water lily

I’ve always wanted a container pond to grow water lilies…and this year I finally did it! This is my first experience with water gardening. I bought this container from Tractor Supply and filled it with this aquatic soil from Home Depot. Someone kindly gave me two water lily dividings for free...

I want to make a mini pond in a container with some water lilies (both regular size and dwarf) and other aquatic plants, similar to these container ponds: However, I'm having trouble finding dwarf water lilies to purchase. Does anyone know of a reasonably priced place I can get them? Thanks...
