Description
Leucanthemum is a genus of herbaceous flowering plants in the family Asteraceae, commonly known as daisies. Here are some horticultural notes on the genus:
Soil: Leucanthemums prefer well-drained soil with a neutral to slightly alkaline pH. They can tolerate a range of soil types, including sandy, loamy, and clay soils.
Light: Leucanthemums prefer full sun to part shade. They will tolerate some shade, but may produce fewer flowers.
Water: Leucanthemums require moderate watering, especially during hot and dry weather. Overwatering can lead to root rot, so be sure to provide good drainage.
Fertilizer: Leucanthemums benefit from regular fertilization with a balanced fertilizer. Avoid over-fertilizing, which can lead to weak growth and fewer flowers.
Pruning: Leucanthemums benefit from regular deadheading, which promotes the production of new flowers. They can be cut back hard in early spring to promote bushier growth.
Propagation: Leucanthemums can be propagated by division in spring or fall. They can also be grown from seed, which should be sown in early spring.
Pests and diseases: Leucanthemums are generally resistant to pests and diseases. However, they can be susceptible to powdery mildew in humid conditions. To prevent powdery mildew, provide good air circulation and avoid overhead watering.
Uses: Leucanthemums are commonly grown for their showy, daisy-like flowers, which are often used in cut flower arrangements. They make excellent border plants and can be used in mass plantings or mixed borders. Some popular cultivars include ‘Becky’, ‘Snowcap’, and ‘Alaska’.
