Begonia gouroana A.Chev., also known as Gouro’s begonia, is a species of flowering plant that belongs to the Begoniaceae family. This plant is native to Central Africa, specifically in Cameroon and Nigeria. It was first described by Auguste Jean Baptiste Chevalier, a French botanist in 1949.
Appearance
Begonia gouroana is a perennial herb that grows up to 40cm in height. It has succulent stems that are green in color, with red spots on the upper part of the stem and leaves. The leaves are asymmetrical, with a heart-shaped base and pointed tip, measuring about 6-15cm in length and 4-12cm in width. The upper surface of the leaves is dark green, while the lower surface is pale green. The plant produces small, pinkish-white flowers in clusters that bloom from the axils of the leaves.
Common Names
Begonia gouroana is known by different names depending on the region. In Cameroon, it is called “Ndidu” by the Bassa people, “Mvondo” by the Beti people, and “Bina” by the Bafut people. In Nigeria, it is referred to as “Otaheite begonia” due to its resemblance to the Begonia of the South Pacific island of Tahiti.
Uses
Begonia gouroana is widely used in traditional medicine in Cameroon to treat various ailments such as diarrhea, fever, and stomach pains. The leaves of the plant are boiled and ingested orally or used as an enema. Its stem sap is also applied topically to heal wounds and skin infections. In some African cultures, the plant is believed to have spiritual healing properties and is used in rituals. Begonia gouroana is also popular as an ornamental plant and can be grown indoors or in a shaded patio.
Light Conditions
Begonia gouroana A.Chev. requires partial shade to full sunlight to thrive. It can be grown indoors near a bright window receiving indirect sunlight or in an outdoor space that offers a balance between direct sunlight and shade. Direct exposure to sunlight for prolonged periods can lead to leaf scorching and stunted growth.
Temperature Requirements
The plant prefers warm temperatures ranging between 60°F to 85°F (16°C to 29°C). It cannot survive in frosty environments and needs to be protected from extreme temperature changes. The ideal temperature range to maintain healthy growth is between 70°F to 75°F (21°C to 24°C).
Soil Requirements
Begonia gouroana A.Chev. requires well-draining soil that retains moisture. A soil pH range of 6.0 to 7.0 works best for growing the plant. It requires a fertile soil mix that is rich in organic matter, such as peat moss, compost, or organic fertilizers. The plant does not tolerate dry soil conditions and requires regular watering to maintain soil moisture levels. However, overwatering can cause root rot, so it is essential to maintain a balance in watering practices.
Cultivation of Begonia gouroana A.Chev.
Begonia gouroana A.Chev. is a plant that requires a warm and humid environment to thrive. It is highly sensitive to low temperatures and frost, so it should be grown in warmer climates or in greenhouses.
The plant can be propagated through stem cuttings and should be planted in well-draining soil mixed with peat moss or compost to provide nutrients.
It is essential to provide the plant with adequate sunlight, but not direct sunlight as it can scorch the leaves. A semi-shaded area would be more suitable for Begonia gouroana A.Chev.
Watering Needs of Begonia gouroana A.Chev.
Begonia gouroana A.Chev. needs regular watering as it cannot tolerate drought. The soil should be kept consistently moist but not waterlogged. Overwatering can lead to root rot, which can be detrimental to the plant.
The plant also benefits from misting, which helps to increase the humidity around the plant. This is especially important during hot and dry weather.
Fertilization of Begonia gouroana A.Chev.
Regular fertilization is necessary to keep Begonia gouroana A.Chev. healthy and to promote growth. A well-balanced fertilizer with equal parts nitrogen, phosphorus, and potassium can be applied every two weeks during the growing season.
It is crucial to follow the instructions on the fertilizer packaging and not to over-fertilize the plant as this can lead to chemical burn and damage the plant.
Pruning of Begonia gouroana A.Chev.
Begonia gouroana A.Chev. requires pruning to maintain its shape and improve its overall appearance. Dead, damaged, or diseased leaves and stems should be regularly removed from the plant.
The plant can also be pinched back to promote a more compact and bushy growth habit. This should be done during the growing season, and the removed parts can be used for propagation.
Pruning should be done with clean and sharp tools to prevent the transmission of diseases to the plant.
Propagation of Begonia gouroana A.Chev.
Begonia gouroana A.Chev. is a beautiful plant that can be propagated using various methods. The plant can be propagated from seeds, stem cuttings, and leaf cuttings. All these methods have their benefits and drawbacks, and the choice of the propagation method should be based on the grower's preferences and resources.
Propagation from seeds
The seeds of Begonia gouroana A.Chev. are small, and several seeds can be obtained from the mother plant. The seeds should be sown in sterile soil, misted with water, and covered with plastic to retain humidity. The seedlings should be kept in a warm and bright location and regularly misted to prevent the soil from drying out. After a few weeks, the seedlings should appear, and the plastic covering should be gradually removed to accustom the seedlings to the ambient humidity.
Propagation from stem cuttings
Stem cuttings are a common method of propagating Begonia gouroana A.Chev. For this method, a healthy stem should be selected, clipped just below a node, and its bottom end should be dipped in rooting hormone. The stem should be planted in damp soil, covered with a plastic bag, and placed in a warm and bright location. After a few weeks, roots should emerge from the stem, and the plastic bag can be gradually removed.
Propagation from leaf cuttings
Leaf cuttings are another popular method of propagating Begonia gouroana A.Chev. For this method, a healthy leaf should be taken from the mother plant, along with a small section of the stem. The stem's bottom end should be dipped in rooting hormone, and the leaf should be inserted into damp soil. The stem section should be covered with soil, and the leaf should remain above the soil level. The container should be covered with a plastic bag and placed in a warm and bright location. After a few weeks, the leaf should develop roots, and a new plant should emerge from the soil.
Disease and Pest Management for Begonia Gouroana A.Chev.
Begonia gouroana A.Chev. is a beautiful species of Begonia well-known for its unique foliage. Like any other plant, it is susceptible to pests and diseases. To ensure that your begonia grows and blooms healthily, it is crucial to take adequate measures to prevent and control diseases and pests.

Remove the affected parts of the plant, and use a fungicide or bactericide to prevent further infection.
Another common disease that can affect Begonia gouroana A.Chev. is powdery mildew. Powdery mildew is a fungal disease that appears as a white powdery substance on the leaves. You can control this disease by keeping the area around the plant dry, reducing humidity levels, and removing any affected parts of the plant as soon as possible. You can also use a fungicide to control the disease.
By following these simple measures, you can prevent and control pests and diseases that can affect your Begonia gouroana A.Chev. Keeping your plant healthy will ensure that it blooms with vibrant colors, providing a beautiful addition to your garden or home decor.
