Individual entries give each herb's common and scientific names and instructions for planting, growing, harvesting, and storing it. The entries also include ideas for using each herb in gardening and cooking (with occasional recipes) and discuss its medicinal uses. A special "insight" section that offers intriguing, often little-known facts about the herb rounds out each entry, as well as a color photo.

In addition to the individual herb descriptions, Garrett sets forth the basics of organic gardening, including pest control, and discusses how to design a herb garden and also raise roses, pecans, and fruit trees without chemicals. Of special interest are his instructions for making teas from dozens of herbs and his list of trees, shrubs, vines, and groundcovers with edible and/or medicinal properties. This wide range of information, not available for Texas herbs in any other single source, makes this book the perfect guide for homeowners, gardeners, landscapers, chefs, herbalists, and health care providers.
