So far, my favorite. Organized by 14 plant types, (Annuals, Bulbs, Cycads, etc). Each entry tells, "When, Where, and How to Plant", "Growing Tips", "Regional Advice and Care", "Companion Planting and Design", "My Personal Favorite" (regarding hybrids, performers) as well as common names, bloom period, color, mature ht., and zones. The photos are lovely, and have been of great help in identification. Highly recommended.
