I find this book to be an excellent reference. It covers the seven principles of plant selection. Type of plant, hardiness, height, soil and moisture, care and interest. It lists a variety of plants for full sun, mostly sunny, mostly shady and full shade. Inside these categories you will find annuals, perennials, herbs, vines, groundcover, shrubs and trees. This book makes it easy to select the "right plant" for the right place without a doubt!
