How do mimosa trees reproduce

How to Grow a Mimosa Tree From a Seed | Home Guides

By Sasha Degnan Updated November 28, 2018

Valued for their fragrant pink flowers and airy foliage, mimosas or silk trees (Albizia julibrissin) are a subtropical species of deciduous tree widely grown throughout U.S. Department of Agriculture plant hardiness zones 6 through 9. They produce an abundance of long, pealike seed pods year-round, which may be harvested in autumn and used to propagate new trees. Mimosa seeds germinate quickly in warm conditions and will put on approximately 36 inches of growth each year. However, the hulls of the seeds are very hard and must be processed before sowing to ensure successful germination.


Mimosas attract hummingbirds, butterflies and bees to the landscape, but in some regions, they're considered to be extremely invasive and difficult to eradicate once established. Before you plant mimosas in your yard, contact your local county extension office to find out if they're invasive in your area.

  1. 1. Gather the Pods

    Gather mimosa tree pods in autumn after the pods darken and dry out. Snip the ends off with heavy shears. Pry open the pods and shake out the flat, dark-brown seeds.

  2. 2. Store the Seeds

    Put the mimosa seeds in a paper or cloth bag and store them until spring in a cool, dry location. Avoid using a plastic bag as it will trap moisture and cause the seeds to rot.

  3. 3. Prep the Seeds

    Prepare the mimosa seeds for sowing after the last spring frost. Rub the end of each seed with a nail file until a small, pale spot appears on the hull. Then soak the seeds in hot water for 24 hours before sowing.

  4. 4. Sow the Seeds

    Fill individual 5-inch biodegradable pots with a lightly moistened mixture of half sand and half loam. Sow one seed in each pot at a 1-inch depth. Spread a 1/4-inch-thick layer of sand over the soil.

  5. 5. Move the Pots Outside

    Set the pots outdoors against a south- or west-facing wall with full sun. Provide 75 F bottom heat with a propagation mat if the weather is cool and light shade at midday if daytime temperatures rise above 90 F.

  6. 6. Monitor the Moisture

    Carefully monitor the moisture level of the soil. Water to a 2-inch depth whenever the top 1/2 inch of soil dries out. Avoid overwatering or letting the soil dry out completely, which will cause the mimosa seeds to fail.

  7. 7. Watch for Germination

    Watch for germination one to three weeks after sowing. Grow the seedlings under the same conditions as during germination until they reach 3 inches in height and produce several mature leaves.

  8. 8. Transplant the Trees

    Transplant the mimosa trees into a permanent bed in autumn at least six weeks before the first frost. Choose a planting site with full sun at least 20 feet away from structures, utility lines and other trees. Plant multiple mimosa trees approximately 20 feet apart.

    Things You Will Need

    Mimosas thrive in a variety of soil types and textures and may be found growing along roadsides or in abandoned fields in poor to average soils in full sun, although they can tolerate partial shade. Until the trees are well-established in your landscape, apply water when the top couple of inches of soil are dry to the touch; reduce water in winter. Suppress weeds by applying approximately 3 inches of organic mulch evenly out to the tips of the branches, but don't allow the mulch to touch the base of the tree. Withhold fertilizer for the first two to three years and then have the soil tested to determine if fertilizer is necessary.

The Mimosa Tree Complete Guide

Gardening Tips For The Mimosa Tree

The Mimosa Tree is a stunning show of flower bursts, which are often compared to starbursts or fireworks. This small to medium-sized fast growing Mimosa Tree displays the most beautiful pink flowers in the depths of summer. Butterflies, bees, and hummingbirds will flock to these flowers, which show off bright, tight clusters of pink to yellow-tipped stamens. Frequently known as the “silk tree”, the stamens of the flower are reminiscent of silk threads. The Mimosa Tree has unique palmate leaves, which appear as tiny fronds similar to the leaves of palm trees or fern plants. Texture is a large aspect of why the Mimosa Tree has gained popularity throughout the United States. The 20 to 30 small leaflets provide a detailed background on which the bursting colors of the Mimosa flower blossom.

The Mimosa Tree is known by many other names throughout the world. Its Italian namesake, Filippo degli Albizzi, provides it a portion of its scientific name, Albizia julibrissin. The other part of the name is derived from a Persian word meaning “silk flower”. Commonly found throughout the world’s warmer climates, the Mimosa Tree is a popular ornamental flowering tree. It is also fast-growing, making it an irresistible choice for many homeowners. For gardeners hoping to provide dappled shade for smaller plants, the 20 to 25 foot tall Mimosa Tree provide the necessary height, shape, and leave density. It is always a beautiful addition to the garden.

These drought-resistant and fast-growing trees do produce beautiful flowers, which when coupled with its small fruit and leaves, can create the need for a clean-up routine. Well worth the clean-up and pruning, Mimosa Trees are positively beautiful when planted as either a central focal point in the yard or in a row as a border along entryways or fences. Enjoy the luscious pink blossoms in summer and the gentle shape throughout the year.

Quick Tips

Enjoy some quick tips here. For more complete information, read about these hints in more detail below.

Sunlight – Mimosa Trees prefer full sun; in drier regions, some partial afternoon shade for the tree may prove beneficial.

Soil – The adaptable Mimosa Tree prefers moist, well-drained acidic soil; however, the tree is often successful in a variety of other soil conditions.

Water – The drought-tolerant Mimosa Tree prefers at least an inch of water a week; however, it is able to withstand mild to moderate droughts with relative ease.

Pruning – Pruning should occur in winter, while the tree is dormant only after it is established (3 years). Remove dead or diseased wood.

The Best Places to Plant the Mimosa Tree

The Mimosa Tree, which originated in southwestern and eastern Asia, prefers the warmer climates. The tree is now commonly found throughout many regions of the world, and it can withstand brief cold spells.

In the United States, the Mimosa Tree prefers USDA Hardiness Zones 6 through 10, preferring the subtropical to tropical climates of much of the lower latitudes. Plant the Mimosa Tree in an area that receive full sun, though some partial shade, especially in the driest regions of the southwest, can be helpful to the water retention of the tree. The Mimosa Tree is best suited as an accent plant, where its ornamental beauty will not be lost. For many gardeners, this may mean a center-garden or center-yard spot. The Mimosa Tree can also be used to line entryways or driveways, and its uniform shape allows it to pair nicely with others in its species.

Mimosa Trees prefer the moist, well-drained soil typical of loam. With regard to pH, the tree enjoys slightly acidic soil. Despite these preferences, the Mimosa Tree readily adapts to various soil conditions. Water is not as much of a concern for the Mimosa Tree. In fact, short dry spells will not harm this tree since it is drought-resistant. Like most flowering trees, the Mimosa prefers at least an inch of water a week in the form of rainfall or irrigative services. If the region in which the tree is planted is prone to severe droughts, consider investing in an irrigation system that will not only help control the flow of water, but disperse it to the Mimosa during those truly hot, long-lasting droughts.

The Mimosa Tree is a beautiful ornamental plant. When considering planting locations, look for one where its beauty will shimmer!

Growth Rate and Mature Height

The Mimosa Tree is a small to medium sized ornamental tree. It is also exceptionally fast-growing. Expect the tree to quickly reach between 20 and 25 feet in height and 10 to 20 feet in width. The growth rate of the tree is fast, frequently earning the Mimosa Tree as much as 5 feet in a growing season!

Pests, Diseases, and Other Concerns

The Mimosa Tree is known to be a hardy, disease-resistant ornamental tree. Despite these benefits, there is one vascular fungal disease that can affect the growth of the Mimosa Tree. Mimosa Wilt is the most fatal of the diseases to impact the Mimosa Tree. The leaves of the Mimosa will yellow and wither before midsummer, often interrupting flowering. Many trees die quickly after wilting is observed, though most die branch by branch.

Diseased trees in advanced stages of the disease’s development may produce ooze from cracks in the trunk. Using a balance fertilizer can help to reduce the likelihood of the Mimosa developing this wilt. Water frequently and remove diseased wood.

Noteworthy Tips on the Mimosa Tree

– The Mimosa Tree has several cultivars that have become popular, including the ‘Summer Chocolate’ and ‘Ishii Weeping’.

– Mimosa Trees produce seeds that are enjoyed by many wild animals, including birds.

– In some regions of the world, such as Japan, the Mimosa Tree has been labeled ‘invasive’.

– Birds, butterflies, and honeybees will flock to the sweet nectar the Mimosa Tree produces, adding a wildlife scene to the garden environment.

– The seeds grow readily, which is part of the reason the tree has been labeled as invasive in some areas. Researchers are currently cultivating a non-seed bearing Mimosa cultivar that will be able to provide the same stunning beauty without the risks!

Mimosa: plant species | Cultivation of mimosa

For many Russians, especially older ones, the arrival of spring is associated with International Women's Day, when it is customary for all women to give flowers. The most luxurious bouquet for a women's holiday is a bunch of twigs with fragrant fluffy bright yellow flowers-balls. This flower is called mimosa.

A bit of history

This plant is native to Australia, the island of Tasmania. Here, in the most favorable conditions for its growth, individual representatives can reach up to 45 m in height. Over time, mimosa spread throughout the world. It appeared in Russia in the second half of the 19century and successfully spread along the southern part of the Black Sea coast. Initially, it was used for landscaping parks and squares, but quickly grew and today mimosa thickets can be found near the cities of Sochi, Tuapse, in Abkhazia. It is not only grown as an ornamental plant for outdoor cultivation, but also wild, along highways and highways. But the climate here is different from the Australian one, so the height of the plants does not exceed 12 m.

At the end of 19century, mimosa was also brought to France. And if in the Australian mountainous and hilly area it blooms in summer, then in Europe the beginning of flowering occurs at the end of winter - the beginning of spring. In many European countries, this period coincides with St. Valentine's Day, symbolizing love, spring.

Europeans fell in love with mimosa due to the aroma and beauty of flowers, as well as unpretentiousness in cultivation. As well as in the south of Russia, in Abkhazia this plant has perfectly mastered in the southern hilly regions of France. Here, in honor of this unusual flower, even a special festival is held - Mimosa Day. The capital of the holiday is the small town of Mandelieu-la-Napoule, since almost all of its inhabitants are actively involved in the cultivation of this plant. For 10 whole days, the city is immersed in festive bustle: processions, competitions, street concerts, dance and theater performances attract many tourists here.

There is even a beauty contest in honor of the mimosa. Its winner becomes the central figure of a bright, colorful parade-procession - the culmination of the festival. The parade takes place on the last Sunday of February, when unusual compositions assembled from bright fluffy flowers float through the streets of the town.

Types of mimosa

This amazing plant can be found not only in Australia and Europe. In the wild, mimosa species grow as trees and shrubs in Africa and South America. The name of this plant familiar to Russians is not correct. It belongs to the genus Acacia, which has more than 500 representatives with flowers of yellow, pink, cream shades.

The name of the whole genus comes from the Greek word akis, which translates as a point, because many species of trees and shrubs from this family have thorns on their trunks. Most often, African varieties are “armed” with them. But in American, Australian varieties, they are usually absent.

Despite such a variety of plants of this genus, two types of mimosas have become widespread in our country.

  • Silver locust
  • Shy mimosa
  • Temperature
  • Illumination
  • Watering

This is exactly the mimosa, bouquets from which Russians prefer to give their women in early spring. She has openwork leaves of a silvery, blue, or slightly greenish hue. Small flowers (fluffy yellow balls of numerous stamens) are collected in inflorescences - panicles.

In our country, silver acacia (or mimosa) usually grows as an evergreen shrub. Under more favorable conditions, for example, in the southern regions of Italy, France, it can take the form of a tree reaching 25 m in height with a dark gray smooth surface of the trunk. During flowering, such a tree is a very spectacular sight - a huge bright yellow crown-blanket, through which a huge number of openwork silver-green leaves peep through.

But in addition to trees and shrubs, there is also mimosa as a herbaceous perennial native to Brazil. The tropical flower is a distant relative of the acacia. Its height rarely exceeds 30-60 cm, but under especially favorable conditions it can reach 1.5 m. Like all acacias, it belongs to the legume family. Collected in spherical inflorescences, small pink, lilac flowers, after flowering, form a fruit - a bean. One pod can contain from 2 to 8 pieces of pea seeds.

Bashful mimosa received such an original name thanks to one amazing feature: at the slightest touch, the breath of the breeze, it folds and lowers its delicate delicate leaves. Then, after the "danger has passed", the leaves gradually open. Similarly, the plant reacts to any other impact: shaking, fluctuations in temperature, air, and so on. Moreover, even if the touch to the plant was a point, the reaction is almost instantly transmitted from leaf to leaf. Mimosa folds shy of its leaves before nightfall. However, you should not experiment unnecessarily and “disturb” the flower too often. After a while, he will "get tired" and the reaction will slow down.

Despite the fact that mimosa belongs to perennial flowering plants, in our country it is usually grown as an annual, because with the onset of cold weather, the flower sheds its leaves, loses its decorative effect, and stretches. At low winter temperatures, it can simply die.

Mimosa is often used as a medicinal plant in its natural environment. For example, the leaves have bactericidal properties and are used in the treatment of throat diseases, cuts, wounds. Root-based medicines help with dysentery, high fever, toothache, and accelerate labor activity.

Cultivation and care

Tenderness, fragility, sophistication of mimosa is a purely external manifestation. In fact, mimosa is quite unpretentious, undemanding to care for. The main condition is a mild, warm subtropical climate. In this case, it can be cultivated in open ground. But it is also grown indoors: greenhouses, greenhouses, winter gardens. It must be remembered that the plant has a negative attitude to the effects of tobacco smoke. This can lead to complete leaf drop.

The most comfortable mimosa vegetation temperature is within 20-24 degrees. In winter, adult plants easily tolerate small short-term frosts. But for young shoots, flowers, they can be fatal. In winter, when cultivating indoors, the temperature must be reduced to 10ºС.

Like all plants that came to us from the hot tropics, mimosa is not afraid of direct bright sunlight. She feels great in lighted areas, in bright, brightly lit rooms.

Acacias tolerate drought well, but during the growing season (spring, summer) they need regular moderate watering. Thankfully, she responds at this time to the daily spraying of the leaves with warm water. But in cold weather, waterlogging of the soil should not be allowed. You need to constantly monitor the soil moisture, ensuring timely watering even in winter.

Bush varieties are well molded, which allows them to be used for decorating plots. Plants do not impose special requirements on the soil, but when flowering, which can last at least 4 months, it is advisable to regularly feed the bushes with organic, mineral fertilizers, about 1 time in one and a half to two weeks. When grown in tubs, pots, and other containers in the warm season, they can be taken out into the open air.

Propagation of mimosa

Most shrubs "prefer" vegetative propagation methods. But acacia is quite difficult to grow from cuttings. However, with careful care, it can still be done. For this, semi-lignified shoots are selected. The procedure is carried out in the warm season, in late spring or summer.

Silver Locust and Shy Mimosa are easiest to grow from seed. This is done at the end of winter or in the first month of spring. Seed material is pre-treated with boiling water or soaked in warm water. And then planted in moist soil, composed of equal amounts of turf, sand, foliage, peat. The containers are covered with a non-woven material and placed in a warm, dark place until germination occurs. After the sprouts appear, they are seated in separate containers and brought out into the light.

propagation, planting and proper care of a houseplant

Mimosa is one of the most mysterious and unusual plants. Flower growers grow mimosa not only because of its tenderness - it is known for being able to move the leaves, fold and unfold them. Children especially love to watch the spectacle.

Moreover, the plant pleases the eye with fluffy and touching inflorescences. They decorate any room or greenhouse. Mimosa is famous for the fact that it looks favorably against the background of white materials or light flower arrangements. Growing a miracle of nature is easy. However, for this it is necessary to create certain conditions. The information will help the grower to properly prepare the soil for the plant and successfully grow the touchy mimosa.

Description of the plant

Mimosa is often confused with silver acacia - these are the branches that are usually given to women on March 8th. However, real mimosa has nothing to do with acacia and looks completely different. The homeland of the plant is South America, Brazil, East Asia and Africa. Mimosa grows on sunny hills in the humid tropics. It envelops quite large areas in wild habitats.

Mimosa is a shrub, tree or herbaceous plant, depending on the species and location.

Belongs to the mimosa subfamily. There are about 500 species. It is grown as an annual plant, as it loses its decorative effect over time.

Structural features of mimosa:

  • Greens form two-pinnate leaves, the surface of which is provided with receptors. Thanks to them, the plant feels danger and folds the leaves - they close.
  • Mimosa blooms in small inflorescences collected in spikes or a bunch, a head.
  • The color of the flowers is often pale purple with a pinkish tint.
  • Mimosa can reach one meter in height, some species stretch even higher.

Mimosa loves sunny color and high humidity. The cultivated plant species is Mimosa Shy - it is she who is grown everywhere at home or in the open field, if climatic conditions allow.

The ability of leaves to respond to changes in the environment has become the number one reason for growing mimosa. It is interesting to watch how the leaf quickly folds and also quickly unfolds. However, if the plant lives for more than a year, this ability is gradually lost, the response process slows down.

Creating Growing Conditions

Since the plant is native to the rainforests of South America, it needs similar growing conditions. Mimosa loves high humidity, warmth and sunlight. It is not recommended to breed a plant in open ground even in the south of Russia. Therefore, mimosa is often grown at home.

The room where the mimosa pot is to be placed must have constant sunlight. The plant can easily tolerate direct sunlight. However, young sprouts are accustomed to this gradually. If there is not enough light in the room, the mimosa will not grow, shed its foliage and die. Choose a room south or east.

The room must be constantly maintained at high humidity through regular sprinkling and watering.

Dry air can kill the touchy. Good drainage must be placed in the pots; a layer of expanded clay can be laid on the pallet, which will retain moisture. Many people place a pot of mimosa in moist peat for the same purpose - to retain moisture.

The temperature regime for the plant must be strictly observed, otherwise it will shed its leaves and will not grow. In summer, the air temperature should be 22 ° -26 °, in winter the minimum figure is 15 °, and the maximum is 22 °. If the temperature regime does not match, mimosa can get sick and die. To grow a plant, all conditions must be observed, otherwise the bashful beauty will not please with flowering.

Planting mimosa

Recommendations for planting plant seeds:

  • Use small containers with a diameter of 9 cm for planting seeds.
  • Fill them with a substrate of equal parts of leafy soil, humus, soddy soil and a little sand - half of one part.
  • The substrate should preferably be disinfected. Spill the soil with a solution of potassium permanganate.
  • Lay a drain in the bottom of the container.
  • Seeds are usually not buried, but pressed down to the substrate.
  • Cover the container with foil and place in a warm room.

Watch for sprouts under the film. As soon as they appear, it is advisable to ventilate the container, that is, open it for about half an hour. The measure will prevent the appearance of a black leg, which loves young shoots so much.

Seeds germinate in about 7-8 days.

Germination of mimosa is high. It is rare that inoculum fails to produce results. This usually happens when the seeds are stored incorrectly. When two full-fledged leaves are tied on the sprout, it can be transplanted into a permanent flowerpot with the same composition of the substrate. Only the components should already be in equal proportions. To sunlight sprouts accustom gradually. Exposed to open rays for a certain period of time and again removed to a shaded place. Be careful not to burn the leaves. Mimosa grows quite quickly, it needs to create all the conditions for this, in particular, proper care.

Proper care is the key to lush flowering

After planting mimosa in a permanent pot, feed the plant. A complex of mineral fertilizers for flowering plants is used. Dilute it twice as much as the dose indicated on the package. Before fertilizing, be sure to moisten the soil, otherwise the root system may get burned. The first feeding is carried out immediately after planting, the second and further every 2-3 weeks until August.

Watering Mimosa:

  • During the entire growing season, mimosa should be watered abundantly, but not flooded. Excessive watering, as well as drying out an earthen coma, will lead to the death of the plant.
  • Watering is carried out as the top layer of the substrate dries.
  • In addition to timely soil moistening, mimosa welcomes sprinkling procedures. They are held once a day in the summer.
  • For watering and spraying use only settled water at room temperature.

Mimosa does not like drafts and temperature changes. The plant can get sick and lose foliage. Do not overdo it with leaf twisting games. If you imitate a danger to a plant very often, it will weaken, grow and develop poorly. It is also necessary to monitor faded inflorescences and fallen leaves. The fact is that during flowering a lot of garbage is formed - pollen, flowers, leaves. All this can provoke an allergic reaction, if there is a tendency to this. Therefore, clean up the garbage after the beauty, so as not to start sneezing and crying from the abundance of pollen.

Reproduction of impatiens

Mimosa is propagated by seeds or cuttings. The first method is the most common, since the plant easily produces seeds. It remains only to collect them at the end of summer or autumn. Reproduction by cuttings occurs less frequently, as they sometimes do not take root. It is more expedient to purchase seeds or collect them from an already adult plant.

Seed material is stored all winter until April - the time for planting mimosa seedlings. The collected material is disinfected with a solution of potassium permanganate, dried and stored in a dark place for storage. Before planting, many flower growers soak the seeds. So they grow faster and better. Cuttings are cut from an adult plant - its upper shoots. They do it in the summer. Usually such a procedure is welcomed in the case of growing a plant in greenhouses, where growing conditions for mimosas are constantly maintained.

At home, seed propagation is more commonly used.

If the plant has already been purchased as a young sprout, do not rush to transplant it.
