The Sky Lily (Lilium tsingtauense Gilg) differs from ordinary lilies in that its flowers face upward. Its bright orange petals with black spots make it visually striking. The petals have a glossy surface, making it an ideal focal plant in a garden amidst lush greenery.
Sky Lilies bloom in the summer months of July and August, with each individual bearing 1 to 5 flowers. Although many varieties of lilies are sold, this native plant is one of the few that can compete with cultivated varieties.
Planting is done by placing some scales (part of the bulb) that have fully grown in the spring. The planting site should have partial shade and well-drained soil since water retention in the soil can lead to root rot. Fertilization is required in phases to support bulb growth.
To prevent growth inhibition due to excessive soil temperature in the summer, it is effective to plant ground cover plants alongside. Ground covers such as clover or grass help regulate the soil temperature and prevent moisture evaporation.
Lim Yeon-jin, the Director of the Forest Biological Resources Utilization Center, stated, “Although the Sky Lily is a native plant, it is perfectly suited as a garden plant. The best time for planting to enjoy the blooms is in May.” He added, “We hope that the garden plants recommended by the National Arboretum will enrich the lives of the public.”
