Arum italicum (Italian Arum) is a tuber-forming perennial in the family Araceae that has been used extensively in the horticultural industry. It is native to much of Europe, northern Africa, and western Asia and has naturalized throughout the wetter regions of the western U.S. as well as locally in the eastern U.S., in Australia, New Zealand, portions of South America, and other regions. The plant is noted for its aggressive growth habit in gardens and riparian areas, its ability to cause contact dermatitis, and for being unpalatable to toxic for livestock. It reproduces both by seed that can be carried long distances and by lateral tubers, making it very difficult to control once established.
