The botanical garden in Bradenton, Florida is known as the Palma Sola Botanical Garden. In 1868 a firearms manufacturer named James Warner along with his family moved from Springfield, Massachusetts to Manatee County. He made his home along the Manatee River but ended up dying a year after moving. His son Warburton S. Warner would end up creating a town called Palma Sola in 1884 on part of the family's homestead. It got its name from a "single tall date palm that dominated the skyline on Snead Island" located directly across the river from McNeill Point where the center of town was located at.
