Environmental Studies

Callapalustris (Water Arum) Araceae

Physical characteristics

The plant is very poisonous when fresh due to its high oxalic acid content, but the rhizome, like that of Caladium, Colocasia and Arum, is edible after drying, grinding, leaching and boiling.

Ecological characteristics

It is native to cool temperate regions of the Northern Hemisphere, in central, eastern and northern Europe (France and Norway eastward), northern Asia and northern North America.
