Constructed to thrive
More than 400 species of plants live in the Dry Garden, all originating from areas of low summer rainfall, including the Mediterranean, South Africa, South America, Australia and California. Some of the larger plants found here, including the yuccas, pre-date the Dry Garden but have been kept as they suit the conditions and planting scheme.
The garden is constructed of coarse-grained gabbro boulders and subsoil mounded over rubble. The topsoil was mixed with a high volume of sand and grit to provide the plants with a free-draining environment.
