The plant typically grows up to 60cm tall, and it has a spread of up to 1m wide. The stems are fragile and succulent, with a greenish hue. The leaves are alternate and ovate in shape, with serrated edges and a dark green surface. The flowers are borne singly or in pairs on long stalks that arise from the leaf axils, and are a conspicuous deep magenta-pink color. The fruit is an erect capsule containing many black seeds that are explosively released when ripe.
Common Names:
The plant is commonly known as Impatiens, African Balsam or Busy Lizzie, in recognition of its ability to produce an abundance of flowers.
Uses:
Like many other species of the Impatiens genus, Impatiens brachycentra has both ornamental and medicinal uses. In landscaping, it is used mainly as a bedding plant in gardens or as a potted specimen for patios or verandas. It has also been used as a cut flower in floral arrangements.
In traditional African medicine, the plant extract has been used to treat various ailments such as skin disorders, wounds, fever, and respiratory infections. Its sap is also known to contain antihistamines that can alleviate allergies and reduce itching caused by insect bites.
However, it should be noted that the plant is toxic to some animals, including cats and dogs, and may cause skin irritation in some people. Therefore, caution should be exercised when handling it.
Light Requirements
Impatiens brachycentra grows best in partially shaded areas. It can tolerate some direct sunlight but it should be avoided during the hottest part of the day. Placing the plant under a tree canopy or a structure that provides shade can be beneficial.
Temperature Requirements
This plant species thrives in warm and humid conditions. Temperatures between 20°C to 25°C are ideal for its growth. It can tolerate cooler temperatures but the growth rate will be slower. Frost must be avoided as it can severely damage or even kill the plant.
Soil Requirements
Well-drained but moist soil is essential for the growth of Impatiens brachycentra. It is best to choose soil that's rich in organic matter and slightly acidic with a pH range of 5.5 to 6.0. The soil should also be able to retain moisture without becoming soggy, therefore proper drainage is crucial. Ample use of mulch can help retain moisture and also regulate soil temperature.
Cultivation Methods
Impatiens brachycentra G.M.Schulze & Launert is a hardy plant that thrives in well-drained soil with a pH range of 5.6-7.5. It prefers a partially shaded location with warm temperatures ranging from 60°F (16°C) to 80°F (27°C). This plant is typically propagated by seeds or cuttings, and it blooms from summer to fall.
Watering Needs
The watering requirements of Impatiens brachycentra G.M.Schulze & Launert vary depending on the season and environmental conditions. During the hot and dry months, it requires frequent watering to prevent the soil from drying out. However, in the cold season, it requires less water to avoid root rot. It's best to water the plant at the base rather than from above to keep the foliage dry.
Fertilization
Impatiens brachycentra G.M.Schulze & Launert requires regular fertilization to maintain optimum growth and blooming. Fertilize the plant every two weeks during the active growing season with a balanced fertilizer that has an NPK ratio of 20-20-20. Reduce the frequency of fertilization in winters or when you notice the plant's growth slowing.
Pruning
Pruning Impatiens brachycentra G.M.Schulze & Launert helps to promote bushy growth and maintain a desirable shape. Remove any dead, diseased or damaged foliage by cutting them at the base of the stem to encourage new and healthy growth. To maintain its shape and prevent it from spreading too wide, pinch the tips of new growth as needed throughout the growing season.
Propagation of Impatiens brachycentra G.M.Schulze & Launert
Impatiens brachycentra G.M.Schulze & Launert is a herbaceous perennial plant native to Tanzania. Its small, vibrant pink flowers and dark green foliage make it a popular choice for gardens and indoor spaces. If you're interested in propagating this plant, there are a few methods you can try.
Division
One of the easiest ways to propagate Impatiens brachycentra is through division. This method works best if the plant has become too large for its pot or if you're trying to create more plants for your garden.
To divide the plant, gently remove it from its pot or garden bed. Use a sharp, clean knife to cut through the root system, being careful to create smaller sections with at least one healthy stem and root system in each. Replant each section in its own pot or garden bed, keeping the soil evenly moist while the plants establish themselves.
Cuttings
If you only have access to one plant and want to create more, taking cuttings is a good option. Cuttings are sections of the plant that can be rooted and grown into new plants.
To take a cutting from Impatiens brachycentra, start by making a clean cut of a stem just below the node (the point where the leaf meets the stem). Remove the bottom set of leaves, leaving only a few at the top. Dip the cut end in rooting hormone to encourage root growth, and plant the cutting in a pot filled with moist potting soil. Cover the pot with a plastic bag to create a humid environment, and keep it out of direct sunlight. Roots should develop within a few weeks.
Seeds
You can also propagate Impatiens brachycentra from seeds, although this method can be more challenging. The plant produces small seed pods that burst open when mature, scattering the seeds. To collect the seeds, wait until the pods turn brown and begin to open, then gently remove them from the plant and allow them to dry completely.
Sow the seeds in a tray or pot filled with moist growing medium, covering them with a thin layer of soil. Keep the soil evenly moist and place the tray or pot in a warm, bright location. Seedlings should emerge within a few weeks, but be patient – Impatiens brachycentra can take several months to reach maturity.
Disease and Pest Management for Impatiens brachycentra
Impatiens brachycentra G.M.Schulze & Launert is generally a hardy plant that is resistant to most pests and diseases. However, when the plant is grown in unfavorable conditions, it becomes vulnerable to pests and diseases, which can reduce its yield and quality. Here is a list of common pests and diseases that affect Impatiens brachycentra and ways to manage them.
Common Diseases
1. Powdery Mildew: Powdery Mildew is a common fungal disease that appears as a white powdery substance on the leaves of the plant. It can reduce the yield and quality of the crop. To manage this disease, the affected plants should be sprayed with a fungicide, and the infected leaves should be removed and destroyed.
2. Verticillium Wilt: Verticillium Wilt is caused by a fungus that attacks the plant's roots and stem, causing them to wilt and die. To manage this disease, the infected plants should be removed and destroyed, and the soil should be fumigated before replanting.
3. Botrytis Blight: Botrytis Blight is a fungal disease that appears as a grayish-brown mold on the flowers and leaves of the plant. To manage this disease, remove the infected parts and spray the plant with a fungicide.
Common Pests
1. Spider Mites: Spider Mites are tiny pests that can cause the leaves of the plant to turn yellow and fall off. To manage this pest, spray the plants with an insecticide or a mixture of water and dish soap.
2. Aphids: Aphids are small, greenish bugs that are known to suck the sap from the plant, causing it to become stunted and damaged. To manage this pest, spray the plants with an insecticide or a mixture of water and dish soap.
3. Thrips: Thrips are insects that damage the plant by sucking the sap from the leaves and petals, causing them to become discolored and deformed. To manage this pest, spray the plants with an insecticide or a mixture of water and dish soap.
By being vigilant and regularly inspecting your Impatiens brachycentra, you can easily manage any disease or pest problems that may arise, and ensure that your plant thrives and grows to its full potential.
