Cacalia yakusimensis

Growth Characteristics: Cacalia yakusimensis is a perennial herbaceous plant belonging to the Asteraceae family, native primarily to Yakushima Island in Japan. This plant typically grows to a height of 30–50 cm, with straight, thin stems. The leaves are heart-shaped, glossy, pointed at the tips, and have serrated edges. White or light purple flowers bloom between summer and autumn, and the inflorescence is in the form of a capitulum.

Propagation Method: This plant is primarily propagated by seeds. The best time for sowing is spring, and it is recommended to cold-treat the seeds at around 5°C for two weeks to increase germination rates. It can also be propagated by root division. In this case, the roots are divided and planted in spring or autumn.

Cultivation Method: It thrives in full sun or partial shade and prefers well-drained soil. Caution is required as root rot may occur in poorly drained soil. As a general rule, water should be given when the surface soil is dry, and overwatering should be avoided. Since the plant may be somewhat sensitive to cold in winter, it is recommended to provide insulation using a topsoil mulch.

Uses in the Garden:
Sedum is well-suited for shaded or natural-style gardens. Planting it along the edges of flowerbeds or in spaces under trees can create a natural atmosphere. Additionally, it is suitable for ornamental purposes as it creates a beautiful spectacle when in bloom.

Major Pests and Control Methods:

Major pests include root rot and powdery mildew. Since root rot is caused by excessive moisture, it is important to create a well-drained soil environment. Powdery mildew can occur in poorly ventilated or high-humidity environments, so it is advisable to plant at appropriate intervals rather than overcrowding. If an outbreak occurs, it is necessary to remove the infected parts, leaving healthy tissue intact. When using fungicides, adhere to the appropriate dilution concentration.

The batwing plant Iacuximensis is a relatively easy-to-care-for plant suitable for beginners and is popular in gardens due to its beautiful appearance.
