One young, viable Nymphaea ‘Ploydaeng’ hardy water lily rhizome with a healthy crown and 1–2 actively growing leaves, ready to plant upon arrival for strong and immediate growth.
All water lilies are shipped bare-root (as tubers) and should be planted immediately upon arrival for best results. Bloom and leaf color, size, and shape may vary slightly depending on lighting, water quality, and plant maturity.
Certain aquatic plants may be restricted or regulated in some U.S. states. Always check your local and state regulations before purchasing or introducing plants into natural waterways. Never release aquarium or pond plants into the wild.
There are two main types of water lilies, tropical and hardy. The differences between tropical and hardy water lilies are a growing habit. Tropical water lilies don't do well in winter. Hardy water lilies, on the other hand, can tolerate the cold. Tropical water lilies tubers must be removed from the pond and stored in moist conditions to come back in the future years. In warm climates, they can remain in the pond.
