The Elgon balsam plant grows up to a height of 2 meters and has a succulent stem. The leaves are green and velvet-like with serrated edges. The flowers of the plant are purple with white spots and have a tubular shape. The petals of the flowers are asymmetrical and arranged in a spiral formation.
Uses
Impatiens elgonensis T.C.E.Fr. is commonly used for medicinal purposes in Africa. The leaf extract is used to alleviate pain, treat colds, and relieve fever. It is also used to alleviate the pain and discomfort caused by insect bites and stings. The plant is also used in traditional African medicine to treat malaria and other infectious diseases.
The plant is also used for ornamental purposes, as it has attractive and colorful flowers. It is cultivated by gardeners and horticulturists as a garden plant and is often used in landscaping projects.
Light Requirements
Impatiens elgonensis T.C.E.Fr. typically grows in shaded areas with dappled sunlight. However, it can tolerate partial to full sun exposure if the soil is kept moist. It is important to protect the plant from direct sunlight as it can cause sunburn and damage to the leaves.
Temperature Requirements
This plant is native to the high altitude regions of East Africa and requires cool to mild temperatures for optimum growth. The ideal temperature range for Impatiens elgonensis is between 15°C to 25°C (59°F to 77°F). It is not tolerant of extreme heat or cold and can suffer damage or die if exposed to temperatures outside its suitable range.
Soil Requirements
Impatiens elgonensis T.C.E.Fr. prefers well-draining, fertile soils that are rich in organic matter. The soil should be moist but not waterlogged as this can lead to root rot. A pH range of 5.6 to 6.5 is ideal. Amending the soil with compost or aged manure before planting can improve the soil quality. The plant can also benefit from regular applications of a balanced fertiliser during the growing season.
Cultivation Methods
Impatiens elgonensis T.C.E.Fr. is a beautiful, flowering plant that requires a few specific cultivation methods to thrive. To begin with, it prefers partial shade and a moist, well-drained soil. It also needs protection from the wind and temperatures below 50°F. Plant the Impatiens elgonensis T.C.E.Fr. in spring, after all danger of frost has passed.
Watering Needs
To ensure healthy growth and flowering, Impatiens elgonensis T.C.E.Fr. requires adequate watering. The soil should remain moist but not waterlogged, as excess water can lead to root rot and other fungal diseases. Water regularly, especially during dry spells and heatwaves, and always water the soil directly, not the foliage.
Fertilization
Proper fertilization helps to promote healthy growth and abundant flowering in Impatiens elgonensis T.C.E.Fr. Use a balanced, water-soluble fertilizer every two weeks during the growing season, following the package instructions for dilution and application. Be careful not to over-fertilize, as this can lead to leggy growth and fewer flowers.
Pruning
Impatiens elgonensis T.C.E.Fr. benefits from occasional pruning to promote bushier growth and maintain a neat, compact shape. Pinch back the tips of the stems once or twice during the growing season to encourage lateral branching. Deadhead regularly, removing spent flowers and seed pods to prolong blooming. Trim back any leggy or damaged growth as needed.
Propagation of Impatiens elgonensis T.C.E.Fr.
Impatiens elgonensis T.C.E.Fr. can be propagated through both sexual and asexual methods.
Sexual Propagation
The plant produces small, green capsules that contain tiny seeds. These seeds can be harvested for planting, but it is important to note that they have a very short viability period. If not planted soon after harvest, they may no longer be viable.
To plant the seeds, it is best to use a germination tray or pot filled with well-draining soil. The seeds should be sprinkled on the top of the soil and lightly covered. They should be kept moist but not overly wet and placed in a warm, brightly lit space.
Approximately two to three weeks after planting, the seeds should start to sprout, and the seedlings can be transplanted into individual pots.
Asexual Propagation
Impatiens elgonensis T.C.E.Fr. can also be propagated asexually through stem cuttings. This method is especially useful for plants that have desirable traits that you want to replicate.
To propagate through stem cuttings, take a cutting that is at least several inches long from the parent plant, making sure to take cuttings from healthy, disease-free plants. Remove the lower leaves of the cutting and dip the end in rooting hormone. Insert the cutting into well-draining soil and keep it moist but not overly wet. The cutting should be placed in a warm, brightly lit space, but out of direct sunlight.
Within two to three weeks, new growth should appear, indicating that the cutting has successfully rooted. Once the plant has established roots, it can be transplanted into an individual pot.
Disease Management
Impatiens elgonensis T.C.E.Fr. is susceptible to various diseases that can cause damage and wilting of the plant. Here are some common diseases that might affect the plant:
- Downy Mildew: This disease causes grayish-white mildew to form on the underside of leaves, leading to distorted growth and yellowing of leaves. To manage this disease, remove and destroy infected plants, keep the foliage dry, and use appropriate fungicides.
- Verticillium Wilt: This soil-borne fungal disease causes the leaves to wilt, turn yellow, and eventually die. To prevent this disease, avoid planting Impatiens elgonensis in infected soil, and use appropriate fungicides.
- Cercospora Leaf Spot: This fungus causes brownish-black spots with yellow halos to form on the leaves, leading to defoliation. To manage this disease, remove and destroy infected plants, keep the foliage dry, and use appropriate fungicides.
Pest Management
Impatiens elgonensis T.C.E.Fr. is also susceptible to various pests that can cause significant damage to the plant. Here are some common pests that might affect the plant:
- Aphids: These small, soft-bodied insects suck the sap from young leaves and shoots, causing stunted growth and deformation of the plant. To manage this pest, remove affected plant parts, use appropriate insecticides, and encourage natural predators such as ladybugs.
- Whiteflies: These tiny, sap-sucking insects can cause yellowing and falling of leaves, as well as the spread of viral diseases. To manage this pest, use appropriate insecticides, sticky traps, and encourage natural predators such as parasitic wasps.
- Spider Mites: These tiny mites feed on the underside of leaves, causing yellowing and stippling of the foliage. To manage this pest, prune infested branches, use appropriate miticides, and keep the plant well-hydrated.
