Overview:
Stapelianthus choananthus (Lavranos & A.V.Hall) R.A.Dyer is a succulent plant from the family Apocynaceae. It is a perennial succulent with a unique shape and beautiful flowers. This plant is native to the Cape Province of South Africa.Common names:
This plant is commonly known as the "Carrion Flower" or "Olive Stapeliad".Appearance:
Stapelianthus choananthus is a low-growing perennial succulent that typically grows up to 10cm long and 10cm wide. It has olive-green to brownish-green stems with four-angled or almost square-shaped ribs. It also has small, warty tubercles that can grow up to 1 mm long. These tubercles help give the plant its unique, bumpy texture. The flowers of Stapelianthus choananthus are quite striking. They grow on the end of long, slender stalks that can reach up to 5cm in length. The flowers are usually yellow in color with brown or reddish-brown markings. They are star-shaped, with five pointed petals that are deeply grooved at the base.Uses:
Stapelianthus choananthus is grown mostly for ornamental purposes. Its unique shape and interesting textures make it a popular choice for succulent collectors and enthusiasts. It is also a popular plant for xeriscaping, which is a type of gardening that focuses on using drought-resistant plants that require minimal water. In traditional medicine, this plant is not commonly used. However, some African cultures use the plant to treat various conditions such as blurred vision, fever, and constipation. The plant is also sometimes used as a food source for humans and animals in its native Africa. Overall, Stapelianthus choananthus is a fascinating and attractive succulent that is easy to grow and care for. It is a perfect plant for those who appreciate unique plant shapes and textures, and for those who need low-maintenance plants.Light requirements
Stapelianthus choananthus requires bright but indirect sunlight to grow properly. Direct sunlight can burn the leaves and cause irreversible damage to the plant. It is recommended to place the plant near a window that receives morning sunlight or use a sheer curtain to filter the light. A lack of adequate light can result in elongated stems and sparse flower production.
Temperature requirements
The ideal temperature range for Stapelianthus choananthus is between 60-80°F (15-27°C). It is important to avoid extreme temperatures as the plant cannot tolerate frost or prolonged exposure to temperatures above 90°F (32°C). During the winter months, it is recommended to keep the plant in a cooler location to encourage the formation of flower buds.
Soil requirements
Stapelianthus choananthus thrives in well-draining soil that is rich in organic matter. A combination of peat moss, perlite, and sand is ideal for this succulent. The soil should be kept slightly moist during the growing season, but it is important to avoid over-watering as this can lead to root rot. It is recommended to allow the soil to dry out slightly between waterings.
Cultivation
Stapelianthus choananthus is a succulent plant that requires excellent drainage. It is recommended to plant it in a sandy, well-draining soil mix composed of coarse sand, perlite, and potting soil. The ideal location for this plant is a sunny area with partial shade, as it requires plenty of light and good air circulation. It should be planted in a pot with good drainage holes and not overcrowded with other plants.
Watering Needs
Stapelianthus choananthus is tolerant of drought conditions, making it an excellent choice for succulent enthusiasts who tend to forget to water their plants. Watering should be done sparingly, and the soil should be allowed to dry out before the next watering. Overwatering can cause root rot and eventual death of the plant. During the winter months, when the plant is dormant, watering should be reduced even further.
Fertilization
Fertilization is essential for healthy growth in Stapelianthus choananthus, but it should be done sparingly. It is recommended to fertilize during the growing season from early spring to late summer. The fertilizer used should be low-nitrogen, high-phosphorus, and potassium-rich. It should be diluted to half the recommended strength and applied every four weeks. Over-fertilization can lead to soft, weak growth and an increased susceptibility to pests and diseases.
Pruning
Pruning is not typically necessary for Stapelianthus choananthus, as it grows relatively slowly. However, dead or damaged growth can be removed with a pair of sterilized pruning shears. If the plant outgrows its pot, it can be transplanted to a larger container in the spring. Additionally, any offshoots that grow from the plant's base can be propagated by carefully cutting and transplanting them into their own pots.
Propagation of Stapelianthus choananthus
Stapelianthus choananthus can be propagated through various methods including:
Stem Cuttings
The most common method of propagating Stapelianthus choananthus is through stem cuttings. Take a cutting of about 10 cm in length from the top of a healthy stem, making sure that it has at least two pairs of leaves. Allow the cutting to dry for a few days, then plant the cutting in a well-draining, sandy mix. Water sparingly and keep the cutting in a warm, bright location. The cutting should root within a few weeks.
Leaf Cuttings
It is also possible to propagate Stapelianthus choananthus through leaf cuttings. Take a healthy leaf and cut it in half lengthwise. Allow the cuttings to dry for several days. Plant the cuttings in a well-draining, sandy mix, and water sparingly. Within a few weeks, new roots should form from the base of the leaf.
Division
Stapelianthus choananthus can also be propagated through division. As the plants mature, they tend to clump together, and these clumps can be divided into smaller, individual plants. Gently lift the plant from its container and tease apart the roots. Replant the smaller plants in separate containers, making sure they are planted at the same soil level as the parent plant.
Offsets
Stapelianthus choananthus occasionally produces offsets, or "pups," which can be separated from the parent plant and grown on their own. Once the offsets have developed their own root system, they can be planted in soil using the same method as stem cuttings.
Disease Management
The Stapelianthus choananthus is generally a hardy plant that doesn't fall prey to diseases easily. However, under unfavorable conditions such as excessive humidity and lack of proper airflow, fungal infections may affect the plant. Leaf spots, powdery mildew, and stem rots are the common fungal diseases that can infect the Stapelianthus choananthus.
To manage fungal diseases, it is advisable to provide proper air circulation around the plant. Ensure that the soil is kept dry and avoid overhead watering. If a fungal infection is detected, pruning the affected parts and applying a fungicide can also help to control the disease.
Pest Management
The Stapelianthus choananthus is susceptible to insect infestations, especially mealybugs, spider mites, and scale insects. These pests feed on the plant sap, causing the leaves to curl and yellow, and eventually leading to stunted growth.
To manage insect infestations on the Stapelianthus choananthus, it is important to detect the pest early. Regularly inspect the plant for signs of infestation such as webbing, sticky residue, and curled leaves. Use insecticidal soap or neem oil to control the pests. Alternatively, dabbing rubbing alcohol on the pests can also help to eliminate them.
In summary, keeping the Stapelianthus choananthus in a favorable growing environment, monitoring it regularly, providing good air circulation, and maintaining proper hydration are crucial for disease and pest management.
