Origin
Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler is a plant species that originates from mainland Central Africa.
Common Names
The plant is commonly referred to as "Le Tabapoula" in French and "Namwele" in Tshiluba, a language spoken in the Congo.
Uses
The plant has been used traditionally as a poison in Central Africa for hunting. The bark of the stem and roots are folded into small balls, which are then injected into the stream or body of water where fish are located. The active ingredient, diterpene esters, paralyzes the fish, which are then easily captured. The plant has also been used to treat snake bites and other venomous animal bites.

Its leaves are simple, alternate, and elliptical in shape, measuring 12-20 cm in length and 6-8 cm in width. The plant produces small, inconspicuous flowers that are green to reddish-purple in color. The fruit is a small, greenish-yellow berry that contains one or two seeds. The plant's bark is smooth and grayish-brown in color with vertical fissures.
Growth Conditions of Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler
Classified as an evergreen shrub, Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler can grow up to a height of 1-3 meters. It is a slow-growing plant that requires specific growth conditions to thrive.
Light Requirements
D. lujae De Wild. & T.Durand var. gillardinii requires bright and indirect sunlight to grow well. It is best to place the plant near a north or east-facing window where it can receive ample light without direct exposure to the sun's intense rays. Insufficient light can cause the plant's leaves to turn yellow, while too much direct sunlight can scorch the leaves.
Temperature Range
The optimal temperature range for the growth of D. lujae De Wild. & T.Durand var. gillardinii is between 18-25°C. The plant is tolerant of different temperature ranges, but it prefers warmer conditions than cooler conditions. It is resistant to high temperatures but should be protected from frost or temperatures below 10°C, which are detrimental to its growth.
Soil Requirements
The plant requires well-draining soil that is rich in organic material. A soil mixture with equal parts of sand, peat moss, and perlite will provide the ideal growing medium for D. lujae De Wild. & T.Durand var. gillardinii. The soil's pH levels should be between 6 and 7.5, which is slightly acidic to slightly alkaline. Waterlogged soil can lead to root rot, so the plant's drainage should be excellent.
Humidity is not a significant factor for the growth of D. lujae De Wild. & T.Durand var. gillardinii as it can tolerate low humidity levels. However, misting the plant occasionally will help keep the leaves clean and increase humidity levels for better growth.
Regular fertilization with a balanced fertilizer should be done during the growing season to ensure healthy growth. The plant should be pruned regularly to shape it and remove any dead or diseased branches.
Cultivation methods
Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler, commonly known as "Dichapetalum," is native to tropical regions of Africa and requires warm temperatures to grow. The plant needs well-draining soil that is rich in organic matter. It is a sun-loving plant and requires at least 6 hours of direct sunlight each day. It can be propagated by seeds or stem cuttings. It is essential to keep the plant away from strong winds and to provide support to the stems as the plant grows.
Watering needs
Dichapetalum requires regular watering to keep the soil moist but not waterlogged. The frequency of watering will depend on environmental conditions such as temperature, humidity, and soil type. As a general rule, it is recommended to water the plant deeply and less frequently. Avoid overwatering, as it can lead to root rot.
Fertilization
Dichapetalum responds well to regular fertilization. A balanced, all-purpose fertilizer can be applied during the growing season, which is spring and summer. It is essential to follow package instructions to avoid over-fertilization, which can damage the plant. As a general rule, it is recommended to fertilize Dichapetalum every two weeks during the growing season.
Pruning
Dichapetalum requires minimal pruning. Dead, damaged, or diseased leaves and stems should be pruned off as soon as possible to prevent further damage to the plant. Pinching back the tips of the plant can encourage branching and provide a fuller appearance. It is recommended to prune Dichapetalum during the growing season, which is spring and summer.
Propagation of Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler
Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler is a relatively rare plant species, and propagating it can be quite challenging. Fortunately, a few methods have been found successful in propagating this plant.
Propagation by seeds
The most common and effective way to propagate Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler is by seeds. Seeds can be sourced from mature plants and can be sown in a suitable soil medium. The seeds are small but easily sown and germinated. It is advisable to use fresh seeds, as they have a higher success rate. The seeds should be sown in a warm and humid environment and must be kept moist at all times. Germination time is approximately 2-3 weeks, and the seedlings can be transplanted when they are large enough to handle.
Propagation by cuttings
Propagation of Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler by cuttings is also possible, but it rarely succeeds. Cuttings should be taken from mature and healthy plants, preferably during the active growing season. The cuttings should be dipped in rooting hormone powder and planted in a suitable soil medium. The cuttings should be kept in a warm environment with high humidity and must be kept moist at all times. Rooting takes time, and the success rate is low.
Propagation by division
Propagation of Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler by division is not possible since this plant does not form clumps or produce offsets.
Disease Management for Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler
Like all plants, Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler can be affected by diseases. The following are some common diseases that might affect the plant:
- Leaf spot: This is a fungal disease that causes circular spots on the leaves of the plant. To manage this disease, remove infected leaves and dispose of them properly. Avoid overhead watering to prevent the spread of the disease. If necessary, use a fungicide labeled for use on Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler.
- Root rot: This disease is caused by a fungus that attacks the roots of the plant, causing them to rot. To prevent this disease, avoid overwatering the plant and ensure that it is grown in well-draining soil. If necessary, use a fungicide labeled for use on Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler.
- Powdery mildew: This fungal disease causes a white, powdery growth on the leaves of the plant. To manage this disease, improve air circulation around the plant to reduce humidity. Remove infected leaves and dispose of them properly. If necessary, use a fungicide labeled for use on Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler.
Pest Management for Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler
While not as common as diseases, Dichapetalum lujae De Wild. & T.Durand var. gillardinii (Hauman) Breteler can also be affected by pests. The following are some common pests that might affect the plant:
- Aphids: These small, soft-bodied insects suck sap from the leaves of the plant, causing them to yellow and distort. To manage aphids, spray the plant with a strong stream of water to dislodge them. If necessary, use an insecticidal soap or neem oil to manage the infestation.
- Spider mites: These tiny pests feed on the plant, causing it to appear stippled and discolored. To manage spider mites, improve air circulation around the plant to reduce humidity. If necessary, use an insecticidal soap or neem oil to manage the infestation.
- Mealybugs: These small, white insects are covered in a waxy, cotton-like substance. They feed on the plant and can cause it to yellow and weaken. To manage mealybugs, remove them from the plant by hand or with a cotton swab soaked in rubbing alcohol. If necessary, use an insecticidal soap or neem oil to manage the infestation.
