“Uncontrollable changes in a garden are inevitable and wonderful opportunities,” says Donald Pell, a landscape designer in Chester County, Pennsylvania. To prove this is true, Donald and his associates created an incredible series ofnaturalistic gardens around their studio. This landscape has become an invaluable laboratory where Donald and his team learn from failures and from the many years of watching this landscape design evolve. “Establishing a garden based on an initial plan (perhaps one even scribbled on paper) is a great place to start, but as plants, the setting, conditions, our knowledge, and our tastes change, so should our designs,” Donald says.
