Bog arum’s close relatives are Zantedeschia, which are very common in our flower shops. Its flowers form a roll-shaped small inflorescence or a spadix. Under it, there is a large coloured floral leaf, attached to the inflorescence stem. Its fruit is a red cylindrical cluster of berries, which turns bright red in August. Its berries are poisonous.

Bog arum grows in bogs, ponds, and on the shores of waterbodies.
