20mm Plum Slate Chippings

Add refined texture and subtle colour to your outdoor space with our premium 20mm Plum Slate. Carefully sourced from the historic slate quarries of the North Wales mountains, this decorative aggregate reflects the natural beauty and rugged charm of one of the UK’s most striking landscapes.

Featuring a blend of rich plum, soft heather, and gentle grey tones, each piece echoes the layered rock faces and rolling peaks of Snowdonia. The 20mm size offers a finer, more compact finish than larger grades, making it perfect for pathways, borders, pots, and areas where a smoother look is preferred.

Hardwearing and easy to care for, plum slate is a practical choice as well as a decorative one. It stands up to the elements, requires minimal maintenance, and its natural tones intensify when wet—bringing out deeper, more vibrant colour after rainfall.

Ideal for both modern and traditional garden designs, our 20mm Plum Slate brings a subtle yet distinctive connection to the timeless scenery of North Wales.
