More Information About Arum
Arum are mostly European natives and relatives of the Asian cobra lily or jack-in-the-pulpit (arisaema). Although arum is not related to a real lily it is sometimes referred to as the Arum lily (it's actually an aroid). The name arum lily is also sometimes used for Zantedeschia too although that is mainly a British thing and we never do that. A similar common name, Titan Arum, is used for Amorphophallus titanum.
Arum plants are deer-resistant and quite easy to grow in a wide range of soils and moisture levels, although part sun and well-drained soils are best. Arum lily species are contrarians, as they are dormant in the summer and "wake-up" in the fall or winter, due to their native Mediterranean environment which has hot, dry, unpleasant summers and cool, moist winters.
I can think of few plants that provide such beautiful foliage in the winter garden as arum. The most popular species is the italian Arum italicum, which boasts the best leaf patterns. There are several named cultivars of Arum italicum, often in scarce supply. Arum lilies also produce a wide variety of large and colorful spathe and spadix flowers, some of which are interestingly fragrant. Arum lily flowers are followed by stalks of bright red berries after the foliage has gone dormant in late spring. Try pairing Arum with plants that will fill in during their dormant period such as hosta, hemerocallis and iris.

In the Pacific Northwest and northern California, italian Arum is considered to be an invasive species which spreads rapidly out of the garden, into the wild by seed and bulb. However, in most other places, italian arum is well behaved and not noxious.
