Lunaria (Lunaria annua)

Botanical Name: Lunaria annua
Common Names: Honesty, Money Plant, Silver Dollar Plant
Biennial | Heirloom | Edible & Ornamental

Lunaria, often called Honesty or the Silver Dollar plant, is a traditional cottage garden favorite, grown for its charming spring flowers and striking translucent seed pods that resemble silver coins. A biennial, it forms leafy rosettes in the first year and bursts into bloom in the second, producing masses of purple blossoms, followed by decorative silvery discs. Easy to grow from seed and a wonderful addition to borders, wildflower patches, or dried flower arrangements, Lunaria thrives in the Irish climate with minimal fuss.
