The approach to Giardini Pistola is along a winding drive, through vineyards, in the unspoilt valley of Canale di Pirro in the Puglia region of southern Italy, with a backdrop of gentle hills covered in downy oak woodlands, where wild boar roam free. These terraced gardens, designed by Urquhart & Hunt, were carved out of a sloping meadow four years ago, and are an exciting experiment in planting that combines Mediterranean and English garden styles.

Designers Lulu Urquhart and Adam Hunt − best known for winning Best in Show at RHS Chelsea in 2022 for the beaver-inspired A Rewilding Britain Landscape − were invited by owner Constant Tedder to create the garden below the restored farmhouse and connected trulli (Puglia’s distinctive cone-shaped stone huts). The top section of the 8m slope had already been landscaped as three interconnecting terraces, while the rest was still an expanse of bare soil.

The design ensures that the visitor’s journey up and across the terraces is one of discovery.

“There’s a magic to the landscape here, a permanence, a history, with field after field of ancient olive trees, some over a thousand years old,” explains Adam. “The owner wanted to create something absolutely beautiful that provided a series of different experiences across six terraces.”

Traditional trulli stone huts, skilfully renovated as holiday rentals, provide the backdrop to the top terrace. The borders offer a gentle screen between the private and public realm with taller plantings of Stipa gigantea and Molinia caerulea subsp. arundinacea ‘Black Arrows’ underplanted with deep reds and burgundy of Oenothera lindheimeri Gaudi Red (= ‘Florgaured’), Lobelia tupa, Thymus Coccineus Group, Teucrium marum and Origanum vulgare ‘Zorba Red’. ©Jason Ingram

It was intended to make it an open garden for the public to visit, and as well as a space for functions, the wishlist included an amphitheatre, a child-friendly water feature, a maze, pergolas with edible and ornamental climbers, and elements of discovery. While Adam started to conceive the masterplan, the planting design team (Valerie Bond, Petra Ulrik and Lulu) researched possible plants for Pistola’s challenging temperature range of between -10°C and 40°C, and its recent increases in springtime rainfall.

We wanted people to meander and on occasions be surprised about where they came out; to take time to experience the landscape of this special place.

With feedback from local nurseries and inspiration from French nurseryman Olivier Filippi’s drought-tolerant catalogue, they drew up a list of plants that should survive with no irrigation once established. “We found it hard to judge the exact hardiness when it comes to heat and frost, and no irrigation,” says Lulu. “The hardiness charts often don’t reveal that.”

Grass terrace surrounded by countryside
The Grasses Terrace features this matrix of three grasses: the biscuit-toned Calamagrostis x acutiflora ‘Karl Foerster’, providing a vertical accent; the fine, textured, green foliage of Miscanthus sinensis ‘Gracillimus’; and the buff haze of statuesque giant feather grass Stipa gigantea.

The greatest challenge, however, was using only plants that are not affected by or host to the Xylella fastidiosa pathogen that has already devastated olive plantations in parts of southern Italy. Banned plants include other star players of Italian gardens such as lavender and oleander. “This is where our passion for ecological balance and future-proofing gave precedence to our design,” explains Lulu. “Every plant we selected would not be a host to Xylella.”

Italian garden in bloom
A 64m-long rill, constructed from local limestone, forms the Canale, the formal heart of the garden. Mirror beds on either side ripple with plantings of mauve-flowered Salvia abrotanoides, creeping thyme Thymus serpyllum and yet-to-bloom Calamintha nepeta. The mastic trees (Pistacia lentiscus) are intended to create a sense of presence once they are mature. ©Jason Ingram

Finally they drew up a very detailed planting plan and handed it over to the gardening team at Giardini Pistola. Covid restrictions at the time meant that the designers could not travel to oversee the planting, but with project manager Ollie Stroud and a skilled team of Italian landscapers on the ground, the results
were beyond their expectations, and in June 2021, the garden opened to the public.

There’s a magic to the landscape here, a permanence, a history, with field after field of ancient olive trees, some over a thousand years old.


A wander up the garden from the bottom of the terraces reveals the fascinating mix of plants that made the final list. In the majority of the terraces, which are all 80m x 22m, the planting palette comprises between five and 13 species that are used in simple, repeated combinations to soften the linear nature of the garden.

Italian garden path bordered by trees and shrubs
The organically shaped beds in the Naturalistic Terrace create winding paths that invite visitors to immerse themselves in the layered planting that spills around key trees, such as x Chitalpa tashkentensis Summer Bells (= ‘Minsum’), that link visually with the woodland in the hills beyond. Mounds of drought-tolerant perennials, including santolinas and Pseudodictamnus, combine with grasses that reach a crescendo of bleached tones in late summer. ©Jason Ingram

The design also ensures that the visitor’s journey up and across the terraces is one of discovery. “We wanted people to meander and on occasions be surprised about where they came out; to take time to experience the landscape of this special place,” explains Adam.

Crushed limestone paths provide a network of different ways to navigate the terraces and the interlinking slopes. The same white stone, luminescent in the southern Italian light, has been used to pave the steps and build the walls.

The first level is conceived as a Play Terrace, with a maze of clipped Italian buckthorn (Rhamnus alaternus ‘John Edwards’) and an in-ground trampoline. Banks of planting are used to create the level changes between each terrace. “The bank plantings have their own identity,” explains Lulu, “with reference plants from the planting choices of the terraces above and below.” This helps to blend
the transitions between the terraces and gives cohesion to the whole scheme.

Steel pergola tunnel
Two mild-steel pergolas, planted with a succession of climbers such as bottle gourds, kiwis and Rosa banksiae var. banksiae create verticality in the Tunnels Terrace and provide linear routes through the space. They are softened with Rosa Crystal Fairy (= ‘Spekren’), Rosa The Fairy Tale Rose (= ‘Poulcas065’) and red-flowered Glandularia peruviana, which spill across the paths. ©Jason Ingram

The bank between the Play Terrace and the Naturalistic Terrace above it, for example, combines white-flowered Mediterranean gum cistus (Cistus ladanifer) with white gaura Oenothera lindheimeri and statuesque Leonotis leonurus with its zingy orange blooms, with the cistus repeated in a simpler planting with Erigeron karvinskianus in the next terrace up.

This level, which features a series of organically shaped beds, is a celebration of form and texture. Exotic-looking trees such as x Chitalpa tashkentensis Summer Bells (= ‘Minsum’) and foxglove tree (Paulownia tomentosa) emerge from mounds of grey-green and silver-foliaged plants, such as Artemisia abrotanum, Pseudodictamnus hirsutus and Santolina pinnata subsp. neapolitana ‘Sulphurea’, many sourced from Olivier Filippi’s nursery.

grass amphitheatre
The grass amphitheatre, used for events including star-gazing, is planted with Bermuda grass (Cynodon dactylon). Known as gramigna in Italy, this is a perennial grass with underground rhizomes that enable it to survive drought conditions. The banks echo the shape of the gentle hillscapes that frame this beautiful valley bowl. © Jason Ingram

Next, the winding paths give way to the formality of the Canale. On this terrace, an elegant central rill made from local Rici limestone is shallow enough for children to play in safely. Set along an east/west axis, the water provides stunning reflections from the sky. The lines of mastic trees (Pistacia lentiscus) in the linear borders either side are underplanted with a romantic mix of English roses in peachy shades, alongside whites, blues and purples from pale Agapanthus ‘Nana Blue’, Russian sage, Geranium x cantabrigiense ‘Biokovo’ and G. sanguineum ‘Album’. Plumes of golden grass Stipa gigantea in the bank leading up to the next terrace anticipate this plant’s dominant role on the upper terraces where, as summer progresses, it arches ever higher, providing playful vertical accents.

The Tunnels Terrace features a pair of mild steel pergolas that support various climbers, including roses and edibles such as bottle gourds and kiwis. In contrast to the straight paths through the pergolas, the routes through the central beds wind and turn, providing a jungle-like experience, especially in late summer when the matrix of grasses rises to a crescendo of green, gold and bronze. Above this lies an open space shaded by plane trees, where large-scale events are held, and at the top of the garden, planting in the Grasses Terrace provides a bold screen in shades of red and gold between the public garden and the holiday accommodation above.

On the west side of the terraced garden is the grass amphitheatre planted with drought-tolerant Cynodon dactylon, while on the east side a romantic mount offers an elevated view across the whole garden, revealing myriad pathways that ensure that visitors can explore every corner of this exuberant garden.
