The Native and Naturalized Orchids of Florida


This presentation features the native and naturalized orchids of Florida. Of the 110 native species and varieties of orchids found in Florida, Roger has photographed 96 of them, which has taken him from the far western panhandle to the lower Florida Keys.

Art holds a BS in Electrical Engineering from North Carolina State and an MBA from James Madison University. He founded Chadwick & Son Orchids Inc in 1989 with his father who has been growing orchids since 1943.

‘The Classic Cattleyas’ is widely considered to be the definitive book on large-flowered Cattleya species and was written by Art and his father. Martha Stewart favorably reviewed the book and had both Chadwicks on her TV Show.

Art has the distinction of naming Cattleya hybrids after the wives of the last five U.S. Presidents and personally presenting the flowers to most of the honored recipients. He is a ‘regular’ on the orchid society speaker’s circuit and has been fortunate to give lectures internationally (Western Australian Orchid Conference, World Orchid Conference in France). He is looking forward to speaking at the World Orchid Conference in Ecuador in 2017. Each month since 2002, the Richmond Times-Dispatch has published Art’s orchid advice column. The Winston-Salem Journal now also runs the popular column.

Chadwicks operates 11 greenhouses in rural Powhatan County, a retail store in Richmond, and boards over 13,000 orchids for local clients. The company was recently featured in Southern Living Magazine and the New York Times.
