Lunaria annua, commonly known as Honesty, is a biennial plant in the family Brassicaceae. It is native to the Balkans and southwest Asia but has been widely naturalized in temperate regions. The plant is known for its distinctive, translucent seed pods that resemble silver coins, which is why it is also called 'Silver Dollar' plant. It typically grows to about 60-90 cm in height and has heart-shaped leaves and purple or white flowers.
Lunaria annua prefers moderate temperatures and indirect bright light. It thrives in environments with moderate humidity and should be watered when the soil partially dries out. The plant is relatively easy to care for and can adapt to both indoor and outdoor settings.
土壌
Lunaria annua prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is kept moderately moist but not waterlogged. Good drainage is essential to prevent root rot.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant once a month during the growing season to promote healthy growth and flowering.
植え替え
Repot Lunaria annua when it outgrows its current container, typically every 1-2 years. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the early spring before the growing season begins.
伝搬
Lunaria annua can be propagated by seeds. Sow the seeds in early spring or late summer directly into the soil. The seeds require light to germinate, so do not cover them with soil. Keep the soil moist until germination occurs.
剪定
Pruning is generally not required for Lunaria annua. However, you can remove spent flowers to encourage more blooms and prevent the plant from self-seeding excessively.
毒性
Lunaria annua is not toxic to pets or humans. It is safe to grow in gardens where children and pets are present.
追加
Lunaria annua is often grown for its ornamental seed pods, which are used in dried flower arrangements. The plant can self-seed and spread in the garden, so it may require some management to prevent it from becoming invasive.
