Moonflower is a herbaceous perennial belonging to the family Ranunculaceae. Most species must be dealt with carefully as they are extremely poisonous. Their leaves are palmate or deeply lobed into 5 to 7 segments and are dark green in color. The flower stems are tall and erect with a group of blue, purple, white, yellow or pink  flowers. The upper pedal of their five pedals is in the form of a  helmet shape, hence the english name monkshood. Historically the poison derived from this plant has been used to kill wolves , thus the other well known name Wolf’s bane.
