Overview:
Clermontia caerulea Hbd. var. degeneri Skottsberg, also known as Degener's blue clermonia, is a rare and endangered plant species that belongs to the Bellflower family (Campanulaceae). The plant is named after David R. Degener, a renowned plant collector and taxonomist.
Origin:
Degener's blue clermonia is endemic to Hawaii and can typically be found on the islands of Maui, Molokai, and Lanai. It is primarily found in wet, montane forests at elevations between 1450 to 1850 meters (4750 to 6100 feet).
Common Names:
Degener's blue clermonia is also known by several other common names including:
- Maui blue clermonia
- Molokai blue clermonia
- Blue waxflower
Uses:
Degener's blue clermonia is primarily used for ornamental purposes due to its attractive blue flowers and glossy leaves. However, due to its rarity, the plant is not commonly cultivated or used for commercial purposes. In traditional Hawaiian culture, the plant may have had spiritual or medicinal properties, but this knowledge has been lost over time.
Appearance:
Degener's blue clermonia is a small to medium-sized evergreen shrub that can grow up to 3 meters (10 feet) tall. Its leaves are shiny, dark-green, and oval-shaped, and can reach up to 25 centimeters (10 inches) in length. The plant produces showy tubular flowers that are bright blue-violet in color and can grow up to 5 centimeters (2 inches) long.
Light Requirements
Clermontia caerulea Hbd. var. degeneri Skottsberg thrives in a bright but shaded environment. In its natural habitat, this plant grows under the cover of forest canopies and receives dappled or indirect sunlight. Therefore, it is recommended to place the plant near a north or east-facing window or any spot that receives bright, indirect sunlight.
Temperature Requirements
This plant prefers a temperate to a cool environment and does not tolerate extreme heat or cold. It grows best at a temperature range of 16°C to 24°C (60°F to 75°F) during the day and around 12°C to 16°C (54°F to 60°F) at night. However, this plant can survive in temperatures as low as 10°C (50°F). Therefore, it's advisable to keep the temperature stable and avoid exposing the plant to sudden temperature changes.
Soil Requirements
Clermontia caerulea Hbd. var. degeneri Skottsberg prefers well-draining soils that retain moisture. A mix that contains peat, perlite, and sand in a 3:1:1 ratio works well for this plant. The soil's pH should be slightly acidic, with a range of 5.5 to 6.0. Avoid using heavy soils or those with a high clay content that retains water as they may cause root rot. In its natural habitat, this plant grows in volcanic soil with high organic matter content, such as decomposed leaves and bark.
Cultivation Method for Clermontia caerulea Hbd. var. degeneri Skottsberg
Clermontia caerulea Hbd. var. degeneri Skottsberg is a tropical plant that requires cultivation in a warm and humid environment. It is advisable to grow it in a greenhouse, or in a room with high humidity levels. The plant requires filtered sunlight, and it is advisable to keep it in a shaded area.
When growing Clermontia caerulea Hbd. var. degeneri Skottsberg, it is important to use well-draining soil. You can add peat moss and perlite to the soil to improve drainage. The plant thrives in acidic soil, so make sure the pH range of the soil remains between 4.5 and 5.5.
Watering Needs for Clermontia caerulea Hbd. var. degeneri Skottsberg

Propagation of Clermontia caerulea Hbd. var. degeneri Skottsberg
Clermontia caerulea Hbd. var. degeneri Skottsberg, commonly known as 'Oha wai', is a rare and endangered plant species endemic to the Hawaiian Islands. Propagation of this species can be tricky, but there are a few methods that have been successful.
Seed Propagation
The most common method of propagation for Clermontia caerulea Hbd. var. degeneri Skottsberg is through seed. The seeds can be collected from mature fruits and need to be sown as soon as possible. They should be planted in a well draining potting mix and kept in a warm, humid environment. Keep the soil moist but not soaking. Germination can take anywhere from a few weeks to several months.
Stem Cuttings
Stem cuttings can be taken from healthy plants in the summer months when the plant is actively growing. Cuttings should be taken from the current season's growth and should be around 4-6 inches long. Remove the lower leaves and dip the cut end into rooting hormone before planting in a well-draining potting mix. Cover the pot with a plastic bag to create a humid environment and keep in bright, indirect light. Rooting can take up to 4-6 weeks.
Division
Clermontia caerulea Hbd. var. degeneri Skottsberg can also be propagated through division. This method is best done in the spring or fall when the plant is not actively growing. Carefully dig up the plant and divide the rootball into smaller sections, making sure each division has some roots. Replant each section in a well-draining potting mix and water thoroughly.
With patience and care, propagation of Clermontia caerulea Hbd. var. degeneri Skottsberg can be successful. Once established, these beautiful plants will add a unique touch to any garden.
Disease Management
One of the common diseases that can affect Clermontia caerulea Hbd. var. degeneri Skottsberg is powdery mildew. This fungus appears as a white, powdery coating on the leaves and stems of the plant. To manage powdery mildew, remove the affected plant parts and avoid overhead watering. You can also apply fungicides to prevent or control the spread of the disease.
Another disease that can affect the plant is leaf spot. This disease causes small, circular spots on the leaves, which may enlarge and turn brown or gray. To manage leaf spot, remove the affected leaves and avoid overhead watering. You can also apply fungicides to prevent or control the spread of the disease.
Pest Management
One of the common pests that can affect Clermontia caerulea Hbd. var. degeneri Skottsberg is the spider mite. This pest appears as tiny, red or brown insects on the leaves and stems of the plant. To manage spider mites, spray the plant with water to dislodge the pests or apply insecticidal soap or oil to kill them.
Another pest that can affect the plant is the mealybug. This pest appears as small, white, cotton-like insects on the leaves and stems of the plant. To manage mealybugs, remove the affected plant parts and apply insecticidal soap or oil to kill the pests. You can also introduce natural predators, such as ladybugs or lacewings, to control the population of mealybugs.
