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.
