Cyanea kuhihewa Lammers is a rare and endangered species of flowering plant belonging to the family Campanulaceae. Commonly known as kuhihewa, it is endemic to the island of Oahu in Hawaii, where it grows in moist montane forests and subalpine shrublands.
General Appearance of Cyanea kuhihewa Lammers
The plant is a shrub or small tree, growing up to 15 feet in height with a trunk covered in persistent leaf bases. The leaves are oblong to lance-shaped, about 6-16 inches long and 1-2.5 inches wide, and arranged in an alternate pattern on the stem. The inflorescence is a large terminal cluster of yellowish-green flowers, each about an inch long, and they bloom from August to February. The fruits are capsule-like, about 0.5 inches long, with many small seeds.
Uses of Cyanea kuhihewa Lammers
There are no known medicinal uses for this plant. However, the plant plays an important ecological role in providing habitat for native birds and insects, and it also helps with watershed conservation.
The plant is highly endangered due to habitat loss, invasive species, and climate change. Conservation efforts are underway to save the remaining populations, which are found only in a few locations in the Ko'olau Mountains. The plant is protected by the Endangered Species Act and is listed as critically endangered by the International Union for Conservation of Nature.

Light Requirements
Cyanea kuhihewa Lammers requires moderate to bright indirect light. It is recommended to place the plant near a window that receives filtered or indirect sunlight. Direct sunlight can burn the leaves, so it is better to avoid exposing the plant to it.
Temperature Requirements
The ideal temperature range for Cyanea kuhihewa Lammers is between 60°F to 70°F. It can tolerate temperatures higher than this, but it is sensitive to extreme temperature fluctuations. It is recommended to keep the plant away from drafty areas and air conditioning units.
Soil Requirements
Cyanea kuhihewa Lammers prefers well-draining soil that is rich in organic matter. A recommended soil mix can be made by mixing two parts peat moss, two parts perlite, and one part potting soil. It is important to keep the soil moist but not waterlogged, as this can cause root rot. The plant also benefits from occasional fertilization with a balanced plant food.
Cultivation Methods
Cyanea kuhihewa Lammers, also known as "Hawaiian lobelioid" is a species of plant that is native to Hawaii. They thrive in high altitudes, typically from 3200 to 500 meters above sea level. They grow best in areas with moderate temperature, well-draining soil, and high humidity. When planting, make sure that the soil is rich in organic matter and is slightly acidic.
During the planting process, ensure that you choose an area that is semi-shady, as this will protect the plants from direct sunlight. Ideal plant spacing is about three feet apart, giving them enough room to grow. When planting, remove the plant gently from the container and plant it in the soil at the same level as it was in the pot.
Watering Needs
Cyanea kuhihewa Lammers requires consistent watering, preferably twice a week. Ensure that you do not overwater the plants as it can cause root rot. Watering should be reduced during the winter season to avoid causing waterlogged soil, which can also lead to root rot and death of the plant. A good soil moisture meter can be of great assistance in determining when the plant needs watering.
Fertilization
Fertilization should be done sparingly, about twice a year, in early spring and late summer. Use a slow-release organic fertilizer with a balanced NPK ratio to ensure that the plants receive the necessary nutrients for growth. During the growing season, you can supplement the soil with compost. It is essential to avoid using chemical fertilizers as they can damage and even kill these plants.
Pruning
Pruning Cyanea kuhihewa Lammers is not common as they are not fast-growing plants. However, removing any dead, damaged, or yellowing leaves can help encourage new growth and prevent any diseases. Additionally, pruning can help keep the plant's size in check and prevent them from becoming too big and overwhelming.
Propagation of Cyanea kuhihewa Lammers
Cyanea kuhihewa Lammers, commonly known as Kuhihewa cyanea, is a Hawaiian plant species belonging to the family Campanulaceae. This species is endemic to the island of Oahu, Hawaii, and is mainly propagated through seeds, cuttings, and tissue culture.
Propagation through seeds
Propagating Cyanea kuhihewa from seeds is a simple and effective propagation method. Collect mature seeds from the parent plant, which are usually black and round. Sow the seeds in a moist potting mix and cover lightly with soil, then keep them in a warm and bright area with consistent moisture levels. The seeds will germinate in two to four weeks, and once they have developed enough, transplant them into individual pots.
Propagation through cuttings
Cyanea kuhihewa can also be propagated from stem cuttings. Take a stem cutting with at least two nodes and remove the lower leaves. Dip the cut end of the stem in rooting hormone and plant it in a pot filled with moist soil. Keep the cutting in a warm and bright area, and mist it regularly to maintain moisture levels. The cutting will develop roots in four to six weeks and can then be transplanted into individual pots.
Propagation through tissue culture
Tissue culture is a propagation method that involves taking a small piece of plant tissue and growing it in a laboratory under controlled conditions. Tissue culture is a useful method for propagating Cyanea kuhihewa as this species is endangered and difficult to propagate through other methods. The process involves taking a small piece of plant tissue, sterilizing it, and placing it in a culture medium with the necessary nutrients and hormones. After a few weeks, the tissue will grow into a plantlet that can be transferred into soil and grown to maturity.
Disease and Pest Management for Cyanea kuhihewa Lammers Plant
Cyanea kuhihewa Lammers, commonly known as the Haha plant, is a rare and endangered species native to Hawaii. To keep this plant thriving, it is important to manage and prevent diseases as well as pest infestations.
Common Diseases
One of the most common diseases that can affect the Cyanea kuhihewa Lammers plant is bacterial leaf spot. This disease causes small water-soaked spots on the leaves which can quickly spread and cause the leaves to turn yellow and eventually die. To manage this disease, it is important to remove affected leaves as soon as possible and to apply a copper-based fungicide to prevent further spread.
Another common disease that can affect the Cyanea kuhihewa Lammers plant is root rot. Root rot is caused by overwatering, and symptoms include yellowing leaves, stunted growth, and wilting. To manage root rot, it is important to ensure that the plant is not overwatered and to remove affected roots if possible. It is also helpful to apply a fungicide to the soil to prevent further spread.
Common Pests
The Cyanea kuhihewa Lammers plant can be susceptible to aphids, scale insects, and mealybugs. These pests feed on the sap of the plant and can cause the leaves to curl, turn yellow, and eventually die. To manage these pests, it is important to regularly inspect the plant for any signs of infestation and to apply an insecticidal soap or neem oil to affected areas.
Spider mites are another common pest that can affect the Cyanea kuhihewa Lammers plant. These pests feed on the underside of leaves, causing them to appear speckled and eventually lead to leaf drop. To manage spider mites, it is important to regularly mist the leaves with water to increase humidity and to apply a miticide to affected areas.
Preventive Measures
Prevention is key to managing diseases and pests in the Cyanea kuhihewa Lammers plant. It is important to maintain proper watering practices, ensuring that the plant is not over or underwatered. Additionally, providing proper ventilation and avoiding placing the plant in areas with high humidity can prevent the development of fungal diseases. Regularly inspecting the plant for any signs of disease or pest infestation can also help prevent further spread.
By following these disease and pest management tips, the Cyanea kuhihewa Lammers plant can thrive and continue to contribute to the unique ecosystem of Hawaii.
