Osterley Park's formal garden was transformed during a six-year project from an overgrown wilderness back to its 18th-century grandeur with herbaceous borders, roses and ornamental vegetable beds. With bulbs springing to life in the garden throughout the year and garden buildings to explore, there's plenty to enjoy whatever the weather.

Autumn in the Garden

This time of the year, Osterley’s gardens are brimming with warm and fiery colours from oranges to reds. In front of Robert Adam's Garden House, the fiery red North African Sassafras albidum is a showstopper as it bursts into colour and makes a stunning photo location. One of our standout champion trees - Shagbark Hickory also displays its beautiful soft butter-yellow tones for a picturesque moment under its canopy in August. There are numerous exotic shrubs and trees to look out for during this season. Still, the highlight of the season, with September and October being the best months to see it, is the Ornamental Vegetable Garden.

The Garden House

This semi-circular building, built in 1780 and designed by Robert Adam, is a fascinating feature of the garden set among the borders of Mrs Child’s Flower Garden. Used to entertain guests, Mrs Child filled the Garden House with exotic scented plants, including grapes, pineapples and, according to the 1782 inventory, ‘Forty-five Orange and Lemon trees in tubs’.

In celebration of this, our garden team continue the tradition each year by displaying various plants in the Garden house for visitors to see. Currently, we have our seasonal spring display on show which hosts a variation of colourful flowers including tulips, amaryllis and allium and other exotic-scented plants which bring together a stunning and captivating show revealing the beauty of blossom.

Mrs Child’s Flower Garden

Sarah Child lived at Osterley between 1763 and 1793 and was a passionate gardener, filling the space in front of the Garden House with fashionable and exotic plants, which have been faithfully recreated for visitors to enjoy.

The garden features a series of beds, radiating out from the Garden House with paths twisting and turning through them. The flower beds would have been planted with a tall plant, shrub or tree in the centre, with colourful flowers of lesser height around it.

Tudor walled garden

One of the most loved features at Osterley is the Tudor walled garden. This part of the garden is split into sections, with space for the garden team to grow a wide range of plants which are sold in the second-hand bookshop, and a cutting garden which supplies beautiful flowers throughout the year for the display in the house. The long border at the top of the garden is traditionally planted with shrubs and perennials for year-round interest.

The ornamental vegetable garden

Over the years the gardening team have turned a derelict patch of ground within the walled garden into an organic ornamental vegetable garden, and it's here that they experiment with interesting and unusual planting.

The vegetable garden is divided into four plots; one is given over to more traditional cropping, the second is mainly a pumpkin patch, and the last two plots are creative zones planted with a mix of brassicas, dahlias, antirrhinums, zinnias and amaranths.

Organic gardening

A commitment to organic gardening at Osterley Park and House has seen a growth in wildlife, from hedgehogs to birds. The garden team stopped using fungicides and insecticides a number of years ago and limits its use of weedkillers to a small number of paths around the estate.

The difference has been most obvious in the Great Meadow, where layers of biodiversity can now be seen, from the insects and small mammals to the larger birds of prey such as owls, kestrels and red kites which feed on them.
