This fourth edition of Steven Still's book has expanded the great depth of the widely used and accepted third edition. There are hundreds of additional plants, hundreds of more drawings, and twice as many color prints as the previous edition.

This is the one book that provides information about common and uncommon annuals, biennials, perennials, bulbs, ornamental grasses, herbs, and hardy ferns that are adapted to the climates of the United States and Canada.

This 814-page book with 384 color prints has become the standard in the field and its usefulness goes from the classroom to the professional to the interested amateur.
