Lunaria, common name honesty, is a genus of flowering plants in the family Brassicaceae, native to central and southern Europe and North America. It includes four species, the annual or biennial L. annua (syn. L. biennis), Lunaria elongata, the perennial L. rediviva and the rare Balkan species Lunaria telekiana.
The Latin name Lunaria means "moon-like" and refers to the plants' decorative seedpods.
They have hairy toothed leaves and terminal racemes of white or violet flowers in Spring and Summer, followed by prominent, translucent, disc-shaped seedpods, which are frequently seen in flower arrangements.
