About the garden

Owned by
National Trust

Designed By
Capability Brown

One of the last country estates in London, Osterley's 18th century Robert Adam house is surrounded by 350 acres of parkland, farm and gardens. Features include the Garden House with its tender plants and collection of lemon trees, American Border of rare North American trees and shrubs, a walled garden with herbaceous borders and ornamental vegetable plots. The Winter Garden injects colour into the colder months.    

The many fine trees include cedars, oaks, Picea omorika and oriental plane planted in 1755 whose lowest boughs have swept right down to ground-level and taken root before turning skywards again. In early spring the Long Walk is carpeted with bluebells. The walled potager garden is not to be missed with its eye-catching mix of traditional plantings, ornamental vegetables and bright obelisks.
