    This is an outstandingly beautiful piece of craftsmanship – a focal point of beauty and tranquillity for any garden. I bought this in memory of my parents, and they would have loved it and admired it as much as I do. Truly worth every penny.

About The Collection

The products in the RHS Welsh Slate Collection were chosen to fit a theme of mindfulness and wellbeing at home, with more and more of us turning to our private gardens as havens for peace and tranquility.

The real beauty of Welsh Slate is its natural ability to enhance both traditional and contemporary settings. The RHS Welsh Slate Collection is curated from hand crafted pieces of genuine natural stone, hand selected in Wales by Welsh hands.

Window Stones, Stepping Stones and Slate Benches work perfectly in traditional British gardens, as well as Japanese or Zen themed designs. They work equally well when adding texture and organic tones within clean, contemporary landscapes.
