A rockery is a garden feature that consists of a collection of rocks and stones, often arranged to create a natural-looking landscape. It typically includes various types of plants, especially alpine plants and succulents, which thrive in rocky environments. Rockeries can enhance the visual appeal of a garden and provide a habitat for wildlife. These structures can vary in size and design, from small decorative arrangements to large, elaborate formations. Rockeries are often used to improve drainage in gardens and can help prevent soil erosion. They are popular in landscaping for their aesthetic value and low maintenance requirements.
