Everything else was salvaged from dumpsters. They worked fine for the lower pond . I'm not sure how they will work for both ponds, but I'll probably need something bigger. I like to collect my own plants whenever possible. They seem to do better and if collected locally, and should over winter nicely in your pond.
Country roadsides are some of the best places to look.
We have collected many plants and met a few friendly folks in our travels. We found the white water lily growing in a drainage ditch in south Georgia along with tall cat tails. Some water plants are considered pest in many parts of the country and in our state, Georgia, it is illegal to dump your excess pond plants into state waterways. Once most pond plants get established, they will multiply, and you will end up with more plants than you have room for. We have several friends who also have ponds and sometimes trade plants with each other.
