The scope of gardening information in The Brooklyn Botanic Garden Gardener's Desk Reference is nothing short of amazing. For easy use, the wide-ranging material is divided into 20 sections and contains informational sidebars, tables, plant lists, maps, and illustrations that will prove indispensable. Take, for example, growing conditions. Because of the diverse growing conditions in the United States, all plant lists in the book are organized according to region, and every recommended species or cultivar has been chosen by an experienced landscaper and tested in that region. This reference is a must for any new or experienced gardener on your Christmas list.
