There were no plans available at first for the Great Plat.
Madeleine drew up a plan based on the 1908 Country Life text and photographs, which provided evidence for a planting of peonies, china roses, delphiniums, lilies and bergenia.

The Great Plat and pergola restored, 1974.
The Bergenia schmittii were lifted, divided and replanted around the edges of the beds. Within the bergenia frame, Paeonia albiflora gave pink colour in spring, while in summer the reds and oranges of lilies, cannas, gladioli and Phlox drummondii ‘Scarlet' made a vibrant display contrasted with blue delphiniums and white lilies.
