Growing it

Propagation: seed, division
When to plant: spring
Overwintering: In cold climates, move the container to the bottom of the pond where the water does not freeze, or bring it into a cool, frost-free garage. Keep the rhizomes moist but not necessarily submerged during the deepest part of winter.
In containers: It is excellent for containers, provided you use a wide, bowl-shaped pot with no drainage holes and keep it filled with water.

Seed

Carefully file or nick the hard seed coat until the white inner layer is visible.
Place the seeds in a glass of warm water, changing it daily.
Once sprouts appear, plant them in a small pot of heavy clay soil submerged in shallow water.

Division

Wait until the plant is dormant in early spring.
Gently lift the rhizomes from the mud, being careful not to break the growing tips.
Cut a section of rhizome with at least two healthy nodes and replant immediately.

Group plants by their water depth requirements to ensure each species stays in its preferred zone.

Grows well with

Water Lily · They share similar water requirements and create a beautiful contrast in leaf shape.
Pickerelweed · This marginal plant adds vertical interest around the edges of the pond.

Similar species

Water Lily · Often confused with lotus, but water lily leaves have a distinct notch and float directly on the surface.
