It is mostly evergreen, but in some areas, it may lose its leaves in winter.
Common Names
The plant is commonly known as the African tea, apiesdoring, umsenge, umsisi, or White ebony. The name African tea comes from the fact that the leaves of this plant are used to make tea in some African countries.
Uses
Canthium affine has many medicinal properties. In traditional African medicine, the roots, bark, and leaves of this plant are used to treat various ailments such as malaria, fever, dysentery, and diarrhea. The leaves are also used as an infusion to treat coughs and colds. In some countries, it is commonly used as a herbal tea.
Canthium affine is also an important plant for wildlife. The leaves, fruits, and bark provide food for various animals such as monkeys, birds, and antelopes. The plant also attracts insects such as butterflies, bees, and moths.
General Appearance
Canthium affine has a round, spreading crown and shiny, dark green leaves that are elliptic in shape. The leaves have smooth margins and a pointed tip. The plant produces small, white or cream-colored flowers that are pleasantly fragrant. The flowers are followed by small, round, purplish-black fruits that attract birds and other animals. The bark is dark gray or brown and is smooth with shallow fissures, which form irregular patches as the tree ages.
In summary, Canthium affine is a small tree or shrub that is native to southern and eastern Africa. It is commonly known as African tea and has medicinal uses such as treating malaria, fever, and diarrhea. The plant produces shiny, dark green leaves, small, fragrant flowers, and small, purplish-black fruits. It is also an important plant for wildlife and attracts various animals and insects.
Light Requirements
The Canthium affine plant prefers a relatively shady area of the garden or indoors. Direct sunlight can damage the leaves of the plant, so it should be placed in an area with diffused light or partial shade. It is suitable for growing in indoor spaces with good natural light sources, but it can also be grown in areas with artificial light sources.
Temperature Needs
The Canthium affine plant enjoys a moderate temperature range that is usually found in most households or outdoors. Optimal temperature ranges for the plant should be between 60 and 80°F (15 and 27°C). Temperatures below 55°F (13°C) may lead to health issues, and the plant may stop growing or die. On the other hand, temperatures above 90°F (32°C) may damage the plant and cause scorching of leaves and foliage. Therefore, maintaining a comfortable temperature range is the key to healthy plant growth and maintenance.
Soil Quality and Moisture Requirements
The Canthium affine plant prefers soil that is well-draining and offers enough nutrients for its growth. The plant can grow in standard potting soil or garden soil with amendments made available. It is essential to maintain the appropriate soil moisture levels, because extremely dry or wet soil can lead to stress, yellowing of leaves, and increased susceptibility to pests and diseases. Ensure the soil remains slightly moist all the time and make sure to never overwater the plant or allow the soil to dry entirely.
Cultivation methods
Canthium affine is a woody shrub that grows up to 4 meters high and 2 meters wide. It thrives in tropical climates and requires well-draining soil to grow properly. To cultivate Canthium affine, ensure that you plant it in an area with plenty of sunlight, preferably in a spot that receives morning sun and afternoon shade. Plant the shrub in a hole twice as wide and deep as the root ball, then backfill with soil. Tamp the soil down to get rid of any air pockets and water the plant well until it is established.
Watering needs
Water the Canthium affine moderately, as over-watering may cause root rot. The plant requires ample moisture in the growing season, especially during the summer months. Water the shrub deeply and infrequently, making sure that the soil is thoroughly moistened. Avoid wetting the foliage when watering, as this may cause fungal diseases.
Fertilization
Fertilize Canthium affine in the spring and summer using a balanced fertilizer to promote proper growth. Feed the shrub once every two months. Be careful not to over-fertilize as it may cause burns on the leaves and harm the plant.
Pruning
Pruning Canthium affine is essential to keep the shrub in shape and encourage bushy growth. Prune branches that are dead, diseased, or damaged at any time of the year to prevent the spread of diseases. During the growing season, remove any weak or crossing branches. If the shrub is outgrowing its space, trim it back after flowering to control its size. Always use sharp pruning shears when cutting back Canthium affine to prevent any injury to the plant.
Propagation of Canthium affine (Robyns) Hepper
Canthium affine (Robyns) Hepper, also known as forest coffee, is a species of plant that belongs to the Rubiaceae family. This plant can be propagated using various methods, including:
Seed propagation
One common propagation method for Canthium affine is by seed. The seeds should be collected from mature fruits, which are usually yellow or red when ripe. After collection, the seeds should be cleaned and soaked in clean water overnight. The soaked seeds can then be sown in a mixture of sand and peat or soil. The seeds should be covered with a thin layer of the soil mixture, and the soil should be kept moist until germination, which usually takes about 2-3 weeks.
Cuttings
Canthium affine can also be propagated using cuttings. Hardwood cuttings can be taken from the plant during the dormant season. The cuttings should be about 20-30 cm long and should be treated with rooting hormone. The cuttings can then be planted in a well-draining soil mix and kept in a warm, humid environment until they start rooting, which can take about 2-3 months.
Division
Division is another propagation method for Canthium affine. This method is best suited for plants that have grown large enough to have multiple stems or crowns. The plant should be carefully dug up, and the stems or crowns should be separated using a sharp, sterilized knife. Each division should have a healthy root system, and the cuttings should be planted in a well-draining soil mix. The soil should be kept moist until the plant establishes.
With proper care, Canthium affine can be propagated easily using the methods described above. It is important to note that each propagation method has different requirements and conditions that must be met to ensure successful propagation.
Disease Management
Canthium affine (Robyns) Hepper is relatively resilient to diseases; however, it can succumb to a few infections. Some of the common illnesses that might affect this plant include:
- Leaf Spot: This is a fungal disease that causes discolored spots on the leaves of the plant. The spots may vary in size and color, depending on the severity of the infection. To manage this disease, remove the infected leaves, and spray the plant with a fungicide.
- Anthracnose: This is another fungal disease that causes yellow or brown spots on the leaves, stems, and fruits of the plant. To manage this disease, remove the infected parts of the plant, and dispose of them. You can also treat the plant with a fungicide.
- Root Rot: This is a disease caused by a fungus that attacks the roots of the plant, causing them to rot. The infected plant usually has wilted leaves, and it may eventually die. To manage this disease, remove the infected plant and avoid overwatering your Canthium affine (Robyns) Hepper.
Pest Management
Canthium affine (Robyns) Hepper is also relatively resistant to pests; however, it might occasionally be attacked by:
- Mealybugs: These are tiny, soft-bodied insects that suck the sap from the plant, causing it to weaken and wilt. To manage this pest, remove the bugs manually using a cotton swab dipped in alcohol. You can also use insecticides.
- Spider mites: These are tiny arachnids that feed on the leaves of the plant, causing them to curl up and turn yellow. To manage this pest, spray the plant with water to dislodge the mites. You can also use insecticidal soap or neem oil.
- Caterpillars: These are the larvae of a variety of moths and butterflies that feed on the leaves of the plant, causing them to have holes. To manage this pest, remove the caterpillars manually, and dispose of them. You can also use insecticides.
