BACKGROUND: Black henbane is a native plant of Europe commonly found in waste areas, pastures, along rights-of-way, and fence lines. It is poisonous to both animals and humans; however, it has medical use in controlled circumstances.
DESCRIPTION: As either an annual or biennial, black henbane grows 1 to 3 feet tall. Leaves have pointed lobes and prominent veins. Off-white or greenish flowers with purple centers and veins are 1 to 2 inches wide. Pineapple-shaped fruit is borne in leaf axils. Each fruit has five lobes and contains hundreds of tiny black seeds. Bloom occurs in late spring.
CONTROL: Herbicides can be very effective when applied during rosette to bloom stages. Digging can offer some control.
