Round Dell
Step into our jungle, densely planted with lush foliage-rich planting
Round Dell
When RHS award-winning garden designer Sophie Walker first read Frances Hodgson Burnett’s The Secret Garden (1909) as a child, she dreamed of creating a garden that captured the same sense of wonder and nature’s magic. That experience inspired her dramatic 2017 redesign of the Round Dell, where converging paths and oversized exotic plants dwarf visitors, integrating the ‘found space’ of a former quarry into the overall vision of the cultivated areas within the Garden. Walker aimed to create “an immersive place that opens up secrets, slowly and sequentially through the process of a journey.”
The result is a bold new architectural entrance into the Dell along a needle-shaped concrete path that echoes the front of a ship, steering through the heart of the lush, foliage-rich, jungle-like planting.
For an immersive experience that quickens the pulse, some paths are bordered by concrete raised beds that culminate in a sharp point, resembling a ship’s prow. Along one path, a waterfall adds an element of drama. With the assistance of plant collectors Bleddyn and Sue Wynn-Jones of Crûg Farm Plants, Walker incorporated newly discovered species with a strong emphasis on lush greenery.
“Something happens when you see green in all its shades; it forces you to zoom into detail and becomes a restful monochrome,” she explains. Gingers, Rodgersia, Persicaria, bananas, Gunnera, Fatsia, bamboos, and a variety of botanical oddities contribute to the Wonderland-like atmosphere of these dynamic planting beds.
“It’s lyrical,” Walker reflects, recalling the lasting impact of The Secret Garden. “It feels like walking into the actual book.”


Dig a little deeper
The Round Dell was originally a former quarry, sheltered and filled with subtropical planting thanks to the amount of water it retained. When Sophie Walker redesigned the space in 2017, she retained the rainforest lushness and existing plants like the Japanese angelica tree (Aralia elata), Japanese banana (Musa basjoo), bamboo, gunnera, Trachycarpus fortunei, Fatsia japonica, the veined Veratrum nigrum and several large-leaved Tetrapanax papyrifer.
A swamp cypress, Taxodium distichum, planted in the 1970s, rises over the back of the garden, fringed by Populus lasiocarpa (the Chinese necklace poplar), which has spreading, magnolia-like leaves and Magnolia macrophylla.
Here you will also discover exciting rare plant specimens found by modern day plant hunters, Bleddyn and Sue Wynn-Jones of Crûg Farm Plants in North Wales. These include water marginals Ligularia japonica ‘Rising Sun’ and Rodgersia podophylla ‘Crûg Colossus’. Other Crûg exotics planted in the dell include Aconitum arcuatum, a dark-purple monkshood from South Korea; Aralia apioides, with upright black stems and good autumn colour; Farfugium japonicum, with big, round dinner-plate leaves; hedychiums; schefflera; and the prehistoric- looking Zingiber mioga ‘Crûg’s Zing’, with yellowish stems and narrow leaves.
