Origin and Common Names
Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda, commonly known as Nyungwe balsam, is a species of flowering plant in the family Balsaminaceae. This perennial herb is native to Nyungwe Forest, Rwanda, where it grows in the moist, shaded understory layers of mountain forests.
General Appearance
Impatiens nyungwensis is a small, delicate plant that grows up to 30 cm tall. It has a thin stem with dark green leaves that are ovate and serrated. The plant produces beautiful pink flowers with a yellow center that bloom from mid-summer until the first frost.
Like other Impatiens species, Nyungwe balsam has an explosive seed pod that, when touched, bursts open to spread its seeds. This mechanism is where the genus name Impatiens comes from.
Uses
The medicinal properties of Impatiens nyungwensis are not known, but it is commonly grown as an ornamental plant. The attractive flowers make it suitable for use in a garden or as a potted plant. However, due to its limited distribution and conservation status, it is not readily available in the horticultural trade.
Impatiens nyungwensis is one of several Impatiens species found in Nyungwe National Park. The park is an important biodiversity hotspot and home to many threatened and endemic plant species. Conservation efforts are underway to protect the park and its unique flora and fauna.
Growth Conditions for Impatiens Nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda
Light Requirements: Impatiens nyungwensis is a shade-loving plant that thrives in diffused light. It cannot tolerate direct sunlight for long periods of time and must be protected from the harsh rays of the sun.
Temperature Requirements: Impatiens nyungwensis grows well in temperatures ranging from 18°C to 25°C (64°F to 77°F). It cannot tolerate extreme temperature fluctuations, and care should be taken to keep it away from drafts and sudden changes in temperature.
Soil Requirements: The ideal soil for Impatiens nyungwensis is well-drained, rich in organic matter, and slightly acidic with a pH range of 5.5 to 6.5. It should be kept moist but not waterlogged. The addition of compost or peat moss to the soil can help improve its nutrient content and drainage.
Fertilizer Requirements: Impatiens nyungwensis benefits from regular fertilization with a balanced, water-soluble fertilizer. It should be applied every 2-3 weeks during the growing season. Over-fertilization can lead to excessive foliage growth at the expense of flowers.
Water Requirements: Impatiens nyungwensis requires regular watering to keep the soil moist but not waterlogged. It is important to avoid letting the soil dry out completely, as this can cause the plant to wilt and possibly die. It is best to water the plant at the base to prevent getting the foliage wet, which can lead to the development of fungal diseases.

Propagation of Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda
Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda is a beautiful tropical plant native to Central Africa. It is commonly known as the "Nyungwe Balsam." This plant is appreciated for its delicate pink flowers and its lush green foliage. Here are some of the methods used to propagate this plant:
Seeds Propagation
The most common method used to propagate Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda is seed propagation. The seeds of this plant are small and brown, and they can be harvested from mature plants. The ideal time to collect the seeds is when the seedpods turn brown, and the seeds begin to rattle inside the pod.
Once you have collected the seeds, you can sow them directly into seed trays or small pots. The soil should be moist, but not too wet, and it should be rich in nutrients. The seeds should be sown thinly and covered lightly with soil. The seeds will germinate within two weeks, and they should be kept in a warm, bright area.
Stem Cuttings Propagation
Another way to propagate Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda is using stem cuttings. This method is straightforward and effective, and it is ideal for those who want to replicate a plant that has desirable features.
To take stem cuttings, select a healthy branch from a mature plant. Cut a section of the stem that is about 10cm long, and remove the leaves from the lower 2-3cm of the stem. The cuttings should be planted in a well-draining, nutrient-rich soil mix. They should be kept in a warm, bright area and kept moist, but not too wet.
The stem cuttings should root within a few weeks, and they can be transplanted into pots or into the garden once they have established a strong root system.
Disease and Pest Management for Impatiens nyungwensis Eb.Fisch. & Dhetchuvi & Ntaganda
Impatiens nyungwensis is a beautiful and unique plant native to East Africa. However, like any other plant, it is vulnerable to diseases and pests that can cause damage and reduce its appeal. Here are the most common diseases and pests that might affect the plant and ways to manage them:
Diseases
Impatiens downy mildew is a serious disease affecting Impatiens species, including Impatiens nyungwensis. The disease is caused by a fungus-like organism called Plasmopara obducens. The symptoms include yellowing leaves, stunted growth, and a white, downy coating on the undersides of the leaves. To manage this disease, remove and discard infected plants and avoid replanting Impatiens in the same location.
Root rot is another common disease of Impatiens nyungwensis. It is caused by a fungal pathogen that thrives in moist soil and can lead to wilting, yellowing leaves, and plant death. To prevent this disease, avoid over-watering and ensure good soil drainage. Also, remove and discard infected plants.
Pests
The most common pests that affect Impatiens nyungwensis are spider mites and aphids. Spider mites are tiny arachnids that can cause significant damage to the plant by sucking sap from the leaves. The symptoms include webbing, yellowing leaves, and a speckled appearance. To manage spider mites, spray the plant with water to remove the pests and their webbing. You can also use insecticidal soap or neem oil to control them.
Aphids are small, soft-bodied insects that can also cause significant damage to the plant by sucking the sap from the leaves. The symptoms include distorted or curled leaves and a sticky residue on the leaves. To manage aphids, spray the plant with water to remove them. You can also use insecticidal soap or neem oil to control them.
Regular monitoring of Impatiens nyungwensis is essential to detect any signs of disease or pest infestation. Early intervention is critical in managing these problems to prevent further spread and damage to the plant. By following these disease and pest management practices, you can keep your Impatiens nyungwensis healthy and looking beautiful.
