Enchanter’s Nightshade (Circaea lutetiana)
A woodland plant with inconspicuous two-petaled flowers whose odd shape deserves a closer look, perhaps with a glass. This plant grew in a small, shady clearing in the woods in Mount Lebanon, where it was blooming in the middle of June.
Enchanter’s Nightshade has a longstanding reputation as a sorcerer’s plant, and indeed it may have been brought from Europe for that purpose. Modern magic-supply houses often sell the seeds.
Gray describes the genus and the species:
