Growing Arum italicum (Italian Arum)

Pronunciation: air'-um

Italian Arum is a tuberous perennial grown for its spectacular foliage and bright red berries. Glossy, arrow-shaped leaves appear in fall and persist through winter, withering in mid-spring. Greenish-ivory flowers resembling Jack-in-the-Pulpit appear in midsummer, followed by stunning orange-red berries that may last until foliage returns in fall. In some areas, plants self-sow vigorously—choose a location where this won't be a concern. All parts are very poisonous; do not plant near vegetables or where children play.

Light/Watering

Foliage is best in light shade; red berries are most spectacular with more sun. Thrives in moist woodland conditions. Water during dry spells, then reduce watering when leaves begin to wither.

Fertilizer/Soil and pH

Grow in soil rich in organic matter with slightly acid to neutral pH (6.5–7.0). A balanced fertilizer may be applied monthly during active growth.

Pests/Diseases

Seldom has disease or pest problems; foliage is resistant to slugs and deer.

Companions

Other evergreen plants such as Bergenia, Hellebore, and Heuchera make fine companions. Italian Arum is also a perfect succession plant to follow Hosta.

Dividing/Transplanting

Divide clumps of tubers in summer when plants are dormant.

End-of-Season Care

Withering leaves may be removed in late spring, but deadheading flowers will prevent berry production.
