These materials were in the possession of Betty Pooler Mitchell Nehrling, Henry Nehrling's second wife. Dr. Henry Nehrling was a horticulturist famous for his gardens in Gotha and Naples, Florida. The collection consists of letters, documents, photographs, postcards and monographs which provides insight into the familial and financial affairs of the Nehrling Gardens. It also offers a look at Henry Nehrling during the tumultuous years of Florida's boom and bust, and a glimpse of his failing physical and mental state while he sought refuge in a quiet communal colony in Southwest Florida.
