Slate boulders

Enhance your outdoor space with our stunning slate boulders, sourced directly from the historic Lantoom Quarry in Cornwall. Each slate boulder is naturally formed over millions of years, featuring a beautiful and distinctive blend of earthy brown and cool blue tones. These rich colours create an eye-catching focal point that suits a wide range of landscaping styles, from traditional country gardens to contemporary outdoor spaces.

Our slate is renowned for its beautiful earthy colours, making these boulders ideal for long-lasting garden features. Their rugged texture and organic shapes add instant character, whether they are used as standalone statement pieces, placed in clusters, or incorporated into pathways. Slate boulders are also incredibly popular in Japanese-inspired gardens, where their calming colours and natural forms help create serene, balanced environments. They work perfectly in Zen gardens, rockeries and ornamental landscapes, offering a tranquil, grounding presence.

Because every slate boulder is unique, no two pieces will ever look the same. This allows you to design a truly bespoke outdoor setting tailored to your own style. Whether you’re aiming for a subtle, natural feature point or a dramatic landscape centerpiece, our slate boulders offer versatility and timeless appeal.

We supply a wide range of sizes to suit all types of garden projects. From impressive large slate boulders that serve as bold structural elements to small slate boulders ideal for detail work, edging, or decorative borders, we can provide exactly what you need. If you’re unsure which size or style is best for your project, simply get in touch with our friendly and knowledgeable team. We’re always happy to help guide you through the options and ensure you choose the perfect boulders for your garden or landscaping design.
