Italian Arum, also known as Italian Lords and Ladies (Arum Italicum) is a perennial forb in the Arum Family (Araceae). It’s native to Europe and Africa, blooms Apr-May and grows 1-1.5 ft. It’s a common weed in forests and savannas near house gardens; tolerates moist to dry soils and full shade to full sun exposure.
Italian Arum is a highly invasive plant that can get out of control within the gardens where it’s planted. It’s a big problem in stream and forest restoration because known aquatic herbicides only burn the growth but do not kill the roots (aquatic herbicides are used near streams; they are safer on the environment, wild life and break down faster). Italian Arum spreads by seed and bulblets, which are juvenile bulbs produced between the top of the bulb and the top soil. Gardeners should avoid planting Italian Arum and look for native alternatives. If digging to remove already established plants dispose of all material; don’t leave it as compost or yard debris.
