Seeding: Cornus wilsoniana, commonly known as Ghost Dogwood or Wilson's Dogwood, is propagated from seeds. Collect seeds from mature fruits and remove any flesh or pulp. Stratify the seeds by placing them in a moist paper towel in a plastic bag and refrigerating them for 90-120 days to mimic winter conditions. After stratification, sow the seeds in well-draining soil or seed trays, covering them lightly with soil. Keep the soil consistently moist until germination, which typically occurs within 30-90 days under optimal conditions.
Planting: Once seedlings have developed several sets of true leaves and are strong enough for transplanting, they can be planted outdoors. Cornus wilsoniana thrives in moist, well-drained soil and prefers partial shade to full sun exposure. Planting should be done with spacing of about 10-15 feet between trees to allow for optimal growth and canopy development. Regular watering, especially during the establishment phase, is essential for promoting healthy root development and overall growth.
Landscaping and Greening: Cornus wilsoniana is highly valued for its ornamental beauty and is commonly used in landscaping and greening projects. The tree's graceful branching pattern, attractive foliage, and showy white flowers in spring make it a standout specimen in parks, gardens, and urban green spaces. It can also be used as a focal point in mixed borders or as a screen or hedge to provide privacy and habitat for wildlife.
Oil Extraction: While Cornus wilsoniana is primarily valued for its ornamental qualities, it also has potential for oil extraction. The seeds of Ghost Dogwood contain oil-rich kernels that can be extracted to produce lightwood oil, also known as tung oil. Tung oil is a drying oil that is valued for its water-resistant and durable properties. It is commonly used as a wood finish, particularly for outdoor furniture, decks, and boats. Additionally, tung oil is utilized in the manufacture of paints, varnishes, and coatings.
In summary, Cornus wilsoniana, or Ghost Dogwood/Wilson's Dogwood, offers both aesthetic and practical benefits. Its cultivation and utilization contribute to the beauty of landscapes while also providing a potential source of oil for various industrial applications, particularly in woodworking and coatings.
