Along the north side of their Dupont Circle station, hundreds of mysterious morning glories and other flowers have been coming up in planter boxes along the Metro's north escalators.

Metro found out who the secret flower planter was when they received a polite letter on June 3 written by the flower planter himself, Henry Docter. Henry sent a letter asking permission to continue caring for hundreds of flowers he had planted a week earlier at the Metro transit system.

"Arrests, fines, and imprisonment" for planting flowersImmediately, the Metro responded to Docter on June 11 with a "cease and desist" letter threatening "arrest, fines and imprisonment" if Docter tried to weed, water, or tend to the flowers. Concerned about public safety, Metro said that they didn't want Docter or anyone else to be injured caring for flowers that were set in steep, cobblestone inclines.
