An all-important plant directory then looks in greater detail at all of the main plant groups, including submerged plants, deep-water plants, waterlilies, marginal plants and moisture-lovers. There are also invaluable sections on other plants that can be grown in association with rock and water features, including ferns, ornamental grasses, trees and shrubs, and alpines. The plant entries are arranged alphabetically within each category, with clear descriptions of each plant, as well as essential information on hardiness, size, and care and cultivation. --
