Common Names

Bulbophyllum gabunense Schltr. is commonly referred to as the Gabonese Bulbophyllum or the African Tassel Orchid.

Uses

Although there are no known medicinal uses for the plant, it is primarily grown as an ornamental plant in gardens, greenhouses, and as a houseplant. It is a particularly striking orchid that is admired for its unusual and intricate flowers.

General Appearance

Bulbophyllum gabunense Schltr. is an epiphytic orchid with a creeping rhizome and pseudobulbs that grow up to 3 cm in size. The pseudobulbs have a solitary leaf that grows to around 15 cm long. The inflorescence can grow up to 45 cm in length and carries several small flowers that are borne in short clusters. The flowers are usually yellowish-green with purple marks and have a striking tassel-like appearance.

Light requirements:

Bulbophyllum gabunense Schltr. requires bright light, but it should be protected from direct sunlight as it can damage the leaves. Partial shade or filtered light is ideal for this plant. It is best to avoid keeping the plant in a completely shaded area as it will lead to weak and spindly growth.

Temperature requirements:

The optimal temperature range for Bulbophyllum gabunense Schltr. is between 18°C to 28°C. It is important to note that this plant is susceptible to sudden temperature changes, so it should be kept in a stable environment. Avoid placing the plant in areas with extreme temperature fluctuations, such as near air conditioning vents or heating systems.

Soil requirements:

Bulbophyllum gabunense Schltr. requires well-draining soil. It is best to use a mix of potting soil and perlite, which will allow excess water to drain away from the roots. The plant prefers a slightly acidic soil with a pH range of 5.5 to 6.5. Make sure to avoid using soil mixes that contain high levels of nutrients as this can lead to over-fertilization and damage the plant.

Cultivation

Bulbophyllum gabunense Schltr. is an epiphytic plant that grows well in tropical and subtropical climates. The plant requires high humidity levels and a well-draining growing medium. It's essential to choose a potting mix that contains coarse materials such as perlite, bark, or charcoal to ensure good drainage.

Growers can recreate the plant's natural epiphytic habitat by mounting the plant on a tree, using a wire basket or a piece of wood. The plant can also be grown in a pot with good drainage. It's essential to ensure the pot has drainage holes to prevent waterlogging the roots.

Watering Needs

Bulbophyllum gabunense Schltr. prefers regular watering but does not tolerate standing water. The frequency of watering will vary based on the potting medium and environmental conditions.

Growers must allow the plant to dry out slightly between watering, especially in colder months when growth slows, as overwatering can cause root rot. Watering more frequently is necessary during the warmer months and during the growing season.

Fertilization

Bulbophyllum gabunense Schltr. requires regular fertilization during the growing season. A balanced fertilizer such as 20-20-20 is suitable for this plant.

Growers should fertilize the plant every two weeks during the growing season and reduce the frequency during the dormant period. Overfertilizing the plant can cause the roots to burn and damage the plant.

Pruning

Bulbophyllum gabunense Schltr. may require pruning to remove dead leaves and pseudobulbs. Dead leaves and pseudobulbs can harbor pests and diseases, leading to further damage to the plant and other plants in the vicinity.

Growers should use sterilized tools to prune the plant to prevent the spread of disease. It's also essential to remove any damaged or diseased roots during repotting to ensure the plant remains healthy.

Propagation of Bulbophyllum gabunense Schltr.

Bulbophyllum gabunense Schltr. is a beautiful epiphytic orchid native to Central Africa. It is a popular species among orchid enthusiasts because of its striking flowers and ease of propagation.

Propagation Methods

The two common methods of propagating Bulbophyllum gabunense Schltr. are:

1. Division: Bulbophyllum gabunense Schltr. can be propagated by division during the repotting process. This is usually done when the plant outgrows its container or when the pseudobulbs start to divide.
2. Keiki: Bulbophyllum gabunense Schltr. is known to produce keikis or baby plants from the base of the pseudobulb. These keikis can be separated from the parent plant and potted in a new container.

Division

During the repotting process, carefully remove the plant from its container and gently separate the pseudobulbs. Each pseudobulb should have its own set of roots and leaves. Use a clean, sharp knife to cut through the rhizome if necessary.

Pot the new divisions in a fresh potting mix, making sure the pseudobulbs are planted at the same depth as before. Water the new divisions thoroughly and place them in a shaded area for a week or two to allow them to acclimate to their new environment before moving them to their regular spot.

Keiki

Keikis are baby plants that grow from the base of the pseudobulb. To propagate Bulbophyllum gabunense Schltr. using keikis, follow these steps:

1. Identify a healthy keiki growing from the base of the pseudobulb.
2. Use a clean, sharp knife to cut the keiki away from the parent plant, making sure it has its own set of roots and leaves.
3. Pot the keiki in a new container using a fresh potting mix. The container should be small enough to support the keiki but large enough to allow room for growth.
4. Water the new plant thoroughly and place it in a shaded area for a week or two to allow it to acclimate to its new environment before moving it to its regular spot.

Propagating Bulbophyllum gabunense Schltr. is a fun and rewarding process that can help you expand your orchid collection. With the right tools and techniques, you can successfully propagate this beautiful plant and enjoy its exotic blooms for years to come.
