Waterlilies, lotus, submerged, floating and marginal water plants all get their due in this lavishly illustrated encyclopedia by Water Gardening Magazine founders Greg and Sue Speichert. Each category of plant is discussed in its own chapter, with information about its proper soil, planting and climate requirements. Much of the book is given over to descriptions of various species, and home gardeners should especially appreciate the book’s useful appendixes, which list plants for special places, such as table-top ponds, as well as by their colors. 707 color photos.
