How to Grow the Wildflowers
Specific to the Southwest, How to Grow the Wildflowers, by Eric A. Johnson and Scott Millard (Ironwood Press, 1993; $17), describes over 180 flowers that are native or adapted to the desert. This book covers how to plant; requirements for soil, sun, and water; and flower bloom time and growth habit. There's a helpful section on designing with wildflowers as well as information on different climates of the Southwest.
The Lady Bird Johnson Wildflower Center
This nonprofit organization was founded to promote the beauty as well as the environmental and economic importance of native plants. Its Web site (www.wildflower.org/) contains articles on using native plants, such as "Wildflower Meadow Gardening" and "Planting Wildflowers along Roadsides." The site's searchable database provides brief descriptions of native plants. The center, located in Austin, Texas, offers workshops for educators, tours for school groups, and events for the entire family, all of which are listed on the site.
