Designer Sophie Walker is creating an immersive experience for visitors to Borde Hill Garden near Haywards Heat in West Sussex. Her design for the exotic Round Dell includes an arrow shaped, gravel path that will lead to a concrete pool fed by a waterfall. The contemporary-looking path with concrete sides will give visitors the chance to explore fully the subtropical, foliage-rich planting, which will become denser and more jungly as the path narrows, and will include species collected by Bleddyn and Sue Wynn-Jones of Crug Farm Plants.
