choose these attractive and hardy native plantsas alternatives to potentially invasive aquatic speciesThese native aquatic plants can add beauty and interest to your water garden and are likely to be more hardy than

exotic plants. Nursery professionals can help you select plants native to your area. Harvesting native plants from the
