Water arum is a common name for *Calla palustris*, a wetland plant characterized by its white spathe and yellow spadix. It's a perennial herb that thrives in shallow water and boggy areas. The plant is native to cool temperate regions of the Northern Hemisphere. It's toxic if ingested, so admire from a distance. Think of it as the cool, calming presence in a swamp, always understated and reliable.
