Origin
Impatiens erecticornis R.Wilczek & G.M.Schulze, commonly known as Bonn's Balsam or Erect Bonnwort, is a flowering plant that belongs to the family Balsaminaceae. It is native to the Democratic Republic of the Congo in Central Africa, specifically in the Lomami River basin.
Common Names
The plant is known by various common names across different regions where it grows. Some of the most common names include Bonn's Balsam, Erect Bonnwort, Lomami Jewelweed, and Lomami Impatiens.
Uses
Impatiens erecticornis is not only an essential component of Congo's flora but also an important medicinal plant. Studies have shown that the plant has anti-microbial, anti-cancer, and analgesic properties. It is used to treat various ailments, including wounds, skin diseases, and fever. Indigenous people in the region also use it to treat infertility as it contains compounds that stimulate ovulation.
The plant is also grown for ornamental purposes as it produces attractive, tubular flowers that vary in color from white to pale pink, pale lavender, or light purple. Gardeners often grow it as a cover crop in shady areas to create a beautiful groundcover.
General Appearance
Impatiens erecticornis is an herbaceous plant that grows up to 30 cm tall. Its stem is slender and erect, and it branches out near the top. The plant has ovate to lanceolate leaves that are oppositely arranged and up to 6 cm long. The flowers are tubular and borne in clusters of 2-6 in the axils of the leaves. They measure about 2 cm long and have five petals that are either pale pink, pale lavender, or light purple. The fruit is a capsule that explodes when touched, dispersing the seeds up to several meters away.
Light Requirements
Impatiens Erecticornis thrives in shaded areas and does not tolerate direct sunlight. It requires bright but indirect light conditions to grow optimally. Too much sunlight can burn its leaves which will alter its photosynthetic process and lead to its decline. On the other hand, too little light will cause its stems to become leggy and weak.
Temperature Requirements
The plant is native to tropical climates, and therefore prefers warm temperatures to grow healthy. It can tolerate temperatures ranging from 18°C to 25°C during the day and 16°C to 21°C at night. However, the temperature should not drop below 10°C as the plant does not tolerate cold temperatures.
Soil Requirements
Impatiens Erecticornis is not too selective about soil type but requires well-drained soil that can hold moisture. It thrives in soils with high organic matter content, which makes them rich in nutrients and enhances water retention. The plant requires moderate soil pH ranging from 5.5 to 7.5, and it’s essential to avoid soil with a high content of salts and heavy metals.
Cultivation
Impatiens erecticornis is a tropical plant that grows well in warm and humid conditions. It requires a well-draining soil mix with equal parts of peat moss, perlite, and vermiculite. The plant needs partial shade to thrive, and it's important to avoid direct sunlight. It can be grown outdoors in USDA plant hardiness zones 10 and 11, but it's best to grow it indoors as a houseplant in colder regions.
Watering Needs
Impatiens erecticornis needs to be regularly watered to keep the soil moist but not waterlogged. It's essential to avoid overwatering the plant as it can cause root rot. The plant also requires high humidity levels, especially during the growing season. One way to increase humidity is to mist the plant with water or place a tray of water near the plant.
Fertilization
Impatiens erecticornis can benefit from regular fertilization during the growing season, spring through summer. A balanced liquid fertilizer can be applied every two weeks or as per the instructions on the label. It's important not to over-fertilize the plant as it can burn the roots.
Pruning
Impatiens erecticornis can quickly become leggy or untidy if not pruned regularly. The ideal time to prune the plant is in early spring before the growing season begins. Pruning will encourage bushier growth and promote flowering. It's important to use sharp and clean pruning shears and cut the stems just above a node. Removing spent flowers and yellowed or damaged leaves will also keep the plant looking tidy.
Propagation of Impatiens erecticornis R.Wilczek & G.M.Schulze
Impatiens erecticornis R.Wilczek & G.M.Schulze can be propagated through various methods which include:
Seed Propagation
Seeds of Impatiens erecticornis R.Wilczek & G.M.Schulze must be collected when they are fully ripe and dark in color. The seeds can then be sown in seed trays filled with moist potting mix. Cover the seeds with a thin layer of soil and water them gently. Keep the soil moist until the seeds germinate, which usually takes around 2-4 weeks. Once the seedlings have developed two to three leaves, they can be transplanted into larger pots or directly into the garden.
Cuttings Propagation
Impatiens erecticornis R.Wilczek & G.M.Schulze can be propagated from cuttings as well. Cut a healthy stem of the plant about 10 cm long with a sharp, sterilized knife. Remove the lower leaves and dip the cut end in rooting hormone before planting it in a pot filled with moist potting mix. Place the pot in a warm, shaded area and water it regularly. The cuttings should root in approximately 4-6 weeks.
Division Propagation
Impatiens erecticornis R.Wilczek & G.M.Schulze can also be propagated through division. Decide which clump you want to divide and gently lift it from the soil with a garden fork or spade. Shake off any excess soil and gently separate the root ball into two or more sections, making sure that each section has enough roots and shoots. Plant each section in a pot with fresh potting mix and keep it moist until new growth emerges.
Disease and Pest Management for Impatiens erecticornis R.Wilczek & G.M.Schulze
Impatiens erecticornis R.Wilczek & G.M.Schulze is a rare species of Impatiens plant that is native to Cameroon. Despite its natural resistance to some pests and diseases, it is still susceptible to others. Here are some common diseases and pests that may affect Impatiens erecticornis and ways to manage them:
Fungal Diseases
One of the most common diseases that can affect Impatiens erecticornis is fungal diseases. These diseases can cause leaf spots, stem rot, and wilting. To prevent fungal diseases, make sure to avoid overwatering and keep the soil well-drained. Additionally, avoid watering the plant from above, as this can cause water to sit on the leaves and create an environment for fungi to grow.
If your plant does develop a fungal disease, remove the affected leaves and dispose of them. Additionally, make sure to keep the soil as dry as possible, as this can slow the spread of the disease. Some fungicides may also be effective in controlling fungal diseases, but be sure to follow the manufacturer's instructions carefully.
Aphids
Aphids are small insects that can cause damage to Impatiens erecticornis by feeding on the sap of the plant. This can lead to stunted growth, yellowing leaves, and curling leaves. To manage aphids, you can try using an insecticidal soap or neem oil. Another method is to simply blast the aphids off the plant with a strong spray of water.
Spider Mites
Spider mites are another common pest that can affect Impatiens erecticornis. These tiny insects live on the underside of leaves and feed on the plant's sap. This can cause yellowing and stippling on the leaves of the plant. To manage spider mites, you can try using a miticide or insecticidal soap. Another method is to regularly mist the plant with water to create a humid environment that is less hospitable to spider mites.
Thrips
Thrips are small, slender insects that can cause damage to Impatiens erecticornis by feeding on its leaves and flowers. This can cause the leaves to become distorted and the flowers to become discolored. To manage thrips, you can try using an insecticidal soap or neem oil. Another method is to remove any weeds or grass from around the plant, as these can provide a habitat for thrips.
By following these tips, you can help keep Impatiens erecticornis healthy and thriving. Remember to monitor your plant regularly for signs of pests or disease and act quickly if you notice any issues.
