Echinacea, commonly known as coneflower, is a vibrant flowering plant belonging to the Asteraceae family. It closely resembles chrysanthemums with its large, colorful blooms that have a glossy appearance. This perennial plant is widely used both as a cut flower and for large-scale potting. Its flowers can grow up to 15 cm in diameter, making it an excellent choice for dried flower arrangements.
Propagation of Echinacea can be done through sowing, division, or cuttings, but sowing is the most common method. For seed propagation, sowing should take place in late spring or early autumn. After preparing the seedbed by leveling and watering, soak the seeds before sowing them in small areas of about 4 square centimeters each. Germination typically occurs within two weeks at a temperature of around 22°C. Once the seedlings have developed two true leaves, they can be transplanted. When the plants reach about 10 cm in height, they are ready to be planted in the field with a spacing of 40 cm between each plant.
Division is another effective propagation method, especially for established perennial plants. This is best done in spring or autumn, where 4–5 buds are cut from the roots and replanted. Cuttings can also be taken from shoots about 5 cm long and inserted into a sandy medium. The environment should be humid but not overly wet, and root development usually takes 3–4 weeks at 22°C.
When cultivating Echinacea, choose a sunny location with well-drained soil. Before planting, the soil should be deeply tilled and enriched with bone meal or sesame residue. Proper spacing and regular watering are essential. During the growing season, apply liquid fertilizer, and near the flowering stage, use potassium permanganate solution to maintain healthy growth and full, well-proportioned plants. After flowering, remove spent blooms and dead leaves, and provide adequate water or cover the base with compost to help the plant survive winter.
To encourage more blooms, consider staggered sowing. Sowing in the fall can lead to flowering from late April to early May, while sowing in early spring may result in blooms from July to August. Sowing in May can lead to September blooms, and June sowing can produce flowers in October. Pruning after June flowering and providing proper nutrients can help the plant bloom again in September and October.
For potted Echinacea, use loose, fertile soil or a mix of garden soil and compost. Plant 3–5 seedlings per pot. Pinch back the plants during early growth to promote branching. Annual repotting is recommended. Avoid overwatering, especially during rainy seasons when humidity is high. Apply diluted liquid fertilizer during the growing season, and water after fertilizing to prevent leaf burn. Grow plants in greenhouses or in well-ventilated, sunny areas. Maintain a minimum temperature of 10°C, and provide shade during hot summer months.
