Keep soil consistently moist to waterlogged. This plant thrives in wetland environments and can tolerate standing water for extended periods. Ensure adequate moisture, especially during establishment and dry spells.

Pruning is typically done for management or aesthetic purposes, such as reducing spread or removing dead material. Cut back dead stems in late winter or early spring before new growth emerges.

Avoid cutting into the soil as this can encourage rhizome growth.

Easily propagated by rhizome division in early spring or fall. Seeds can also be sown, but vegetative propagation is more common for establishing desired characteristics and controlling spread.

Not typically grown in pots. If containment is necessary, it requires very large containers with restricted root systems. Repotting is not a standard practice for this species.
