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. It is cultivated as an ornamental plant for traditional and woodland shade gardens. 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. 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.
In 1778, Lamarck noticed that the inflorescence of this plant produces heat.
