Slate Boulder SB15 is a small round and rather flat piece of slate hand picked from a quarry in South Wales.  This shape normally makes for a Slate Pyramid base, but this particular piece stood out as one that would work very well on its own. This would suit a small size garden design perfectly, near a seating area or patio to maximise the benefits of water and natural stone.

LED Lighting and Small Reservoir Pack available in the Basket.

Delivery & Returns Info

Slate Boulder SB15 was initially chosen in a South Wales quarry as a base stone for our Slate Pyramid water features, but the unique colour and detailing in this stone stood out enough to make it a stand alone ornament in a small garden design. Used with decorative gravels and careful planting, this small stone water feature could be the focal point in a townhouse or terrace garden where gardening space is limited.
