'''''Calla''''' ('''Bog Arum''', '''Marsh Calla''') is a genus of [[flowering plant]] in the family [[Araceae]], containing the single species '''''Calla palustris'''''. 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]] ([[Alaska]], [[Canada]], northeastern contiguous [[United States]]).

It is a [[rhizome|rhizomatous]] [[herbaceous]] [[perennial plant]] growing in [[bog]]s and [[pond]]s. The [[leaf|leaves]] are rounded to heart-shaped, 6–12 cm long on a 10–20 cm petiole, and 4–12 cm broad. The greenish-yellow [[inflorescence]] is produced on a [[spadix]] about 4–6 cm long, enclosed in a white [[spathe]]. The [[fruit]] is a cluster of red [[berry|berries]], each berry containing several [[seed]]s.
The plant is very [[poison]]ous 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.<ref>A Dictionary of Flowering Plants and Ferns - JC Willis</ref>
The genus formerly also included a number of other species, which have now been transferred to the separate genus ''[[Zantedeschia]]''. These plants, from tropical [[Africa]], are however still often termed "calla lilies", but should not be confused with ''C. palustris''.
