Overview
Mimosa schomburgkii Benth., also known as Schomburgk's sensitive plant, is a flowering plant native to South America. It belongs to the family Fabaceae and the genus Mimosa. This plant is named after Sir Richard Schomburgk, a German explorer who collected this plant in Guyana during the mid-19th century.
Description
Mimosa schomburgkii has a delicate, fern-like foliage with small, pink, globe-shaped inflorescences. The plant grows up to 1-2 meters tall, with a spread of approximately 1 meter. Its foliage is bipinnate, with numerous small leaflets arranged symmetrically on either side of a central axis. The plant's leaves have a feathery appearance and fold together when touched, an interesting characteristic common to plants in the Mimosa genus.
Common Names
The plant is commonly known as Schomburgk's sensitive plant because of its touch-sensitive foliage. Other names include Mimosa schomburgkii, pink sensitive plant, and shyness plant.
Uses
The plant is primarily grown as an ornamental plant due to its attractive foliage and distinctive, delicate flowers. Its touch-sensitive leaves make it an interesting conversation starter and are often used in sensory gardens. Additionally, the plant has been used in traditional medicine to treat various ailments, such as diarrhea and inflammation, due to its antibacterial and anti-inflammatory properties. However, more research is needed to support these claims.
Light Requirements
Mimosa schomburgkii Benth. requires full sunlight exposure for healthy growth and development. This species thrives in areas with open canopies or direct exposure to sunlight. Insufficient light may result in stunted growth and reduced flowering.
Temperature Requirements
Mimosa schomburgkii Benth. prefers warm temperatures ranging from 20°C to 35°C. Extreme cold or freezing temperatures can severely damage or kill this plant. In areas with cold winters, it is advisable to grow them in greenhouses or protected areas.
Soil Requirements
This species prefers well-drained soils with neutral to slightly acidic pH levels ranging from 6.0 to 7.5. The ideal soil type for Mimosa schomburgkii Benth. is loamy soil that is rich in organic matter and essential nutrients. This plant cannot tolerate waterlogged soils, and the soil should be kept moist but not overwatered. Regular fertilization can help to promote healthy growth and enhance flowering.
Cultivation of Mimosa schomburgkii Benth.
Mimosa schomburgkii Benth. thrives in tropical and subtropical climates, and it grows well in most types of soil, including clay, loamy, and sandy soils. Choose a planting location that offers plenty of sunshine and shelter from strong winds. The best time to plant mimosa is during the rainy season when the soil is moist and its roots can establish faster.
Watering Needs
Mimosa schomburgkii Benth. requires moderate watering. Young trees require frequent watering until the roots become established. During the rainy season, you may not need to water the trees frequently, but during the dry season, ensure that you water the trees once every two days.
Fertilization
To promote healthy growth, fertilize the trees with a balanced fertilizer before the rainy season. This promotes healthy root growth, healthy leaves and flowers, and a general healthy appearance of the tree. During the dry season, you can apply a slow-release fertilizer, but avoid applying high-nitrogen fertilizers, as this can cause excessive growth of the tree.
Pruning
Mimosa schomburgkii Benth. does not require regular pruning, but you may need to remove the dead or diseased branches to promote healthy growth. When pruning, use sharp pruning shears and cut the branches at the base. Avoid pruning more than one-third of the tree at once, as this can create a shock to the tree.
Propagation of Mimosa schomburgkii Benth.
Mimosa schomburgkii Benth. is commonly propagated through seeds or stem cuttings. Here's a detailed explanation of each method:
Propagation through seeds
The seeds of Mimosa schomburgkii Benth. should be sown in a well-drained potting mixture, kept moist and warm, and exposed to bright light. It is best to sow the seeds soon after collecting them for best results. The germination period tends to be between two to four weeks. Once the seedlings appear, they should be thinned to promote healthy growth.
Propagation through stem cuttings
Stem cuttings are used to propagate Mimosa schomburgkii Benth. during the growing season. Taking a cutting should be done with a sharp, sterilized knife, from a young shoot that is healthy and robust. The cutting should be about 10-15 cm long, taking care to use a rooting hormone to increase the cutting's chances of survival. It is best to dip the cutting in rooting hormone, tap off any excess, and plant it in a well-drained potting mix. The stem cutting should be placed in a warm, sunny area and kept adequately moist, and it should develop into a new plant within a few weeks.
Propagation of Mimosa schomburgkii Benth. can be accomplished with the methods mentioned above. With the right conditions and care, Mimosa schomburgkii Benth. will produce healthy specimens.
