Common Names
The plant is commonly called African Healing Oil Plant due to the oil extracted from its seeds that has been used traditionally in Africa for its medicinal properties. It is also known as Campylo, Ikwan, and Ikhuan in different African languages.
Uses
The oil extracted from the seeds of Campylospermum hiernii is used for medicinal purposes. It is believed to have anti-inflammatory, analgesic, and antioxidant properties. The oil is traditionally used in Africa for treating arthritis, rheumatism, back pain, and other forms of pain. It is also used as a remedy for skin conditions such as eczema, psoriasis, and dry skin.
Aside from its medicinal uses, the plant is also used for ornamental purposes. Its attractive flowers make it a great addition to gardens and landscaping.
General Appearance
Campylospermum hiernii is a shrub or small tree that can grow up to 6 meters tall. It has a straight, woody stem with smooth grey or brown bark. Its leaves are simple, alternate, broadly elliptical, and dark green in color. The plant produces small, white or cream-colored flowers that are highly fragrant and arranged in clusters. Its fruits are small, round, and red when ripe, containing a single seed that is used to extract the oil.
Growth Conditions for Campylospermum hiernii
Campylospermum hiernii is a plant that is native to tropical regions of Africa, including Angola, Cameroon, and Gabon. It belongs to the family Ochnaceae and typically grows in lowland rainforests, often near rivers or streams.
Light Requirements
Campylospermum hiernii grows best in areas with diffused sunlight or partial shade. While it can tolerate some direct sunlight, prolonged exposure to intense sun can damage its leaves and reduce its overall growth. In its natural habitat, it often grows beneath the canopy of other trees or in areas with filtered sunlight.
Temperature Needs
The ideal temperature range for Campylospermum hiernii is between 20°C to 30°C (68°F to 86°F). It thrives in warm, humid environments with consistent temperatures. Temperatures below 15°C (59°F) can cause leaf damage and slow down its growth. In colder climates, it is often grown as a houseplant where it can be kept in a warm, sheltered space like a greenhouse.
Soil Requirements
Campylospermum hiernii prefers well-drained soil that is rich in organic matter. It does well in soils that are moist but not waterlogged. A pH level between 5.0 and 6.5 is ideal for its growth. In its natural environment, it grows in soils that are high in nutrients and have a higher level of acidity, often near rivers and streams where the soil is enriched by floods.
Cultivation
Campylospermum hiernii is a tropical plant that requires warm temperatures to thrive. It can be grown in both indoor and outdoor settings in a well-draining soil mix with good fertility. The plant can tolerate partial shade, but it prefers full sun exposure.
Watering Needs
Campylospermum hiernii needs regular watering, especially during the growing season. The soil should be moist, but not waterlogged, to prevent root rot. Allow the top inch of soil to dry out before watering again. During the winter, reduce watering to prevent waterlogging the soil.
Fertilization
Campylospermum hiernii benefits from regular feeding during the growing season. Use a balanced liquid fertilizer every two weeks to keep the plant looking healthy. When fertilizing, follow the manufacturer's instructions and ensure that the roots are well moistened.
Pruning
Pruning is essential to keep Campylospermum hiernii in good shape and promote new growth. The best time to prune is during the winter dormancy period. Start by removing any dead, diseased, or damaged branches. Cut back the remaining branches to the desired size and shape, ensuring that each cut is made above a healthy leaf node.
Propagation of Campylospermum hiernii (Tiegh.) Exell
Campylospermum hiernii (Tiegh.) Exell, commonly known as the African maple, is a perennial shrub that belongs to the family Ochnaceae. The plant is native to tropical West Africa and is known for its attractive foliage and showy yellow flowers. Propagation of the African maple can be done through various methods, including seed propagation, stem cuttings, and layering.
Seed Propagation
Propagation of Campylospermum hiernii can be done through seed propagation. The seeds should be collected from the plant when they are ripe and fresh. The collected seeds should be cleaned, dried, and stored in a cool and dry place. Sowing of the seeds can be done in a well-draining potting mix, and the pot should be kept in a warm and moist place. Germination of the seeds usually occurs within four to six weeks.
Stem Cuttings
Propagation of Campylospermum hiernii can also be done through stem cuttings. The ideal time to take stem cuttings is during the growing season. Cuttings should be taken from healthy and vigorous plants. The stem cuttings should be about 10-15cm long and should be taken from semi-hardwood growth. The cuttings should be treated with rooting hormone and planted in a well-draining potting mix. The pot should be kept in a warm and humid place, and the cuttings should be watered regularly. Roots usually develop within four to six weeks.
Layering
Propagation of Campylospermum hiernii can also be done through layering. This method involves bending a low-growing stem to the ground and burying a section of it in the soil. The buried section of the stem should be wounded and treated with rooting hormone. The stem should be held down by a wire or a small stake. The layered stem should be kept moist, and roots usually develop within six to eight weeks. Once roots have developed, the rooted stem can be cut from the parent plant and transplanted to a new location.
Disease and Pest Management for Campylospermum hiernii (Tiegh.) Exell
Campylospermum hiernii is a beautiful and ornamental plant, but like all plants, it is susceptible to disease and pest infestation. It is crucial to have an effective management strategy to ensure that the plant remains healthy and thrives. Here are some common diseases and pests that could affect the plant and how to manage them.
Common Diseases
1. Root Rot: Root rot is a fungal disease that affects the roots of the plant, causing them to decay and eventually die. Symptoms of root rot include yellowing of the leaves, wilting, and stunted growth. To prevent root rot, ensure that the soil is well-drained and not too soggy. Avoid overwatering the plant and use a fungicide to treat the disease.
2. Powdery Mildew: Powdery mildew is a fungal disease that affects the leaves of the plant, causing them to develop a white powdery coating. The disease can spread and cause the foliage to yellow and eventually drop. To manage powdery mildew, ensure that the plant is not overwatered and there is good air circulation around the plant. Use a fungicide to treat the disease.
3. Leaf Spot: Leaf spot is a fungal disease that affects the leaves of the plant, causing round or irregular brown or black spots. Over time, the spots may grow in size and merge. To prevent leaf spot, avoid getting the leaves wet when watering the plant and remove any infected leaves. Use a fungicide to treat the disease.
Common Pests
1. Spider Mites: Spider mites are tiny pests that usually appear on the undersides of the leaves. They cause yellowing and stippling of the leaves and can quickly spread to the entire plant. To manage spider mites, regularly wash the leaves with a gentle stream of water or a mild soap solution. Use an insecticidal spray to treat the pests.
2. Scale Insects: Scale insects are small, sap-sucking pests that appear as hard or waxy bumps on the leaves or stems of the plant. They cause wilting and yellowing of the leaves and can weaken the plant. To manage scale insects, wash the plant with a cloth or paper towel dipped in rubbing alcohol to kill the pests.
3. Mealybugs: Mealybugs are small white or gray insects that appear as cottony masses on the leaves or stems of the plant. They suck the sap from the plant and can cause yellowing of the leaves and stunted growth. To manage mealybugs, remove them with a cotton swab dipped in rubbing alcohol or use an insecticidal soap.
Regularly inspecting your Campylospermum hiernii plant for signs of disease and pests can help ensure early detection and effective management. A healthy and thriving plant will brighten up any garden or indoor space.
