Origin
Sabicea fulva Wernham var. fulva is a plant species that is native to the Afrotropical region, particularly in the countries of Tanzania, Kenya, Uganda, and Rwanda. It belongs to the family of Rubiaceae, which is among the largest families of flowering plants, with around 13,000 species worldwide.
Common Names
This plant has several common names including African Spikenard, Wild Coffee, and Sabicea. The name African Spikenard is derived from the plant's nard-like fragrance while Sabicea is the genus name of the plant, named after the British botanist Joseph Sabine.
Uses
Traditionally, the roots of Sabicea fulva Wernham var. fulva are used to treat various ailments such as malaria, fever, and abdominal pains. Its leaves and stem bark are also used to make a decoction that is believed to help alleviate menstrual pains and diarrhea. Moreover, it is also commonly used as a natural insect repellent and is even smoked to repel insects such as mosquitoes.
General Appearance
Sabicea fulva Wernham var. fulva is a herbaceous plant that can grow up to 1.5 meters in height. It has an upright growing habit and produces green leaves that are oblong or lance-shaped. The plant produces small white flowers that are arranged in clusters and have a sweet fragrance similar to nard. Its roots are small and fibrous and it produces black fruits that are approximately 5mm in diameter.
Light Requirements
The Sabicea fulva Wernham var. fulva, also known as the yellowwood, requires partial to full shade for optimal growth. This plant thrives in the understory of the forest where it receives filtered sunlight. If grown in direct sunlight, its foliage will burn, stunting the plant's growth. In indoor settings, this plant should be placed near a well-lit window or under fluorescent lights to replicate its natural habitat.
Temperature Conditions
The yellowwood plant prefers warm and humid environments, with an ideal temperature range between 68 to 86 degrees Fahrenheit. It can tolerate slightly cooler temperatures, but prolonged exposure to temperatures below 55 degrees Fahrenheit can cause leaves to drop. During winter, it is advised to keep the plant away from cold windows or drafts to prevent temperature shock.
Soil Requirements
This plant requires fertile, well-draining, and slightly acidic soil with a pH range of 5.5 to 6.5. The ideal soil mix should have equal parts of peat moss, perlite, and vermiculite. The Sabicea fulva Wernham var. fulva plant is prone to root rot, so it is essential to avoid waterlogged soil. When watering, ensure that the soil is slightly moist but not overly saturated. Fertilize the plant during spring and summer using a balanced liquid fertilizer once a month.
Cultivation
Sabicea fulva Wernham var. fulva prefers well-draining soils with organic matter. It does best in full or partial sunlight but can tolerate some shade. The plant is cold intolerant and can't handle frost. Therefore, planting should be done when the temperature is above 15 degrees Celsius.
Watering needs
The plant has moderate watering needs. It is susceptible to root rot; thus, water should be provided only when the top inch of soil is dry. Avoid overwatering or allowing water to stagnate around the roots.
Fertilization
Sabicea fulva Wernham var. fulva is not a heavy feeder, but it does benefit from light fertilization. A balanced, slow-release fertilizer should be used during the growing season, about once every 2-3 months.
Pruning
Pruning should be done after flowering. One can remove any dead or diseased branches, or branches that are crossing and rubbing against each other. Pinching the tips of new growth can help create bushier plants. Thinning out of older branches might be necessary to improve air circulation and encourage new growth.
Propagation of Sabicea fulva Wernham var. fulva
Sabicea fulva Wernham var. fulva is a tropical plant species that belongs to the family Rubiaceae. It is known for its attractive, red-orange flowers and glossy green foliage. Propagation of this plant can be done through various methods, which are discussed below:
Seed propagation
Sabicea fulva Wernham var. fulva can be propagated from seeds. The seeds need to be collected from fully ripe and healthy fruits. Once collected, the seeds need to be cleaned and dried in a shaded and ventilated area. After drying, they can be stored in an airtight container until sowing time. The seeds should be sown in well-drained soil and covered with a thin layer of soil. Keep the soil moist and place the container in a warm and humid place. The seeds should germinate within 2-3 weeks.
Cuttings propagation
Another way to propagate Sabicea fulva Wernham var. fulva is through stem cuttings. Take a stem cutting of about 6 inches in length from a healthy and mature plant. Remove the lower leaves from the cutting and dip the cut end in rooting hormone. Plant the cutting in a well-drained soil mix and keep the soil moist. Place the container in a warm and humid place and avoid direct sunlight. The cutting should start rooting within 3-4 weeks.
Division propagation
Sabicea fulva Wernham var. fulva can also be propagated through division. This method is best done during the spring season when the plant is actively growing. Gently dig up the plant and separate the root ball into smaller sections. Each section should have a good amount of roots and foliage. Replant the sections in a well-drained soil mix and water thoroughly.
By using these propagation methods, you can easily propagate Sabicea fulva Wernham var. fulva and enjoy its beauty in your garden or home.
Disease and pest management for Sabicea fulva Wernham var. fulva
Sabicea fulva Wernham var. fulva, also known as the climbing hempvine, is a hardy and resilient plant that is native to several parts of the world. However, like most plants, it is vulnerable to a number of diseases and pests. Here are some common diseases and pests that might affect the plant and ways to manage them:
Diseases
Powdery mildew: Powdery mildew is a fungal disease that commonly affects Sabicea fulva Wernham var. fulva. It presents as a white or gray powdery coating on the leaves and stems of the plant and can cause stunted growth and reduced yield. To manage powdery mildew, it is important to keep the plant well-watered and to avoid over-fertilization. Fungicides can also be used as a preventative measure or to treat an outbreak.
Anthracnose: Anthracnose is a fungal disease that can cause severe damage to Sabicea fulva Wernham var. fulva if left unchecked. Symptoms include brown or black spots on leaves, stems, and fruits. To manage anthracnose, it is important to remove infected plant material and dispose of it properly. Fungicides can also be used as a preventative measure or to treat an outbreak.
Pests
Spider mites: Spider mites are a common pest that can cause significant damage to Sabicea fulva Wernham var. fulva. They can cause yellowing and stippling of leaves and can cause the plant to become stunted. To manage spider mites, it is important to regularly inspect the plant and remove any infested leaves or stems as soon as possible. Insecticidal soaps and oils can also be used as a preventative measure or to treat an infestation.
Caterpillars: Caterpillars can also be a problem for Sabicea fulva Wernham var. fulva. They can feed on the leaves and cause significant damage to the plant. To manage caterpillars, it is important to regularly inspect the plant and remove any infested leaves or stems. Bt (Bacillus thuringiensis) can also be used as a natural and effective treatment for caterpillar infestations.
By being vigilant and proactive in managing diseases and pests, Sabicea fulva Wernham var. fulva can thrive and produce a bountiful harvest.
