General Description

Grown primarily for its lush, often elegantly marked leaves, this tuberous herbaceous perennial is native to southern and western Europe. The large arrowhead-shaped leaves – which in many cultivated forms such as 'Marmoratum' are heavily veined with cream or silver – emerge from the ground in fall or early winter and persist through spring. Minute flowers are borne on a yellow club-like protuberance ("spadix") in late spring, which is hooded by a greenish-yellow leaf-like bract ("spathe"). Knobby clusters of showy red berries are displayed on the naked spadix in late summer and fall.

This woodland plant requires partial shade and humus-rich, moderately moist soil. Plant its tubers in late summer at a depth two to three times their height. It combines beautifully with Japanese painted fern and many other shade-loving plants. It is listed as invasive in New Zealand, Argentina, and Oregon.
