Robert Lee Riffle

Robert Lee Riffle (1940–2006) was an internationally recognized authority on palms and tropical plants. His landmark book, The Tropical Look: An Encyclopedia of Dramatic Landscape Plants (1998), won an American Horticultural Society Book Award, as did An Encyclopedia of Cultivated Palms (2003), which he co-wrote with Paul Craft. For 25 years Bob was a strong presence online, answering questions and encouraging gardeners in their endeavors via postings on garden and plant message boards. He generously shared his extensive knowledge gently and with wit as the moderator of the International Palm Society’s active PalmTalk message board. Bob was an accomplished pianist, a gifted photographer, and an enthusiastic film buff. He had finished writing the manuscript for the Timber Press Pocket Guide to Palms when he passed away unexpectedly.
