Common Names
This plant is commonly known as "Yellow Stapelia" or "Yellow Carrion Flower".
Uses
Although not commonly used for medicinal purposes, some traditional African healers use the plant to treat stomach ailments and skin infections. The plant is commonly grown as an ornamental plant and is also used in landscaping as a border plant.
General Appearance
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach is a low-growing succulent plant that can grow up to 10-15cm in height. The plant has thick, fleshy, green stems that grow horizontally and produce clusters of small yellow flowers. The flowers are star-shaped and have a very strong, unpleasant odor similar to that of rotting flesh. The plant requires full sunlight and well-draining soil and is hardy to drought and heat.
Light Requirements
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach prefers bright, indirect sunlight. Direct sunlight may harm the succulent's leaves, so it is best to place it in a location where it can receive bright light without being exposed to direct sunlight.
Temperature Requirements
The optimal temperature range for Stapelia praetermissa L.C.Leach var. luteola L.C.Leach is between 60-75°F (15-24°C). It can be grown outdoors in warmer climates but should be grown indoors in colder climates during the winter months.
Soil Requirements
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach requires a well-draining soil mixture that is specifically formulated for succulents. A cactus mix or a mixture of coarse sand, perlite, and peat moss can be used in place of a commercial succulent mix.
Cultivation Methods
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach is a succulent plant that is relatively easy to grow. The plant thrives in bright, indirect sunlight and well-draining soil. Therefore, consider planting the plant in a pot with drainage holes, with cactus potting mix. Also, the plant requires warm temperatures, between 70°F to 85°F (21°C to 29°C).
Watering Needs
Unlike most succulent plants, Stapelia praetermissa L.C.Leach var. luteola L.C.Leach has higher watering needs. Water the plant thoroughly when the top 2 inches of the soil is dry. However, avoid letting the plant sit in water, as it can cause root rot. During the winter, reduce watering since the plant is dormant.
Fertilization
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach requires fertilization during the growing season. Hence, apply a balanced fertilizer (20-20-20) diluted to half strength, every two weeks during the growing season. However, avoid fertilizing during the winter, as it may cause the plant to grow weak and leggy.
Pruning
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach does not require regular pruning. However, you can prune the plant to control its size and shape. Also, remove old, yellow leaves and stems to prevent the spread of disease. Use sharp, sterile shears to avoid damaging the plant near the wound.
Propagation of Stapelia praetermissa L.C.Leach var. luteola L.C.Leach
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach, or commonly known as the carrion plant, is a succulent plant that is native to South Africa. It produces star-shaped flowers that emit a foul odor, resembling that of rotting flesh, hence the name carrion. Propagating this plant can be done through various methods.
Seed Propagation
Propagating Stapelia praetermissa var. luteola through seeds is relatively easy. The first step is to collect the mature dried seed pods from the parent plant. Then, sow the seeds in well-draining, sandy soil, and water the seeds sparingly. It is best to keep the soil moist but not wet. The seeds should germinate after two to four weeks. Once there are established roots, transplant the seedlings into individual pots and provide them with bright, indirect light.
Stem Cuttings Propagation
Stem cuttings propagation is another effective way to propagate Stapelia praetermissa var. luteola. To propagate through this method, use a sharp, sterilized knife to cut off a healthy stem from the parent plant. Leave the stem to dry for a few days before planting in well-draining soil mix. Water the plant sparingly, keeping the soil slightly moist but not waterlogged. After a few weeks, the cutting should start to produce new roots and leaves.
Division Propagation
Division propagation is a method of separating a mature plant into several smaller plants. To propagate Stapelia praetermissa var. luteola through division, gently remove the plant from its pot and carefully separate the root ball in half or quarters, using a sterilized knife. Make sure each division has its roots and stem. Plant each segment in a well-draining soil mix and water sparingly. Provide bright, indirect light and keep the soil slightly moist but not waterlogged. The separated segments should take root and begin to grow within a few weeks.
Disease Management
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach is generally resistant to diseases. However, it may be vulnerable to fungal infections such as powdery mildew, which can occur in humid conditions or due to poor air circulation. It can also be affected by bacterial soft rot, especially when it is overwatered.
The most effective way to manage powdery mildew is to prevent it from occurring. It can be achieved by ensuring proper air circulation, avoiding crowding plants, and keeping humidity levels low. Using a fungicide is another option, but it is not recommended for use on edible plants.
Bacterial soft rot can be prevented by avoiding overwatering and ensuring that there is adequate drainage. If it is already present, the affected parts should be removed and destroyed, and the plant should be relocated to a dry location. A copper-based fungicide can also be used to manage bacterial soft rot.
Pest Management
Stapelia praetermissa L.C.Leach var. luteola L.C.Leach is susceptible to mealybugs, spider mites, and scale insects. These pests can cause significant damage to the plant and, if left untreated, can lead to the plant's death.
Mealybugs and scale insects can be managed by handpicking or wiping them off with a soft cloth. Insecticidal soap or neem oil can also be used as a control method.
Spider mites can be managed by spraying the plant with water to increase humidity levels. Predatory insects such as ladybugs and lacewings can also be introduced as a natural control method. Insecticidal soap can also be used against spider mites.
Regular inspection and monitoring of the plant are important to catch any pest infestations early and prevent them from spreading. Quarantining new plants before introducing them to the growing area is also a good practice.
