Penjing: Worlds Of Wonderment, by Qingquan Zhao, Hard Cover, 144 pages, full color illustrations. This book is, hands down, the finest text ever written on the Chinese approach and techniques for bonsai.

To completely understand the art bonsai, you must understand penjing and the Chinese approach from which it developed. That makes this one a must buy.
