These plants normally grow in one to three feet of water, however, some species can grow in much deeper water. Shallower than recommended planting may result in leaves held above the surface and poor flowering. Water lilies and lotuses, along with Golden Club, Water Hawthorn, and Water Fringe are examples of this group. For further information on deep water plants, select the propper plant from the navigation area to the left.
