Burr developed his interest in cultivating and hybridizing orchids into a business with Benevides. Over 20 years, their company, Sea God Nurseries, had nurseries in Fiji, Hawaii, the Azores, and California, and was responsible for adding more than 1,500 new orchids to the worldwide catalog. Burr named one of them the "Barbara Hale Orchid" after his "Perry Mason" costar. Burr and Benevides cultivated Cabernet Sauvignon, Chardonnay, and grapes for Port wine, as well as orchids, at Burr's farmland holdings in Sonoma County, California.
