Arum is a genus of about 25 species of flowering plants in the family Araceae, native to Europe, northern Africa, and western Asia, with the highest species diversity in the Mediterranean region.

They are rhizomatous, herbaceous perennial plants growing to 20-60 cm tall, with sagittate (arrowhead-shaped) leaves 10-55 cm long. The flowers are produced in a spadix, surrounded by a 10-40 cm long, coloured spathe, which may be white, yellow, brown or purple; some species are scented, others not. The fruit is a cluster of bright orange or red berries.

All parts of the plants are poisonous, ^[1]containing significant amounts of calcium oxalate as raphides.
