Henry Morrison Flagler built tourist hotels at St. Augustine in the late 19th century, including the Ponce de León Hotel. He needed a local source of fresh vegetables for his guests, so he persuaded Thomas Horace Hastings, his cousin, to develop a farm. A small community evolved into a town, which was named for its founder in 1890.
