A perennial is a plant that lives for more than two years. Perennials are flowering plants which grow and bloom over the spring and summer and then die back every autumn and winter. They typically grow structures that allow them to adapt to living from one year to the next through a form of vegetative reproduction rather than seeding. Perennial plants often have deep, extensive root systems which can hold soil to prevent erosion, capture dissolved nitrogen before it can contaminate ground and surface water, and outcompete weeds. They grow very well in conditions that are poor in resources due to their earlier emergence in the spring, and the development of larger root systems which can access water and soil nutrients deeper in the soil.

"Whow I bought some plants for my pond earlier on and they are doing fine. then I got these as they sink to the bottom the pond and should bring oxygen to what lives in it. but they looked dead. so I bought some more. and now not only the fish are eating it but the frogs but it's better to have oxygen than none at all. it's just my fish????"

"Good sized bunches and having the lead weight means they sink to where you need them. They are already doing their job releasing oxygen."
