The California Nursery Company in Niles supplied many palm trees for the Panama Pacific International Exposition. In the 1915 catalog, there is a photo of Canary Island palms on a railcar. It says "Trainload of large Phoenix canariensis. Were planted on Palm Avenue at 1915 Exposition."
"In the fall of the year most of large trees for the Avenue of Palms were boxed. This called for about 350 Canary Island date palms and California fan palms, which were set alternately. Most of them were shipped from Niles, on the east side of the Bay, in the spring and summer of 1914." (Page 310, of The Story of the Exposition: Being the Official History of the International Celebration Held at San Francisco in 1915 to Commemorate the Discovery of the Pacific Ocean and the Construction of the Panama Canal, Volume 1.
