Description
Bring a soft, natural finish to your outdoor space with our Highland Pebbles in a generous 20–30mm size. This attractive aggregate blends cool greys and browns with soft plum, mauve, cream, and warm buff tones, creating a beautifully varied, multi-tone surface full of natural character. With its smooth, rounded pebbles in a larger size, this Highland Pebbles blend offers a bolder, chunkier look that suits everything from traditional cottage gardens to clean, contemporary schemes.
The naturally rounded stones give this blend a smooth, comfortable feel and a soft, organic appearance, while the bigger pebbles add real presence and impact. When dry, the mix offers cool, muted tones with subtle warmth running through; once wet, the colours deepen and come alive, bringing out the full range of greys, browns, and creams for an even more characterful finish. This soft, versatile palette complements almost any paving, planting, or building material, making it a popular and adaptable choice.
Practical and hard-wearing, the larger Highland Pebbles are a lovely choice for bolder features. Use them to dress borders and beds, create decorative features, top larger pots and planters, or finish around water features and ponds, where their smooth, rounded character feels perfectly at home. The bigger size makes them particularly effective as a statement finish and for controlling larger areas.
As well as looking great, these pebbles are low-maintenance and free-draining, helping to suppress weeds and keep surfaces neat throughout the year. The larger 20–30mm size gives excellent ground coverage and a bold, natural finish that works beautifully in feature areas and across larger spaces.
Supplied in convenient bulk bags or large packs, our Highland Pebbles make it easy to order exactly the right amount for projects of any size. As a guide, we recommend a coverage depth of around 50–60mm for the larger 20–30mm pebbles.
