No matter the season, Gloucestershire is the place to see exemplary gardens, urges Kathryn Bradley-Hole

The band of limestone that runs in a diagonal flash, crossing England from Dorset in the south-west to Lincolnshire in the north-east, has special meaning in the region of the Cotswolds.

Here, more than in any other area, there is an astonishing richness in gardens, made more beautiful by the honey-grey warmth of the handsome stone houses, picturesque villages and their dry-laid traditional boundary walls. Bright, evergreen box (Buxus sempervirens) and sombre, dark green yew thrive on the free-draining slopes of these hills and, for centuries, have been the plants of choice for creating decorative hedges and quirky topiary, seen in churchyards, and cottage front gardens as well as the grounds of manor houses.

They also provide an ideal plain-green framework within which the inventive gardener can grow a huge range of flora. My suggestions demonstrate a broad variation of styles of garden, yet all display aspects of the Cotswold vernacular and are open regularly across a range of seasons.

However, the region is so rich in good gardens that it’s essential to have in the car (or as an app on one’s smartphone) the National Gardens Scheme’s annual Yellow Book. This indispensible directory is the gateway to another 150-plus fine gardens in Gloucestershire and Oxfordshire, which open on selected days only, for charity (frequently on Sundays) and across all seasons (alternatively, visit www.ngs.org.uk).

Painswick Rococo Garden, Painswick
Bishop Pococke, a visitor to Painswick in 1757, noted: ‘The garden is on an hanging ground from the house in a vale, and on rising ground on the other side and at the end; all are cut into walks through wood and adorn’d with water and buildings, and in one part is the kitchen garden.’ Magnificent restoration over the past three decades has faithfully revived its early-18th-century ambience. A place steeped in atmosphere where you can stroll for hours.

Cerney House, North Cerney, Cirencester
This exuberant and richly planted gem is hidden away in a wooded valley. The creation of a mother-and-daughter team (with some part-time helpers), it includes lawns, a wildflower meadow, mature beech woods, a park and, of greatest interest to the plantsman, a walled Victorian garden. The latter features many roses and herbaceous plants through the summer, but spring is celebrated with thousands of tulips. Late-winter’s snowdrops are also a feature. Visitors enjoy Cerney’s laissez-faire ambience, a world apart from the region’s more ‘corporate’ horticultural hotspots.

Sudeley Castle, Winchcombe
A place that oozes history; it was Crown property during the Wars of the Roses and, after the death of Henry VIII, was given to Thomas Seymour, who married Henry’s widow, Katherine Parr. Elizabeth I was entertained here in the 1590s and Charles I stayed at the castle during the Civil War. A Victorian take on Tudor design then inspired the garden’s 19th-century renovation, with further enhancements in recent decades. There are about a dozen separate areas, including mighty yew enclosures and hundreds of roses, as well as romantic plantings among the medieval ruins.

Sezincote House, Moreton-in-Marsh
Set in beautiful undulating parkland among picturesque trees, the onion-domed ‘Mogul palace’ of Sezincote uses the local stone in unique fashion. Three Cockerell brothers are connected to both this property and the British East India Company and it was architect Samuel Pepys Cockerell who created the house for his brother, Charles.

The gardens contain plenty of Oriental references and ornaments and atmospheric lower gardens of pools and streams. The latter, planted with advice from Graham Stuart Thomas in the mid 20th century, continue to show how to do successful waterside planting with luxuriant perennials.
