Notes on Lunaria sp. (Perennial and Annual Honesty)

The Genus Lunaria is a member of the Mustard family (Brassicaceae), and includes only four species, all native to central and southern Europe. Two of which are reported to occur in the United States (USDA): Lunaria annuas (Annual Honesty), and Lunaria rediviva (Perennial Honesty). L. rediviva has been introduced to a few northeastern states in the US, while the more common L. annuas has been introduced to most of the US besides the central states.

Description of L. annuas (Wikipedia): "It is an annual or biennial growing to 90 cm (35 in) tall by 30 cm (12 in) broad, with large, coarse, pointed oval leaves with marked serrations. The leaves are hairy, the lower ones long-stalked, the upper ones stalkless.[1] In spring and summer it bears terminal racemes of white or violet flowers, followed by showy, light brown, translucent, disc-shaped[1] seedpods (silicles) the skin of which falls off to release the seeds, revealing a central membrane which is white with a silvery sheen, 3–8 cm (1–3 in) in diameter; they persist on the plant through winter.[2] These pods are much used in floral arrangements."

Hesperis matronalis (Dame's Violet), another Eurasian mustard introduced to North America, is occasionally confused with the Lunaria species.
