Acorus gramineus

This is taller than pusillus but needs very similar growing conditions. This plant seems to do very well as a pond plant where it can be grown in the very shallow edges of the pond with its leave out of the water. Care should also be taken not to bury the rhizome in the substrate. This species seems to flower more readily than the other species, but does not set seed in our conditions (possibly needs a specific pollinator). It is fairly easy to propagate by separating rooted parts of the rhizome but this also sets the plant back.
