Common Names
The plant is commonly known as Angola Basket Grass or Angola Coelachne.
Uses
The plant has no known practical or economic uses.
General Appearance
Coelachne angolensis (Rendle) Jacq.-Fél. has green leaves with a pointed tip and flat stems that grow up to 20 cm long and about 1,5 mm wide. It has a unique cylindrical flowering head with multiple spikes that form a basket-like structure. The flowering heads grow up to 5 cm long and 10 cm wide.
Light Requirements
Coelachne angolensis is a shade-loving plant that tolerates low levels of light. It grows well under the canopy of taller trees in forests, where it receives dappled or filtered sunlight. Direct exposure to full sunlight can scorch the leaves and damage the plant.
Temperature Requirements
The plant prefers warm to hot temperatures ranging from 20°C to 30°C. It can tolerate occasional drops to 15°C but does not grow well in temperatures below 10°C. In its natural habitat, the plant experiences warm and humid conditions, with mean monthly temperatures of 23°C to 26°C.
Soil Requirements
Coelachne angolensis prefers well-draining soils that are rich in organic matter. The soil type can range from sandy to clayey, as long as it is not compacted and allows for good root growth. It prefers neutral to slightly acidic soil with a pH range of 6.0 to 7.5. The plant does not thrive in waterlogged soils and requires moderate to high levels of moisture to grow well.
Cultivation
Coelachne angolensis (Rendle) Jacq.-Fél. can be grown indoors or outdoors, and it requires a sunny to partially shaded location. The plant thrives in well-drained soil that is slightly acidic. It can be propagated through seeds or cuttings during the growing season.
Watering
Coelachne angolensis (Rendle) Jacq.-Fél. prefers moderate watering, and the soil should be kept slightly moist during the growing season. However, avoid overwatering as it can cause root rot. During the winter months, watering should be reduced to prevent waterlogging.
Fertilization
Fertilize Coelachne angolensis (Rendle) Jacq.-Fél. with a balanced fertilizer during the growing season to encourage healthy growth. Use a slow-release fertilizer, liquid fertilizer, or a compost tea solution to feed the plant. However, avoid overfertilizing as it can lead to leaf burn and nutrient toxicity.
Pruning
Prune Coelachne angolensis (Rendle) Jacq.-Fél. during the growing season to maintain a bushy and compact shape. You can remove dead, damaged, or diseased foliage to encourage healthy growth. Also, remove any weak or crossing branches to enhance the plant's appearance.
Propagation of Coelachne angolensis
Coelachne angolensis (Rendle) Jacq.-Fél. can be propagated by both sexual and asexual methods.
Sexual propagation
The plant produces seeds that can be collected and sown to grow new plants. To propagate through seeds, ensure that the seeds are mature and dry before collecting them. Sow the seeds in well-drained soil in a container or bed. Water properly, and keep the soil moist until germination occurs. After germination, move the seedlings to a spot with good sunlight and a consistent water supply.
Asexual propagation
The plant can also be propagated asexually through division. This method involves dividing the plant clumps into individual sections and planting them separately. To do this, dig up the plant and gently separate the roots and shoots. Plant each divided section in a pot or suitable ground and water well. Ensure that the soil is kept moist, and the plants are kept in a sunny and warm spot.
Disease Management
Coelachne angolensis is susceptible to fungal infections such as leaf rust, powdery mildew, and black spot disease. To manage these diseases, it is recommended to remove infected leaves and debris and destroy them. Fungicides can also be used as a preventative measure, following instructions on the label for application and dosage. It is also crucial not to overwater the plant and keep the surrounding area free of weeds and debris that can harbor disease-causing fungi.
Pest Management
Spider mites and aphids are common pests that can infest Coelachne angolensis. Spider mites can be identified by the webbing they produce, while aphids can be seen clustering on the plant's new growth. Infested leaves can be removed and destroyed, and the plant can be treated with insecticidal soap or neem oil. Natural predators, such as ladybugs, can also be introduced to the area to help control pest populations. It is essential to monitor the plant regularly and take immediate action if pests are detected to prevent further damage.
