Sussex Gardens Landmark Events 2026
Record displays and landmark events make 2026 a standout year for Sussex gardens
From 1.4 million bulbs at Arundel Castle to landmark anniversaries at Nymans and Borde Hill, Sussex is set for its most spectacular year of gardens yet in 2026, positioning it as one of the UK’s must-visit destinations for garden lovers this year.
A packed calendar of floral festivals, heritage milestones and major planting displays is being matched by a growing focus on nature recovery, with gardens across Sussex playing an increasingly important role in restoring habitats and supporting biodiversity.
Jo Williams from Experience Sussex said: “2026 is a standout year for Sussex. Our gardens are looking better than ever and are part of a wider story of nature recovery and landscape care.
“From large-scale planting to gardens of the future, there is a real sense of renewal. For visitors, it is a chance to experience Sussex at its most vibrant and meaningful and discover a landscape being carefully nurtured for generations to come.”

Heritage and landmark moments
At Nymans, near Haywards Heath, a major exhibition celebrates the centenary of Winnie-the-Pooh, exploring how the Sussex landscape inspired the much-loved stories. The Grade II* listed garden is also home to rare plant collections and sweeping views across the Sussex Weald. The exhibition runs until 31 May 2026.
Borde Hill marks the 30th anniversary of its Rose Garden in June, showcasing hundreds of varieties at peak scent and colour. Created by five generations of the Stephenson Clarke family, the gardens remain one of Sussex’s most significant heritage landscapes.
