Gardens can contain flowers, plants, herbs, vegetables, and decorative elements. Using pebbles in a garden brings different colors and textures to the garden. It can also fill up an otherwise empty space in the garden, leaving a visual that might be considered more interesting and aesthetic than simple dirt, soil or mulch.
It serves other purposes, such as creating a decorative border or a landscaped path, providing a pretty ground and soil cover, and providing dry garden beds. Pebbles are currently very trendy, with landscape designers using them as mulches, in mosaics and paving, and to surface paths and driveways.
