Arum italicum

Arum italicum is a species of flowering herbaceous perennial plant in the family Araceae, also known as Italian arum and Italian lords-and-ladies.[1]

It grows 1–1.5 feet (30–46 cm) high, with equal spread. It blooms in Spring with white flowers that turn to showy red fruit.[1] It is cultivated as an ornamental plant for traditional and woodland shade gardens.[1] Some gardeners use this arum to underplant with hosta, as they produce foliage sequentially; when the hosta withers away, the arum replaces it, leaving the ground covered.[2] Numerous cultivars have been developed for garden use, of which A. italicum subsp. italicum 'Marmoratum' has gained the Royal Horticultural Society's Award of Garden Merit.[3]

Arum italicum can be invasive in some areas.[2]

In 1778, Lamarck noticed that the inflorescence of this plant produces heat.[4]
