Vallisneria. Richard Lee, biologist and owner of Wm Tricker, Inc.®, took the video of our native Vallisneria in one of our local rivers here in Ohio and would like to share this video with you. The video shows one of the MOST Amazing and soothing sights in Nature: Vallisneria and a River in harmony. Walter Pagels, prominent world aquatic specialist from California, also enjoyed this video and commented that this video is a most wonderful display of Vallisneria in Nature. He also agreed that every water garden pool should have Vallisneria!
