Dumbarton Oaks. Georgetown, Washington, DC, US.
Beatrix Farrand was one of the great landscape designers. If you can get to only one of her gardens, make it Dumbarton Oaks in Washington, DC. This is where I first became aware of her work. The moment I passed through the orangery into the Green Garden, one of many garden rooms and spaces, I could feel her brilliance. She provides reassuring formal spaces, open naturalistic areas, and even works in a lovely orchard. Each space flows seamlessly into the next. And no detail is too small.
