The second half of 2026 belongs to flower shows that trade spring’s delicate blossoms for something bolder: royal garden debuts on private estates, harvest celebrations that crown giant pumpkins, and parades built from millions of hand-placed dahlias. After a first half dominated by cherry blossoms in Taipei, tulips in Lisse, and the major spring showcases in Philadelphia and London, the late-year calendar offers a looser, more community-driven mix of events stretching from Norfolk to Colombia to the Netherlands.
Here is what remains on the global flower show circuit, and why each event matters.
RHS Sandringham Flower Show: A Royal Estate Welcomes the Public
The most significant change in British horticultural programming in decades is unfolding this summer. In 2024, the Royal Horticultural Society announced it would overhaul its show calendar: Hampton Court Palace Garden Festival became a biennial event, while Tatton Park shifted to triennial scheduling. In their place, the RHS launched a touring model, debuting at Wentworth Woodhouse in 2025 before expanding to two entirely new venues in 2026.
Badminton Estate in Gloucestershire hosted its show July 8–12. Now attention turns to Sandringham Estate in Norfolk, running July 22–26. The private country retreat of King Charles III and Queen Camilla provides the backdrop for the show’s centerpiece: the RHS Royal Legacy Garden, designed by Catherine MacDonald of Landform Consultants in direct consultation with the monarch.
Early descriptions reveal a garden built around fractal patterns and natural branching forms, with winding paths cutting through a biodiverse mix of trees and perennials. The planting incorporates many of the King’s preferred species and a bold personal color scheme. The garden pairs with a series of Long Borders mentored by Chelsea veteran Tom Hoblyn and multiple Show Gardens celebrating Norfolk’s landscapes and progressive horticultural practices.
Beyond headline attractions, the show offers standard RHS fare reimagined for a royal country setting: a Floral Marquee with more than 50 specialist growers, a Flower School creating elaborate tablescapes, a Summer Fruit and Vegetable Competition for junior growers, and a “Leaf Letters” activity where children write messages to the King and Queen on hand-picked leaves.
Meanwhile, Badminton’s earlier show delivered a standout in Jo Thompson’s Archers 75th Anniversary Garden, a scene-for-scene recreation of Bridge Farm from BBC Radio 4’s long-running rural drama, complete with welly boots sized for each generation of characters. Tom Stuart-Smith’s Julia Rausing Garden, at 2,400 square meters, became the largest show garden the RHS has ever staged.
Together, Badminton and Sandringham represent the real test of whether the RHS touring model can replicate the loyalty Hampton Court and Tatton Park built over decades. Early reviews suggest a promising start.
Feria de las Flores: Medellín’s Ten-Day Flower Festival
As Sandringham concludes, Colombia’s largest annual celebration begins. The Feria de las Flores, Medellín’s flagship festival, runs its 69th edition July 31 through August 9. The ten-day program includes concerts, classic car parades, farmers’ markets, and Antioquian folk music across more than 30 locations and 100 public events citywide.
Everything builds toward the festival’s closing spectacle: the Desfile de Silleteros on the final Sunday. Flower farmers from Santa Elena, a mountain community above the city, carry elaborate floral arrangements called silletas strapped to their backs. Some stand over three meters tall and weigh as much as 80 kilograms, built over months using dozens of flower varieties and depicting Colombian landscapes and cultural symbols.
This year’s parade includes more than 500 silleteros of all ages, with dedicated categories for children and participants with disabilities. They walk a roughly 2.4-kilometer route through the city center to Plaza Mayor, where the floral monuments remain on public display for several days afterward.
By most measures, this represents the single largest showcase of hand-carried floral craft anywhere in the world. Unlike RHS shows or Keukenhof, it descends directly from the region’s flower-growing economy rather than garden-design traditions, giving it a distinctly different texture.
Southport Flower Show: Britain’s Largest Independent Show at Peak Season
Late August in England belongs to Southport, which bills itself as the UK’s largest independent flower show. Running at Victoria Park since 1924, the event opens to everyone across all four days with no members-only previews, drawing more than 55,000 visitors.
The late-August timing is deliberate. It sits in the gap after summer planting and before autumn clear-up, meaning perennials and annuals reach their seasonal peak and the Grand Floral Marquee explodes with color. New for 2026 is “The Lakeside Reset,” a redesigned water-feature area intended as a calmer counterpoint to the busy showground.
Competitive classes for cut flowers, pot plants, and specialist grower exhibits are judged by midday each day, with ribbons displayed immediately. The Garden Theatre lineup opens with broadcaster and horticulturist Adam Frost, continuing Southport’s tradition of attracting serious gardening names alongside its family-day-out atmosphere.
Bloemencorso Zundert: The World’s Largest Flower Parade Returns
In the Netherlands, autumn opens with one of the most singular events on the global calendar. Bloemencorso Zundert, held in the small North Brabant town on the first weekend of September, centers entirely on a single flower: the dahlia.
Twenty neighborhood teams spend the entire year cultivating dahlia fields. Approximately eight million blooms are used in total, some six million grown locally in Zundert itself. During “Stick Week,” the final preparation period before the parade, volunteers attach the flowers by hand onto enormous steel-and-papier-mâché float structures reaching 19 meters long and 9 meters high.
The floats parade through town Sunday afternoon, judged by an independent jury for the year’s best design. Monday’s public exhibition day lets visitors approach close enough to appreciate the sheer density of flowers. From a distance, the most accomplished floats appear detailed enough that many visitors don’t immediately register the entire surface consists of living dahlias rather than paint or fabric.
Founded in 1936 and now recognized on the Netherlands’ national inventory of intangible cultural heritage, Zundert remains the largest flower parade anywhere in the world, built entirely by volunteers rather than professional exhibitors.
Malvern Autumn Show: Britain’s Biggest Harvest Celebration
The season proper closes with the Malvern Autumn Show, returning to Three Counties Showground in Worcestershire. Now in its 30th-plus edition, the event positions itself less as a flower show in the Chelsea mold and more as a full harvest festival.
Alongside RHS floral displays and more than 100 “Grow to Show” competitive classes for cut flowers, succulents, fruit, and vegetables, the show’s best-known fixture is the CANNA UK National Giant Vegetables Championship. Competitive growers chase Guinness World Records titles with marrows, giant green beans, super-sized sunflowers, and the show’s perennial headline act: enormous pumpkins.
The event serves as a fitting bookend to a flower-show year that, across every continent, returned to the same theme: gardens and growers responding to season, place, and community rather than working against them. Malvern’s giant vegetables and Zundert’s dahlia floats sit at one end of that spectrum, built from months of unglamorous cultivation. Sandringham’s royal borders and Southport’s peak-season marquees sit at the other.
Between them, they cover most of what a flower lover could want from an autumn.
Worth Watching For
Regional chrysanthemum and dahlia society shows continue through October and into November across the UK. Bishop Auckland’s long-running Late Chrysanthemum Show typically falls in early November.
As with all outdoor events on this scale, most remain weather-dependent. Given 2026’s volatility for UK growers—a wet, record-warm June following a deluge-heavy January—late-summer and autumn show reports may include as much discussion of irrigation and heat-stressed bedding plants as of the blooms themselves.
For the dedicated flower traveler, the lesson is clear: the best of the year’s calendar still lies ahead.
