Anyone who has witnessed the stark, sere low desert landscape transformed into a kaleidoscope of colors by annual wildfl owers is not likely to soon forget the experience. Once affl icted, the wildfl ower junkie can only count the days, months and, oft times, years that pass between fi xes of fl oral fantasy.
