Specific to the conditions and facts of each palm, the late Robert Lee Riffle handed us a detailed, quick reference before he left the world stage.
I like this book because each palm I look up has the climate zones it can survive in, the growth rate, the color of ripe seed, the germination time and much more bullet head information of the plant.
After the vital profile comes the aesthetic overview that only Mr.Riffle could give us...a view of the unique beauty of each palm.
Adieu, Robert, and thank you.
