A genus of low to medium growing tuberous perennial plants. Of the 25 or so species generally recognised, only a handfull are grown for their showy spathe or glossy, arrow-shaped leaves. If left alone in the garden some species will form quite large clumps and seedlings and end up being a nuisance. One that fits this category is A. italicum. Really pretty patterned appearance on its leaves and ok if you have a large area to cover but not good in suburbia. The common Arum lily often highlighted by those that dislike arums is not actually an Arum. It actual name is Zantedeschia aethiopica. And yes once established is very difficult to get rid of.
Most arums are fairly tolerant of different soils types, although they do best in soils that includes a high component of organic matter. In Tassie we can grow them in full sun; however, in hotter regions part shade is best.
A. pictum is the only autumn flowering member of this genus. It also has a characteristic purple edge to the young leaves. It grows in Corsica, Sardinia and the Balearics in rocky places.
