Allergy information

Low Allergy risk
Moderate Pollen level

Lunaria annua can cause mild allergic reactions in some people, especially those sensitive to pollen. The main trigger is its pollen, which may cause sneezing or itchy eyes during flowering. To reduce exposure, avoid handling the plant during its bloom and keep it away from indoor areas where pollen can accumulate.

Common problems

Overwatering can cause root rot, and poor drainage may lead to fungal diseases. In low light, the plant may grow leggy and produce fewer flowers.

Uses

Primarily grown as an ornamental plant for its flowers and decorative seed pods. The seed pods are popular in dried flower arrangements.

Notes

Deadhead spent flowers to encourage more blooms and prevent unwanted self-seeding if desired. The plant can be grown indoors near a sunny window but prefers outdoor conditions for best flowering.
