Job: Creating a perennial garden.
Contractor: Hortech Landscapes, with help from the Trentham horticultural team
Designer: Piet Oudolf
Value: Part of a £100m restoration of the estate
International garden designer Piet Oudolf has stamped his signature style on Stoke-on-Trent by using grasses in a scheme for the Trentham Estate's perennial garden.
The 3ha garden boasts a water meadow featuring swathes of moor grasses, including Molinia caerulea subsp. caerulea 'Edith Dudszus' and 'Heidebraut', intermingled with colourful meadow plants.
This "river of grasses" moves on to a floral "labyrinth" of thousands of colourful perennials, including Persicaria polymorpha and Sporobulus heterolepis.
Gardens manager Michael Walker said: "The completion of Oudolf's vision really confirms Trentham's place alongside the best gardens in Britain."
Plans for the garden first emerged four years ago but Oudolf was forced to go back to the drawing board when the Environment Agency warned the estate in its second year of restoration about the increased flooding risk to the garden.
Walker said: "Due to climate change, the area along the River Trent is likely to flood much more frequently in the future so we took a step back and gave Piet a new brief. Part of it was to include plants strong enough to cope with more flooding. We also wanted a garden that was for the whole family."
Crocus supplied the plants for the design, which marks the latest milestone in the restoration.
