Plum Slate 20mm Granite arrives in a 750kg bulk bag, perfect for pathways, driveways, and borders. The warm plum and purple tones add rich colour to any garden. Order today for just £230 with free UK delivery.

Made from 15-35mm natural slate granite chips, this aggregate suits both decorative and practical drainage applications. The angular chips interlock underfoot, forming a stable surface that resists displacement. Spread at 40mm depth, one bag covers around 14m² — enough for a generous garden path or border surround.

These stones are fish-friendly once washed, making them suitable for pond edges and water features. Plum slate develops a deeper, richer hue when wet, giving your garden a striking appearance after rainfall. The warm purple tones pair well with silver-leaved plants and contrast beautifully against sandstone paving or timber decking.
