The exotic looking arums are in the family Araceae, all of which have an unusual flowering arrangement. Small flowers, are on a club-like spadix, male above, female below, surrounded by a large hood-like often highly coloured spathe. It may even change from year to year, with all the flowers being male or femle! Normally you won't see the flowers, as the spathe completely hides the them and much of the spadix. If pollinated, by flies, the spathe will eventually shrivel, revealing a spike of often coloured berries. The leaves are often arrowhead-shaped (sagittate), patterned, or coloured and very attractive.
