes. At night, they always fold on their own.
Bashful mimosa reproduces well by stem cuttings (in spring or summer), as well as seeds (in early spring), which are scalded with hot water before sowing. Propagated by seeds that ripen annually. It is best planted as an annual plant, growing a new plant each year. The seeds are sown in March, the seedlings are dived into pots with a diameter of 7 cm. After braiding with the roots of an earthen coma, the mimosa is transferred into larger containers with good drainage at the bottom. Bowls of water are placed near the plants to humidify the air.
Shy mimosa is a plant designed exclusively for warm rooms. Its fresh leaves are used as a medicinal raw material, since they contain 1-1.5% of the alkaloids of mimosine and mimozide.

Reproduction of mimosa shy
Regardless of the fact that mimosa is considered a perennial plant, growers often breed it as an annual, as this delicate flower often dies in winter or loses its appearance, stretching out due to lack of sunlight.
Can be propagated by cuttings or sowing seeds. However, it is preferable to use seeds, because in half the cases, the cuttings die. The seeds can be obtained by artificially pollinating flowers. To do this, transfer pollen from flower to flower with a brush or simply touch one flower to another. The pods are considered ripe when they are completely dry. Seed material for the winter is stored in a paper or cloth bag in the refrigerator.
If you are not confident in your abilities, you can always purchase seeds from flower shops.
How to plant shy flower seeds
- For sowing seeds, choose small pots with a diameter of about 9 cm.
- Fill them with a mixture of rotted leaves, humus, fertile soil, which are taken in equal parts, add about half of the sand. You can buy a ready-made soil mixture with a high content of peat substrate for indoor flowers.
- The soil is spilled with a light pink solution of potassium permanganate or heated in the oven for about an hour at a temperature of 50 degrees for disinfection.
- The bottom of the pot is covered with expanded clay or fine gravel. This will prevent the root system from rotting. Then a layer of fertile soil is poured.
- The seeds do not need to be lowered into the ground or sprinkled. They can simply be pressed into the soil to a depth of 1–2 cm.
This is how ripe seeds-beans of bashful mimosa look like
The first shoots appear together
When the first pair of true leaves appears on the sprout, it must be transplanted to a permanent place. Drainage (small pebbles or expanded clay) is poured into the bottom of the selected flowerpot and filled with the same soil composition that was used when growing seedlings.
The young plant is taught to light gradually, making sure that the leaves do not get sunburn.
This is how leaves look like in a healthy, young plant.
Reproduction of mimosa
Mimosa is propagated by seed in February-April. In order for them to germinate better, soak them for 2 days and rub with sandpaper. For planting seeds, use a sand-peat mixture or soil for seedlings. They are laid out on the surface of the substrate at a distance of 5-6 cm from each other and sprinkled with soil 1 cm thick.
Crops are covered with transparent film or glass and exposed to the east, west window or under a fluorescent lamp. The seedlings that appear are fed ten days after they appear, and are planted in separate pots, several pieces at a time, when a couple of real leaves appear. The tops of young plants should not be pinched.
Propagation by cuttings is a rather complicated process. A flower grower who decides to propagate the culture by cuttings should know that not all of them will germinate.
Only the tip of the main shoot is suitable for harvesting cuttings. In order for the stalk to take root, you need to make a lot of effort and give the seedling daily attention, care, and care.
It takes 2-3 months for a room acacia cuttings to take root. Throughout this time, the seedling must be watered regularly. In addition to watering, you need to take care of sufficient lighting. The peculiarity of indoor acacia is that it grows very slowly, with a lack of sunlight, the development of the feathery beauty stops altogether - the bush will not bloom.
At home, the plant is more convenient to grow from ready-made seeds, which are sold in flower shops. The technology is simple.
It is better to plant ready-made seeds in late February - early March in moist soil. The recommended deadlines are early April.
The composition of the soil for bashful mimosa should be as follows:
- peat land and
Everything is taken in a ratio of 1: 1: 1: 1.
You can also purchase ready-made soil suitable for this type of plant.
Expanded clay is suitable as drainage.
After planting, cover the container with a film, bag or glass, put in a warm place, away from direct sunlight.
Before germination, it is necessary to periodically remove the film and ventilate the container. Seeds germinate quickly, in 25-30 days.
Transplant sprouts, 4-5 cm long, into pots and place in a well-lit place. After the plants get used to the sunlight, they can be rearranged on the windowsill.
How to grow bashful mimosa from an adult plant?
If the house already has mimosa, then to grow you need to follow these simple steps.
- To pollinate an adult plant - transfer pollen from one flower to another with a brush. Wait until the fruits appear.
- After drying, collect the pods. Store them in a paper bag in the refrigerator.
- In late February - early March is the time for planting - get the seeds out of the pods, pour them with warm water for 25-35 minutes.
- Prepare containers for planting - lay out drainage, fill with moist soil.
- Plant the seeds to a depth of 1 cm, cover with a bag, glass or foil. Move to a shady place.
It is important to avoid direct sunlight!
If the air temperature is between 20 and 25C, the first sprouts will appear in a couple of weeks or, by the deadline, in a month.
Transplant sprouts 4-5 cm long into separate glasses (plastic ones are suitable) and put in a warm place.
In late May - early June, transplant the grown sprouts into pots.
Some growers advise planting several sprouts in one pot.
Mimosa bashful rules of care and growing from seeds
Shy mimosa belongs to the genus Mimosa. Grows wild in Brazil and tropical America. Its height in nature can reach 0.5 meters.
In bashful mimosa, leaf plates are located on the stem in pairs, spines are present on the shoots and cuttings of the leaves. Nowadays, bashful mimosa is massively grown in greenhouses, as an annual plant.
Shy mimosa can be propagated by cuttings and seeds.
Many people like not only to grow it on the windowsill, but also to play with it, as it noticeably moves the leaves when you lightly touch them. Shy mimosa is grown in culture as an annual flowering plant. She has erect shoots, in height it can reach 0.70 m.
Flowers are formed with a diameter of 20 mm lilac-pink, in summer, at the ends of the shoots. Shy mimosa is a moisture-loving plant that negatively relates to drafts. A mixture of peat, turf, sand and humus taken in equal proportions is suitable as a substrate for shy mimosa.
Coarse perlite, sand and polystyrene can be used as baking powder. It is also worth adding bone meal to the potting mix for added nutritional value. For feeding, it is recommended to use a complex fertilizer for flowering plants.
Pollination can be carried out independently with a brush or soft cotton swab, transferring pollen from the stamens of one flower to the pistil of a neighboring one.
After pollination, a pod with seeds is formed, when the pod is fully ripe and dry, it must be torn off and placed in a paper signed envelope until spring. In the spring, separate the seeds from the pod and sow after soaking.
Mimosa seeds, bashful in shape, resemble a flattened pea, the seeds have a dense glossy peel. It is recommended to sow bashful mimosa seeds in early spring in loose soil in grooves, followed by planting at the stage of 2 true leaves.
For the germination of bashful mimosa seeds, a room with a temperature of about 20 - 26 degrees is necessary. The soil must be moistened and, after sowing, covered with a transparent oilcloth to create a microclimate with high humidity. Sowing is superficial, or it is allowed to sprinkle it with a small substrate half a centimeter thick.
After sowing, it is recommended to press the seeds against the soil to ensure that the seeds are in close contact with the soil. Seedlings appear after seven days.
At the beginning of development, bashful mimosa needs warmth, light and high humidity of about 80%. The soil should be moist, but not waterlogged.
Waterlogging can provoke a disease called Black Leg, therefore a drainage layer and a sterile substrate are desirable, if there are doubts about the sterility of the soil, it is recommended to spill it with a solution of potassium permanganate.
It is better to provide natural lighting on the window sill from the east or west side. It is recommended to cover the mimosa from the intense rays of the sun to prevent burns.
After reaching the seedling growth of 5 cm, it is necessary to begin to gradually get used to it to the open street air on the balcony or loggia. The seedlings do not tolerate drought, from this they can discard foliage.
In addition to timely irrigation, you can pamper mimosa by spraying with warm water. It slowly adds mimosa to its growth. The stem is reddish in color.
Bashful mimosa has one attractive feature, with a light touch, its feathery foliage instantly folds along the main vein, and the stalk goes down. This plant acquires the same unsightly appearance at sunset. In the morning, the bashful mimosa straightens up.
Diseases and pests
The plant can be affected by various ailments. Most often, their appearance is caused by non-compliance with the rules of agricultural technology. So, noticing that flower drops leaves, it can be assumed that the grower was unable to provide regular watering.
Observing yellownessformed on the leaf plates, or paying attention to the leaves that do not open when the day comes, it is worth reducing the frequency of watering, since all these signs indicate waterlogging of the soil.
When a flower is deficient in light, then they talk about it stretching shoots, their loss of elasticity... Sometimes, with poor access to light or low temperatures, the plant does not bloom.
Often, this culture is affected by harmful insects. Its most common enemies include several pests.
These are miniature bugs that love to feast on the juice of tender foliage. Aphid colonies can be seen on the bottom of the leaf plate or at the top of the stems. PDue to the destructive influence of these insects, the leaves become covered with a sticky bloom, the tops curl up, and development stops.
If the grower noticed the problem in time, and there are not so many individuals yet, then to protect the plant, you can treat it with soapy water. If the flower managed to hit the whole hordes of aphids, then spraying with Permethrin products, as well as Fitoverm or Agravertin preparations, can help.
When treating, it is important to eliminate twisted branches damaged by insects.
Escaping plant mimosa bashful, (very interesting)
Among the flowers that appear in abundance on the eve of the spring holiday on March 8, there are huge armfuls of plant twigs with beautiful golden inflorescences and a delicate pleasant scent. It is habitually (and mistakenly) called "mimosa". But this is not mimosa at all - these are flowering brushes of silver acacia (Acacia dealbata), a low evergreen tree.
The real mimosa is the bashful mimosa (Mimosa pudica). Its homeland is the distant country of Brazil. This is an unusually interesting and beautiful plant from the legume family (mimosa subfamily).
Shy mimosa is famous not for its appearance, but for its interesting property to fold its leaves when you touch them, for example, with a light snap of your finger. This is due to the presence of sensitive hairs at the base of its leaves that respond to touch, and, due to a change in turgor, this leads to folding of the leaves. Again, they open only after 30-60 minutes. The leaves of the plant fold by themselves at night and unfold again with the first rays of the sun.
The sensitivity of the bashful mimosa has become proverbial. The ability of its leaves to instantly fold not only at night, but also with mechanical irritation, and then slowly return to their previous state is literally amazing.
There are about 500 species of mimosa on the globe, most of which are common in tropical America and are represented by herbs, shrubs and trees.The name of the genus comes from the Greek word mimos - "mime", "actor" and reflects the ability of the plant to "play". But only a few species show their characteristic reaction to touch, among them - the beloved bashful mimosa.
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 made it possible to assume the endogenous origin of biological rhythms to which the movements of the leaves of the plant were confined. De Meiren suggested that these rhythms may have something to do with the alternation of sleep and wakefulness in humans.
Decandol in 1832 determined 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.
Indoors, it is grown as an annual plant, but in its homeland it is a branched thorny shrub. It is an evergreen shrub (from 0.6 to 1 m in height) with pubescent, straight thin shoots and small feathery oval leaves of a delicate green color.
In the summer, he pleases us with flowering. The leaves of mimosa are double-pinnate, consisting of numerous oblong-oval leaves. The flowers are small, twisted into fluffy axillary spherical inflorescences with numerous purple stamens exposed on long filaments, located at the ends of the shoots. Pinkish-purple tubular mimosa flowers are collected in capitate inflorescences. The fruits are articulated beans.
Due to the amazing ability of the bashful mimosa leaves to quickly fold when touched, every self-respecting botanical garden considers it necessary to have this unusual plant in its collection. From the botanical gardens, mimosa came to our homes. The touchy mimosa is often found in warm regions of the world as a weed plant. You can try sowing mimosa seeds in the garden yourself, preferably in May, when the threat of return frosts has passed. With the right care, mimosa produces a lot of seeds, which allows you to maintain the culture of this plant for many years.
The speed of mimosa reaction to irritation is directly dependent on the ambient temperature, and the leaves do not fold as quickly if it is cool. The leaves of an old plant also do not react as quickly to irritation as the leaves of a young one.
In nature, the plant reaches 1 m in height (in one growing season), but in indoor conditions, as a rule, it rarely exceeds 0.5 m.

Caring for mimosa at room conditions
- Lighting. For normal growth and flowering, you need a lot of sun, but with shading from direct rays. An east, west and south window will do (you need curtains at noon here).
Content temperature. From spring to mid-autumn, it is important for a plant to maintain the temperature within 20-24 degrees, in winter it is better to arrange a cool content, at which the thermometer readings will be 15-18 units, but not lower.
Humidity. For mimosa, it is important that the moisture readings are around 60%. But due to the fact that the foliage is pubescent, spraying is not recommended, so it is worth raising the humidity in any other way: they put air humidifiers, vessels with water nearby, spray the air around the mimosa, or set a pot with a plant on wet expanded clay in a deep pan.
Watering. When caring for mimosa, it is advised to pay attention to the top layer of soil in the pot: if it is dry, then it should be watered. At the same time, in the period from the beginning of spring to the end of September, the plant is moistened abundantly, from October they begin to gradually reduce the amount of water that is irrigated, bringing them to moderate in the winter months. Filling the substrate or completely drying it negatively affects mimosa, in the first case, the root system will begin to rot, and in the second, the leaves will turn yellow and fade. Water is used only well-separated, for at least a day. You can use river or rain.
Fertilizers for mimosa. In order for the plant to feel normal, it is recommended to apply top dressing during the growing season and during flowering - from early spring to August. The frequency of drug use will be once every 10-14 days. Use means for flowering plants in liquid form.
Usually, mimosa soil is needed with medium acidity or slightly acidic. It is mixed on the basis of a universal commercial primer or made up of:
- river sand, turf, leaf humus and peat, the proportions of the constituents are taken equal
- clay-sod substrate, deciduous soil, river sand and peat (in a ratio of 2: 1: 1: 0.5).
Bashful mimosa is a herbaceous plant or undersized shrub that actively reproduces in favorable natural conditions, filling river banks and tropical rainforests. The largest "cluster" of bashful Mimosas in South America. The people called this species touchy. Delicate fragile leaves of the plant do not tolerate even a light touch. They immediately fold, like a book, and remain closed for several minutes. The reaction of "embarrassment" occurs in the evening, as well as when exposed to any stimulus, for example, a sharp change in temperature. If the leaves are very often negatively affected, they may become too weak and sag.
In summer, Mimosa blooms with beautiful lilac-pink flowers, which form lush inflorescences-heads, not exceeding 2 cm in diameter. After a couple of days, they begin to fly around. They are immediately replaced by new ones, and so on for several weeks.
It should be borne in mind that the plant does not tolerate tobacco smoke well. Being in a smoky room, it begins to lose leaves.
In addition, Shy Mimosa is a danger to pets and small children - it is poisonous! Therefore, it is necessary to think over its placement so that access is limited!
A compact bush of such a Mimosa, reaching a maximum of 50 cm in height, will fit into any interior.
