The garden of Charles and Cary Owen is located in Biltmore Forest, adjacent to the Biltmore estate. Charles Dexter Owen is a cousin of Charles Owen Dexter, hybridizer of the Dexter rhododendrons at Heritage Plantation on Cape Cod. The Owen house, constructed in 1936, sits in the middle of the largest collection of Dexter hybrid rhododendrons in the south, exceeded only by the original Dexter garden on Cape Cod which provided the plants "by fully loaded box cars".
