Ed Lawrence was the chief horticultural specialist to six governors general, from Jules Leger in the 1970s to Adrienne Clarkson in 2005.
He and the CBC's Hallie Cotnam met up with Rideau Hall's current manager of grounds and greenhouses, Mark Burleton, for a tour, which you can see in the photos above.
