With the exception of Azolla, Duckweek and Salvinia, surface types are shipped bareroot or in bunches of unrooted cuttings. No planting is necessary - simply float these items in your pool.
For some items such as Parrot's Feather, Water Hawthorne & Creeping Jenny, you may prefer to pot them for better results. Azolla, Duckweek and Salvinia can be purchased by the pound in plastic bags or in portions attractively packaged in clear plastic 4" cups with colora labels on th etop featuring a photograph of the plant, as well as a cultural explanation. A small amount of water should be added ot these cups upno arrival and they should last for several weeks under these conditions.
