Colchicum autumnale, commonly known as autumn crocus or meadow saffron, is a tuberous geophyte native to Europe. It belongs to the family Colchicaceae and the genus Colchicum. This plant is known for its beautiful, crocus-like flowers that bloom in the fall. It prefers temperate climates and has a dormancy period during the summer.
Colchicum autumnale requires indirect bright light and moderate temperatures. It thrives in environments with moderate humidity. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. This plant can be grown both indoors and outdoors, making it versatile for different settings.
土壌
The plant prefers well-draining loam soil. Ensure the soil mix is rich in organic matter to provide moderate nutrient concentration. Good drainage is essential to prevent waterlogging, which can lead to root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant during its growing season, typically in the spring and early summer, to support healthy growth and flowering.
植え替え
Repot Colchicum autumnale every 2-3 years or when the tubers outgrow their container. Repotting is best done in the late summer or early fall before the plant begins its active growth phase. Use fresh, well-draining soil and a slightly larger pot.
伝搬
Propagate Colchicum autumnale by dividing the tubers during the dormancy period in the summer. Carefully separate the tubers and plant them in individual pots or directly in the garden. Ensure they are planted at the correct depth and water sparingly until new growth appears.
剪定
Pruning is not required for Colchicum autumnale. However, you can remove spent flowers and yellowing leaves to maintain the plant's appearance and health.
毒性
Colchicum autumnale is highly toxic to both pets and humans. All parts of the plant contain colchicine, which can cause severe gastrointestinal distress, organ failure, and even death if ingested. Handle the plant with care and keep it out of reach of children and pets.
