If you are not familiar with this book --- meet a behemoth. Weighing in at a whopping ten pounds, this great classic is now in its fourth edition. The full subtitle is "Color Cyclopedia of Exotic Plants and Trees for Warm-Region Horticulture --- in Cool Climate the Summer Garden or Sheltered Indoors." It expresses the author's intention that these lovely plants be grown and appreciated by all, not just tropical dwellers.
