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.

There are few plants that provide such beautiful foliage and bold texture in the winter garden as arum. The most popular species is the Italian arum (Arum italicum), which have the most interesting and unique leaf patterns. Although there are several named cultivars of Arum italicum, these popular winter woodland plants are often in short supply.

Are Arum Plants Deer Resistant?

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.

When are Arum Dormant?

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.

Which Companion Plants Go With Arum?

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.

Is Arum an Invasive Species?

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