Overview
Stapelia flavicomata Haw. is a species of plant in the family Apocynaceae. It is native to southern Africa, particularly Namibia and Botswana, where it grows in dry, rocky areas.
Common Names
Stapelia flavicomata Haw. is commonly known as the yellow starfish flower or the spider flower due to its unique appearance.
Uses
The plant is often cultivated as an ornamental plant due to its distinctive star-shaped flowers that resemble a spider. It is usually grown in pots or containers as it prefers well-draining soil and plenty of sunlight. The flowers of the plant have a strong odor that resembles that of decaying flesh, which attracts flies and other pollinators. In traditional medicine, the plant has been used for various purposes such as treating stomach problems, fever, and snake bites. However, its medicinal properties are still being researched to determine their effectiveness.
General Appearance
Stapelia flavicomata Haw. is a succulent plant with fleshy stems that can reach up to 30 cm in length. It has many branches that are up to 2 cm in diameter and are green when young, turning to a purplish-brown color as they age. The leaves are small and inconspicuous, and fall off early in the plant's life. The flowers are up to 10 cm in diameter and have a star-shaped appearance that is yellowish-brown in color with reddish-brown spots around the center. The petals are numerous and are arranged in a circular pattern around the center. The flowers bloom in the summer season, and the plant requires well-draining soil and plenty of sunlight to grow properly.
Light Requirements
Stapelia flavicomata Haw. requires bright, indirect light for at least 6 hours a day. Direct exposure to the sun may cause leaf burn and prevent growth. It is best grown in an east or west-facing window that does not have direct exposure to the sun. Failing to provide enough light can result in slow growth or no growth at all.
Temperature Requirements
The temperature requirement for Stapelia flavicomata Haw. is slightly different during the vegetative and flowering stages. During the vegetative stage, it requires a temperature range of 20-30°C for steady growth. However, during the flowering stage, a higher temperature of 35-40°C is required for the buds to develop and flowers to bloom. Ensure that the plant is protected from frost as a sudden drop in temperature can cause flower buds to drop.
Soil Requirements
Stapelia flavicomata Haw. requires well-draining soil with the perfect pH level of 6.5-7.5. The soil should contain at least 50% organic matter to help improve soil aeration and drainage. A mixture of potting soil, sand, and perlite is ideal for growing this plant. Avoid using heavy clay as it can retain water and cause root rot. Water the plant only when the soil is dry to avoid waterlogging.
Cultivation Methods
Stapelia flavicomata Haw. is a succulent plant that prefers warm temperatures, bright light, and well-draining soil. It can grow up to 30 cm in height and 15 cm in width and can be propagated from seeds or cuttings.
The plant is best grown in a container with drainage holes to prevent standing water, which can cause root rot. Use a commercial cactus or succulent soil mix to plant the Stapelia flavicomata Haw. and water thoroughly after planting to help the roots establish.
Stapelia flavicomata Haw. can be grown indoors or outdoors, but it requires at least six hours of direct sunlight per day to thrive. If the plant is grown indoors, it should be placed near a sunny window or under a grow light. Regularly rotate the plant to ensure even sun exposure on all sides.
Watering Needs
Stapelia flavicomata Haw. is drought-tolerant and can store water in its thick stems and leaves. It is essential to allow the soil to dry completely between watering to prevent overwatering, which can cause root rot. Overwatering can be fatal to the plant, so it is better to err on the side of underwatering.
During the growing season (spring and summer), water the plant thoroughly once a week or when the soil has completely dried out. Reduce watering during the dormant season (fall and winter) to prevent cold damage and storage of energy reserves.
Fertilization
Stapelia flavicomata Haw. does not require frequent fertilization, but a slow-release cactus or succulent fertilizer can be added to the soil once every six months during the growing season. Avoid fertilizing during the dormant season.
Overfertilization can lead to leggy or spindly growth, so it is essential to follow the instructions on the fertilizer package and use a diluted concentration for succulent plants.
Pruning
Stapelia flavicomata Haw. does not require regular pruning, but removing any damaged or dead stems or leaves can improve the plant's appearance. Prune the plant during the growing season using sterilized pruning shears, taking care not to damage the healthy stems.
If the plant is becoming too large for its container, it can be repotted into a larger container with fresh soil during the growing season. Allow the plant to acclimate to the new pot for several days before watering to prevent root shock.
Propagation of Stapelia flavicomata Haw.
Propagating Stapelia flavicomata Haw. can be a fun and rewarding experience for any gardener. Here are some methods to propagate this beautiful plant:
Stem Cuttings
The most common way to propagate Stapelia flavicomata Haw. is through stem cuttings. Take a stem cutting that is at least a few inches long and remove the lower leaves. Place the stem cutting in well-draining soil and keep it in a warm spot with indirect light. Mist the cutting lightly every few days to keep it moist and watch for new growth.
Seed Propagation
Another way to propagate Stapelia flavicomata Haw. is through seeds. Harvest the seeds from the mature plant pod and place them on top of well-draining soil. Keep the soil moist and warm, and the seeds will germinate within a few weeks. Propagation through seeds may be time-consuming, but it is an excellent way to introduce genetic diversity into your collection.
Grafting
Grafting is a more advanced method of propagation that requires experience and skill. It involves attaching a cutting or a small plant onto the rootstock of another plant, creating a hybrid plant. Grafting is a way to propagate a desirable plant without losing the specific characteristics of the parent plant. However, it can be complicated and time-consuming. If you decide to attempt grafting, make sure to research and follow the necessary steps carefully.
Propagation can be a great way to grow your collection of Stapelia flavicomata Haw. plants. Whether you use stem cuttings or seeds, or take a more advanced approach like grafting, the important thing is to enjoy the process and watch your new plants thrive.
Disease and Pest Management for Stapelia flavicomata Haw.
Stapelia flavicomata Haw., commonly known as the yellow starfish flower, is known for its unique, star-shaped flowers and its ability to thrive in hot, dry conditions.
