rock garden

A rock garden is a garden designed to mimic a natural rocky hillside or slope, often decorated with rocks and adapted for specific plant types, such as alpines. Rocks are typically placed on their larger edges to appear as natural strata, with a few large boulders often being more aesthetically pleasing than numerous small ones.12

A well-designed rock garden provides varied exposures, accommodating both sun-loving plants like rockroses and shade-tolerant species such as primulas. Smaller perennial plants can fill the spaces within the rock faces. Common materials for construction include sandstone and limestone, with granite generally considered unsuitable due to its slow weathering. A rock plant is defined as a plant that grows on or among rocks or is suitable for a rock garden.23
