Iochroma cyaneum, commonly known as the blue cestrum or violet churur, is a flowering shrub in the Solanaceae family. Native to the tropical regions of South America, it is known for its vibrant blue to violet tubular flowers. This plant thrives in wet tropical climates and can grow up to 3 meters in height.
Iochroma cyaneum requires bright, indirect light and thrives in moderate temperatures. It prefers high humidity and should be watered regularly to keep the soil evenly moist. This plant can be grown both indoors and outdoors, provided it is protected from direct, harsh sunlight.
土壌
The plant prefers well-draining loamy soil that retains moisture but does not become waterlogged. A soil mix that includes organic matter will help provide the necessary nutrients and drainage.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to support its growth and flowering.
植え替え
Repot Iochroma cyaneum every 1-2 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the spring.
伝搬
Propagate Iochroma cyaneum through stem cuttings. Take cuttings in the spring or early summer, dip the cut end in rooting hormone, and plant in a well-draining soil mix. Keep the cuttings in a warm, humid environment until they root.
剪定
Prune the plant regularly to maintain its shape and encourage bushier growth. Remove any dead or damaged branches and trim back leggy growth. Pruning is best done in the spring.
毒性
Iochroma cyaneum is toxic to pets and humans if ingested. All parts of the plant contain toxic alkaloids that can cause symptoms such as nausea, vomiting, and diarrhea. Handle with care and keep out of reach of children and pets.
