Thanks ... the ponds have pumps during the winter to prevent the water from freezing solid. Yes, all of the extra lilies I sell come from my parent plants. The 3 other ponds not shown are 8x8, 4x10, 4x8 & are the wood/liner construction. Much easier for me to do above ground--I don't like to dig. I do like to collect lilies, so that is why I've got so many lily ponds. I keep regular goldfish in with the lilies plus mosquito fish. I the winter I put on PVC hoops & cover with plastic on the wood ponds to give them a "greenhouse" effect.
