An aromatic terraced area studded with boulders and scree
The plants in the Boulder Garden complement the Mediterranean theme inside the Great Glasshouse. However, these warm climate loving plants are not sheltered by anything and would usually struggle to grow in Wales’s cool, damp climate. So gardeners have had to think very imaginatively.
The stony soil of the Boulder Garden helps water to pass through quickly, reducing the chance of winter damage. This helps prevents frost damage to bulbous plant species native to Southern Europe, such as cyclamen, crocus and colchicum.
The sunny south-facing slopes suit shrubs like cistus and juniper, whilst hellebores and euphorbias favour shade.
