Growing it

Propagation: seed, division
When to plant: Spring
Overwintering: If the pond freezes, move the container to a deeper part of the water or a frost free area to prevent the rhizomes from freezing solid.
In containers: It grows very well in containers, provided you use a large, wide pot with no drainage holes to keep it submerged.

Seed germination

Carefully file the hard outer seed coat until you see the white inner layer.
Place the seeds in a glass of warm water.
Change the water daily until sprouts appear.
Plant the sprouted seeds into a container of heavy clay soil once they have roots.

Group aquatic plants by their preferred water depth to ensure all species receive adequate light and nutrients.
