Rose Campion (Lychnis coronaria)
When Jefferson noted the "Lychnis bloom" at Shadwell in 1767, he was probably referring to the wooly-leaved, self-seeding Rose Campion, a biennial or short-lived perennial popular in early American gardens. It has attractive magenta or white flowers in early summer as well as ornamental, silver foliage that resembles Lamb's Ears (Stachys byzantina). Rose Campion was sold by Bernard McMahon, the Philadelphia nurseryman, in 1804.
