Description

This genus is a group of around 32 herbaceous tubular flowering plants that are native to Europe, Africa and Asia. They can vary in size from 1-2 feet tall. The genus name comes from the Greek word ‘aron’, meaning ‘climbing’ or ‘poisonous plant’

Flowers consist of a spathe that surrounds the spadix and is followed by clusters of round berries in reds and oranges. Many are used as ground cover in shady areas. In some of the Pacific west of the USA, some varieties have escaped gardens and become invasive. The leaves of several species are variegated and showy. They will wait to appear in the fall and grow during the winter in warmer winter areas. Flowers will appear in spring before the plant goes dormant.

Arum lilies prefer well-drained moist soil in part sun to part shade but tolerate a wide range of soils. They are easy to grow and deer-resistant. Grow as a ground cover for a winter garden along a woodland area.
