Grown them in the pool and in the ground. Hosta, with lobelia cardinallis white arum thrive in water....remove in winter though. Red leaves and flowers complement arum perfectly.
decent soil and added water during summer helps appearance and growth.
Size? They will make very large clumps and, as Hosta said, grow to at least a metre.
Warning! Slugs and snails are a menace
