Origin
Labordia hedyosmifolia Baill. var. skottsbergii Sherff, also known as N?n? ‘o K?‘ala or K?‘ala Range labordia, is a rare and endangered Hawaiian plant species that is endemic to the island of O‘ahu. It was first discovered in 1914 near Wai‘anae and named after Henri Ernest Baillon, a French botanist. The species is mostly found in mesic and wet forests at elevations of 1,300-3,000 feet on the slopes of the Ko‘olau Mountains.
Common Names
Labordia hedyosmifolia Baill. var. skottsbergii Sherff is commonly known as N?n? ‘o K?‘ala or K?‘ala Range labordia in Hawaiian. It is also sometimes referred to as Skottsberg's labordia, named after the Swedish botanist Carl Skottsberg who collected specimens of the plant in 1922.
Uses
Labordia hedyosmifolia Baill. var. skottsbergii Sherff is an important plant species in Hawaiian culture and ecology. The plant has traditionally been used by Hawaiians for medicinal purposes, including as a treatment for headaches and fever. It is also an important food source for native birds and insects, and is a key species in the restoration of degraded forests on O‘ahu.
General Appearance

Temperature Requirements
Labordia hedyosmifolia Baill. var. skottsbergii Sherff thrives in warm temperatures ranging from 18°C to 27°C. It cannot tolerate frost or prolonged cold temperatures. In colder regions, it can be grown indoors or in greenhouses to provide optimal temperature range.
Soil Requirements
The plant requires well-draining soil rich in nutrients. It grows well in a pH range of 5.6 to 6.5. The soil must be kept moist but not waterlogged. Adding organic matter to the soil enhances the growth and development of the plant.
Cultivation of Labordia hedyosmifolia Baill. var. skottsbergii Sherff
Labordia hedyosmifolia Baill. var. skottsbergii Sherff, commonly known as Hawaiian labordia or k?wa?u, is a perennial plant native to Hawaii. It is a member of the bellflower family and is prized for its striking yellow flowers. To cultivate this plant, follow the steps outlined below.
- Choose the right location: Hawaiian labordia prefers full sun to partial shade. Plant it in well-draining soil with a pH of 5.5 to 6.5. The soil should be rich in organic matter.
- Planting: Hawaiian labordia can be propagated from stem cuttings or seeds. If planting from seeds, sow them in a small pot and keep them in a warm, humid location until they germinate. Transplant the seedlings into larger pots once they are big enough to handle. If using stem cuttings, take them from healthy plants and root them in a rooting hormone before planting them in soil.
- Watering: Hawaiian labordia prefers moderate watering. Keep the soil moist but not waterlogged. Water it deeply once a week or more during dry spells.
- Fertilization: Apply a balanced fertilizer, such as 10-10-10, to the soil once every two weeks during the growing season. Be careful not to over-fertilize, as this can cause the plant to produce too much foliage and fewer flowers.
- Pruning: Prune Hawaiian labordia during the fall or winter to remove any dead or damaged growth. Cut back the plant by 1/3 to promote healthy growth and to encourage the plant to produce more flowers.
By following these cultivation and care guidelines, you can help your Hawaiian labordia thrive and produce beautiful yellow flowers year after year.
Propagation of Labordia hedyosmifolia Baill. var. skottsbergii Sherff
Propagation of Labordia hedyosmifolia Baill. var. skottsbergii Sherff is done primarily through seeds and stem cuttings.
Propagation by Seeds
Seeds of Labordia hedyosmifolia Baill. var. skottsbergii Sherff are generally collected from ripe capsules that have turned brown. The seeds must be cleaned and sown immediately for the best results. It is recommended to use a well-draining soil mix for sowing the seeds. The seeds should be covered lightly with soil and kept moist until germination occurs. Germination usually takes around 1-3 months, and the seedlings can be transplanted after they have grown their first true leaves.
Propagation by Stem Cuttings
Propagation by stem cuttings can be done at any time of the year, but it is best to take cuttings during the active growth period of the plant. Cuttings around 3-4 inches long, taken from the tip or middle of a stem, can be used for propagation. The cuttings should be dipped in rooting hormone powder and planted in a well-draining soil mix. The cuttings should be kept moist and warm until they root, which usually takes around 4-6 weeks. Once rooted, the cuttings can be transplanted to their final location.
Disease and Pest Management for Labordia Hedyosmifolia Baill. var. Skottsbergii Sherff
Labordia Hedyosmifolia Baill. var. Skottsbergii Sherff is a beautiful and delicate plant commonly found in Hawaii. However, like all other plants, it is prone to pest infestations and diseases. It is important to take proper care of the plant and manage the pests and diseases to ensure healthy growth and long life. Below are some of the common pests and diseases that might affect the plant and ways to manage them.
Pests
Aphids: Aphids are small and soft-bodied insects that suck the sap from the plant, causing yellowing, curling, and stunted growth of leaves. They also excrete honeydew, which attracts other pests and diseases. To manage aphids, use a strong jet of water to wash off the insects from the plant. You can also spray an insecticidal soap or neem oil to eliminate them.
Mealybugs: Mealybugs are small, soft, cotton-like insects that cluster on the undersides of leaves and stems. They suck the sap from the plant, causing wilting and yellowing of leaves. To manage mealybugs, use a cotton swab dipped in rubbing alcohol to wipe off the insects from the plant. You can also spray with insecticidal soap or neem oil.
Scale Insects: Scale insects are small, round, and flat insects that attach to the leaves and stems of the plant. They suck the sap from the plant, causing yellowing, curling, and stunted growth of leaves. They also secrete honeydew, which attracts other pests and diseases. To manage scale insects, use a cotton swab dipped in rubbing alcohol to wipe off the insects from the plant. You can also spray with insecticidal soap or neem oil.
Diseases
Fungal Leaf Spots: Fungal leaf spots are small, circular, dark spots that appear on the leaves of the plant. They are caused by fungi and can spread rapidly, causing defoliation and stunted growth of the plant. To manage fungal leaf spots, remove the infected leaves and spray with a copper-based fungicide.
Root Rot: Root rot is a common disease that affects the roots of the plant. It is caused by fungi that thrive in wet soil conditions, and can cause the plant to wilt, become yellow, and eventually die. To manage root rot, try to avoid overwatering the plant and ensure proper drainage. Remove the infected plant from the soil and discard it. You can also apply a fungicide to the soil to prevent further infection.
In conclusion, proper pest and disease management is essential for the healthy growth and long life of Labordia Hedyosmifolia Baill. var. Skottsbergii Sherff. Regular monitoring and timely action can help prevent serious damage to the plant and save it from irreversible harm.
