To study garden design is to perceive (visually and otherwise) garden form and explore the many forces that have influenced the creative process. A sense of place that a garden can create and the form of a garden can only be fully understood by studying the culture and the individuals that created it. Then it is possible to apply this knowledge of garden history to the evaluation of the materials and spaces of today’s gardens and landscapes.
