Autumn is arguably the best time to visit a British garden. The summer crowds thin out, the light turns golden, and trees that look ordinary in July put on a short, dramatic show. A new round-up from The Independent highlights 12 gardens across the UK where the season's reds, oranges and yellows are at their most striking — and a few have opening dates or events worth planning around.

In Yorkshire, the Castle Howard Arboretum spans 120 acres of woodland with more than 7,000 trees, peaking from October into early November. As well as bronze oaks and fiery Japanese maples, it runs one of the UK's most successful red squirrel conservation programmes, plus fungi foraging walks and an artists' fair this season. In Wiltshire, Stourhead is often compared to New England in the fall: flame-red swamp cypresses and golden tulip trees frame the famous lake and classical temples. Photographers can book First Light early-morning sessions on October 23, 27 and 31 for £12.

Kent pulls its weight too. Bedgebury National Pinetum and Forest covers 350 acres with over 12,000 specimen trees — including giant redwoods — and Marshal's Lake ringed by rusty swamp cypress each autumn; it opens for the National Garden Scheme on Tuesday October 20. Nearby Lullingstone Castle's World Garden offers something stranger: curry-scented vindaloo shrubs, fragrant barbed wire bush from Argentina, and salvias still flowering into autumn.

Further north, RHS Garden Bridgewater in Salford has just unveiled the Yangzhou Scholars' Garden, the centrepiece of the largest classical Chinese garden in Europe. Coverwood Lakes in Surrey (NGS open day Sunday October 18) combines a 14-acre garden with four lakes and a working farm of Hereford cattle. Mount Stewart in County Down benefits from a mild climate that stretches its display of Japanese maples and sweetgums deep into the season, while Bodnant Garden in Conwy pairs crimson and amber foliage with the Carneddau mountains as a backdrop. In the Scottish Borders, Dawyck Botanic Garden — one of four regional gardens of the Royal Botanic Garden Edinburgh — adds autumn crocuses and fungi to its 65-acre arboretum.

Rounding out the list: Bluebell Arboretum in South Derbyshire with its 70-plus Japanese maples, RHS Garden Wisley in Surrey (watch for the short-lived 'Wisley Bonfire' tupelo in October) and Sheffield Park in East Sussex, where katsura trees turn pale yellow and pink and smell sweetly of caramel.

Why it matters: most of these displays last just a few weeks, and several gardens only open for the National Garden Scheme on specific October dates. If you want peak colour, aim for mid-to-late October, book timed events like Stourhead's dawn sessions early, and check katsura and maple varieties if scent and red foliage are your priority.
