Bottom House, Bix

This is a spectacular September garden. There are pots in profusion and the immaculate lawns are surrounded by borders filled with late-summer flowering perennials, with quantities of semi-hardy plants particularly Salvias. On a terrace by the house are huge pots of Brugmansia, which at this time of year are the glory of this garden. 

Crockmore House, Fawley 

Christopher Bradley-Hole designed this garden 22 years ago with grasses and perennials laid out in a formal grid bed, progressively reaching a crescendo in September. Block plantings of various Miscanthus and Pennisetum grasses are punctuated with the muted colours of Eupatorium purpureum, Lythrum salicaria, Sedum and Salvia, with wonderful Asters in bright pinks and purples. 

The Mill, Medmenham

The Mill, built of mellow brick and nestling under a well-wooded bank of trees at the end of a long yew-shrouded mill race, is utterly charming. The main garden lies below the house, with new borders of late-summer flowering perennials and grasses, including Mollinia ‘Heidebraut’ which turns a brilliant straw-yellow in the autumn. The large pool, fringed with marginals, is overhung by a Liquidambar and a spectacular Pterocarya fraxinifolia.
