The plant is commonly referred to by its local names such as "Kakeya" in Nigeria and "Opongbo" in Cameroon.
Appearance
Clerodendrum euryphyllum Mildbr. is a small to medium-sized shrub that can grow up to 2.5 meters tall. The plant has hairy stems and green leaves that are oval or lance-shaped and can grow up to 10 cm long. The flowers of the plant are red, tubular, and grow in clusters at the tips of the branches. The plant typically blooms from April to June.
Uses
The leaves of Clerodendrum euryphyllum Mildbr. are used in traditional medicine in Cameroon to treat various ailments such as fever and malaria. The plant contains bioactive compounds that have been shown to exhibit antimicrobial and antioxidant properties. Additionally, the plant is used as a source of firewood and fencing material.
Due to its ornamental value, Clerodendrum euryphyllum Mildbr. is also cultivated in gardens and parks as an attractive hedge or accent plant. It is suitable for planting in shaded areas and can attract birds and butterflies.
Light Requirements
Clerodendrum euryphyllum Mildbr. thrives in bright, indirect sunlight. It is essential to protect the plant from direct sunlight as it can scorch the leaves. A shaded area with dappled light is ideal for this plant. Inadequate light can cause leggy stem growth and fewer flowers.
Temperature Requirements
Clerodendrum euryphyllum Mildbr. prefers warm temperatures between 18°C to 30°C (65°F-85°F). In colder temperatures, the plant can suffer from leaf drop and stunted growth, especially below 10°C (50°F). Moreover, the plant cannot tolerate frost, so it's essential to keep it in a warm area during the winter months.
Soil Requirements
The plant grows best in well-draining, slightly acidic soil with a pH level between 5.5 to 6.5. It prefers loamy, porous soil containing organic matter with good drainage. Soil that is too heavy or too wet can lead to root rot and other fungal diseases. It's recommended to use a potting mix made up of peat moss, perlite, and vermiculite to achieve the optimal soil conditions.
Cultivation Methods
Clerodendrum euryphyllum, also known as the Ivory Coast clerodendrum, is a tropical plant that thrives in well-draining soil and under full sun or partial shade. If you want to cultivate this plant, you should start with a healthy plant from a reputable supplier. You can propagate it through stem cuttings or seeds, although stem cuttings are more common and easier. Ensure that the soil has a pH level of 6 to 7.5 and is rich in organic matter. Plant it in a container or directly in the ground.
Watering Needs
Clerodendrum euryphyllum requires moderate watering to thrive. You should ensure that the soil is moist, but not too wet. Overwatering can cause root rot, reduced growth, and ultimately, death of the plant. You should water it once or twice per week during the growing season and reduce watering during the dormant season. Additionally, you should avoid watering the foliage, but rather the soil only.
Fertilization
The Ivory Coast clerodendrum requires regular fertilization for healthy growth and development. You should use a balanced fertilizer with an NPK ratio of 10:10:10 or 12:12:12. Apply it once a month during the growing season, that is from spring to summer. You can follow the instructions on the fertilizer label or consult with a horticulturist to determine the appropriate amount to apply. It is also advisable to incorporate organic matter such as compost or manure to enhance soil fertility and nourish the plant.
Pruning
Clerodendrum euryphyllum requires regular pruning to maintain its shape and size. You should remove any damaged, diseased, or dead branches as soon as possible to prevent the spread of diseases and pests. Additionally, you should prune back the plant after the flowering season to promote new growth and additional flowering in the following season. You can use pruning shears or a sharp knife to make the cuts and avoid tearing or damaging the plant's tissue.
Propagation of Clerodendrum euryphyllum Mildbr.
Clerodendrum euryphyllum Mildbr. can be propagated through several methods, including seed propagation, stem cutting, and layering. Each method has its own set of benefits and drawbacks, so it's important to choose the one that best suits your needs.
Seed Propagation
Propagation by seed is the most common method used for Clerodendrum euryphyllum Mildbr. The best time to sow is during the spring, and the seeds can be sown directly into the soil or started indoors. If sown directly, the soil should be moist, rich, and well-draining, and the seeds should be planted at a depth of 1 cm. When starting the seeds indoors, they should be planted in trays filled with a soil mix that drains well. The trays should be placed in a warm and well-lit area until the seedlings emerge.
Stem Cutting
Another method for propagating Clerodendrum euryphyllum Mildbr. is through stem cuttings. This method is suitable for plants that have already grown to a desirable size. Cuttings should be taken during the spring or summer and should be around 10 cm in length. They should be taken from healthy branches that are not flowering. After the leaves are removed from the bottom of the stem, the cutting is dipped into rooting hormone and placed into a well-draining soil mixture. Keep the soil moist and place the cutting in a warm and well-lit area. The cutting should develop roots in about 4 to 6 weeks.
Layering
For Clerodendrum euryphyllum Mildbr., layering is a method in which a stem is partially buried in the soil to encourage root development while it is still attached to the parent plant. The stem should be bent towards the ground and buried in a shallow trench. The top of the stem should be exposed, with only the bottom half of the stem covering the soil. After a few weeks, roots will start to develop, and once they have developed, the stem can be cut from the parent plant and transplanted elsewhere.
