Mimosas, commonly known as sensitive plants, are a miracle of nature. While it has many virtues as a houseplant, with its feathery compound leaves and pretty puff flowers, it’s the stunning leaf movement that makes this tropical plant so charming: the leaflets snap together at the touch of a button!
Native to the tropics of Central and South America, the mimosa is a creeping shrub or short-lived perennial often referred to as a “sensitive plant” because of its fascinating leaf movements when touched. The leaves of delicate plants are lined with tiny hairs that respond strongly to touch, temperature and movement and fold inward when triggered. The plant also closes its leaves at night. This response to various forms of stimuli is part of this plant’s natural defense mechanism. The delicate plant has delicate fern leaves and light purple flowers that resemble small pompoms. Young plants grow tall, but quickly develop an outward-crawling growth habit. While this delicate plant is hardy in zones 7 through 13 and is sometimes grown outdoors in these areas, it is more often grown as an excellent low-maintenance houseplant. It should be planted with caution outdoors, as it can easily escape and become naturalized, as it does in some southern states.
Sensitive Plant Care Delicate Plants
Sensitive plants (Mimosas) are a low-maintenance flowering plant in the legume family (Fabaceae). With plenty of light and plenty of water, even hobby houseplant lovers can enjoy the delicate foliage and unique movement of this sensitive plant at home. Unlike the Venus flytrap, this sensitive plant closes its leaves in complete self-defense. It is not carnivorous.
As landscape plants, the delicate plant is most often used as a sunny ground cover, but this requires monitoring to prevent rampant spread. Individual plants are short-lived, but they are easy to self-seek and volunteers can reach their maximum height in a single season.
As a houseplant, the sensitive plant wilts quickly after flowering, which is why it is usually planted annually and replanted from seed each year. Potted plants lose their appeal after about two years.
Sensitive Plant Introduction
Native to tropical South and Central America, this sensitive plant is a creeping herb or shrub with prickly stems and branches and belongs to the legume family, which means it is related to peas, beans, and legumes.
The plant’s delicate fern foliage consists of pairs of rectangular leaves with tiny hairs on their surfaces and edges. These hairs are very sensitive to touch, movement, and temperature, and when stimulated, pairs of leaflets come together in a fan-like motion.
This delicate plant produces delicate clusters of pale pink or lilac flowers in midsummer to early fall that resemble fluffy pom-poms as hundreds of filaments form these small spherical flowers. They develop into flat pods, each containing one to six seeds.
While this delicate plant is often grown as a perennial in nature, it is often treated as an annual when grown as a houseplant, as the plant tends to spoil after flowering. However, if you harvest seeds, you can quickly and easily grow new plants from them.
The scientific name Mimosa Pudica is derived from the Greek for “mime” and the Latin for “shy” and refers to the way the leaves respond to stimuli, as if the plant were shy and physically flinched when disturbed.
What is the abnormal movement of plants?
Plants do not move from one place to another, but they also exhibit movement in response to external stimuli. Plants exhibit different types of movement. It may or may not be a growth movement. This article is about nose movements in plants, their types and examples.
We know that plants are fixed in one place and their roots are in the ground, so they cannot move from one place to another. They usually do not exhibit motion, but when subjected to some stimuli such as light, gravity, chemicals, water, and touch, movement of individual parts or organs of plants (such as shoots, roots, leaves, etc.) is possible. These movements are likely under the influence of stimulants caused by plant hormones. In this article, we will discuss one type of plant movement, H. Nasty movement, this is a movement independent of growth.
How To Care For A Delicate Plants
Sensitive plants are not very shade tolerant. They thrive in eight hours of sunlight and tolerate partial shade, but do not do well in full shade. When growing indoors, the ideal location is in front of or next to a bright, sunny window. If the leaflets remain closed during the day, this indicates that the plant is not getting enough light.
Rich, well-drained soil is ideal for a delicate crop in the landscape; its roots cannot survive in heavily compacted soil. Amend the soil with peat moss to improve drainage. In their natural environment, sensitive plants live on nutrient-poor soils. Therefore, it does not require overly nutrient-rich soil or frequent fertilization.
Commercial potting soil is an excellent growing medium when grown as a houseplant.
For sensitive plants, keep the soil consistently moist but not waterlogged. Delicate plants cannot tolerate wet feet and can develop root rot if standing in too much water. Be sure to water sensitive plants once the top of the soil begins to dry out. Water sensitive plants a little in winter.
Temperature and humidity
Sensitive plants can be grown in zones 7 through 13 as short-term outdoor perennials or shrub groundcovers, but are most often grown indoors as potted plants. Potted specimens thrive at a typical room temperature of 65 to 75 degrees. Sensitive plants enjoy moderate to high humidity. Unless your home is particularly dry, average home humidity should be sufficient for sensitive plants. In areas with particularly dry winter air, use an air humidifier nearby or place delicate planters on gravel trays filled with water to increase humidity.
When grown as a potted plant on the patio, the delicate plant works best when brought indoors when temperatures are outside the ideal 65-75 degree range.
Sensitive plants grow naturally in nutrient-poor soil, so fertilization is usually not required. However, if you prefer, you can give your plants an extra boost during the growing season by applying a half-diluted potassium-rich liquid fertilizer every few weeks. Be sure to water sensitive plants before fertilizing to avoid burning the delicate roots.
Types of Mischief in Delicate Plants
There are five nasty movements in plants.
1. Earthquake movement:
This type of movement is caused by mechanical stimuli such as shock, touch or contact, fast-moving wind, raindrops, etc. Seismic motion was observed in stigmas, stamens and leaves in certain parts of the plant. For example: Plant Mimosa, Biophytum sensivum, Neptunia, etc.
2. Photon movement:
The random motion of a part of a plant, usually in a petal, in response to light is the motion of photons. The stimulus in Photonasty is light. Many petals open during the day and close at night in response to the intensity of the light. This is the growth motion of a plant and an example of the motion of photons. For example: dandelion flower, moon flower, nocturne flower, etc.
3. Thermal exercise:
This movement in plants occurs due to changes in temperature. The flowers of the plant open when the temperature rises and close when the temperature drops. Sometimes thermal motion is also related to photon motion. The reaction mechanisms of both are related to growth, changes in turgor pressure at the top and bottom of petiole, and leaves.
4. Night terrors:
This movement is caused by changes in light and temperature. It is also called sleep exercise. It can be divided into photon motion and thermal motion. It is present in beans. Flyers are folded in the evening and opened in the morning.
5. Thigmonasty Movement Delicate Plants:
The non-directional movement of plants in response to contact with an object is called thigmonasty movement. In the leaves of carnivorous plants such as sundew and Venus flytrap, tentacles exhibit different movements when they come into contact with insects. The stimuli of the insect’s touch are transmitted throughout the leaf, and all the tentacles are bent over the insect.
From the above article it is clear that plants do not exhibit movement, i.e. they do not move from one place to another, but certain parts of plants exhibit specific movements which may or may not be classified Movement for growth.
