NORFOLK, England \u2014 After a spring dominated by cherry blossoms in Taipei, tulips in the Netherlands and grand showcases in Philadelphia and London, the second half of 2026 delivers a looser, more varied lineup: royal debuts, harvest festivals, giant vegetables and floats built entirely from dahlias. From the RHS\u2019s first-ever show on a royal estate in Norfolk to Colombia\u2019s ten-day flower festival and the world\u2019s largest flower parade in the Netherlands, here is what remains on the global flower calendar and what each event offers.<\/p>\n
The biggest structural shift in British horticulture in years takes full effect this July. The Royal Horticultural Society, after announcing in 2024 that it would reduce the frequency of its Hampton Court and Tatton Park shows, launched a touring model with new venues. Following a successful debut at Badminton Estate in Gloucestershire earlier this month, the RHS opens its gates at Sandringham Estate in Norfolk from July 22 to 26.<\/p>\n
Sandringham is the private country retreat of King Charles III and Queen Camilla. The show\u2019s centerpiece, the RHS Royal Legacy Garden<\/strong>, was designed by Catherine MacDonald of Landform Consultants in direct consultation with the monarch. Early previews describe a garden built around natural fractals and branching patterns, with winding paths through a biodiverse mix of trees and perennials, incorporating many of the King\u2019s favorite species and a bold personal color scheme. The garden is paired with Long Borders mentored by Chelsea veteran Tom Hoblyn and a series of Show Gardens celebrating Norfolk\u2019s landscapes.<\/p>\n Beyond the headline garden, the show features a Floral Marquee with more than 50 specialist growers, a Flower School, a Summer Fruit and Vegetable Competition for junior growers, and a \u201cLeaf Letters\u201d activity where children write messages to the royal couple on hand-chosen leaves. The earlier Badminton show, held July 8\u201312, included Jo Thompson\u2019s Archers 75th Anniversary Garden \u2014 a scene-for-scene recreation of the fictional Bridge Farm from BBC Radio 4\u2019s long-running rural drama \u2014 and Tom Stuart-Smith\u2019s Julia Rausing Garden, at 2,400 square meters reportedly the largest show garden the RHS has ever staged.<\/p>\n As Sandringham concludes, Colombia\u2019s biggest annual flower festival begins. The Feria de las Flores<\/strong> in Medell\u00edn runs its 69th edition from July 31 through August 9, featuring concerts, classic car parades, farmers\u2019 markets and Antioquian folk music across more than 30 locations and over 100 public events.<\/p>\n The festival builds toward its closing set piece: the Desfile de Silleteros<\/strong> on the final Sunday. Flower farmers from the mountain community of Santa Elena carry elaborate floral arrangements called silletas strapped to their backs \u2014 some standing over three meters tall and weighing up to 80 kilograms. This year\u2019s parade will include more than 500 silleteros of all ages, with dedicated categories for children and participants with disabilities, walking a 2.4-kilometer route to Plaza Mayor, where the floral monuments remain on display for days. It is the largest hand-carried floral craft showcase in the world, rooted in the region\u2019s flower-growing economy.<\/p>\n Back in England, late August belongs to Southport Flower Show<\/strong>, the UK\u2019s largest independent show, running since 1924 at Victoria Park. Unlike RHS events, there are no members-only preview days \u2014 the show opens to everyone across all four days, drawing more than 55,000 visitors.<\/p>\n The late-August timing is deliberate: perennials and annuals are at their seasonal peak, making the Grand Floral Marquee especially vibrant. New for 2026 is \u201cThe Lakeside Reset,\u201d a redesigned water-feature area offering a calmer counterpoint. Competitive classes \u2014 cut flowers, pot plants, specialist exhibits \u2014 are judged by midday each day, with ribbons displayed immediately. The Garden Theatre lineup opens with broadcaster and horticulturist Adam Frost.<\/p>\n On the first weekend of September, the small Dutch town of Zundert hosts Bloemencorso Zundert<\/strong>, a parade built entirely around the dahlia. Twenty neighborhood teams spend the year cultivating dahlia fields \u2014 roughly eight million blooms are used, six million grown locally. In the final \u201cStick Week\u201d before the parade, volunteers attach flowers by hand onto enormous steel-and-papier-m\u00e2ch\u00e9 floats that can reach 19 meters long and 9 meters high.<\/p>\n The floats parade Sunday afternoon, judged by an independent jury, with a public exhibition day Monday allowing close inspection. From a distance, the most accomplished floats appear painted \u2014 the surface is entirely living dahlias. Founded in 1936 and recognized on the Netherlands\u2019 national inventory of intangible cultural heritage, it remains the world\u2019s largest flower parade, run entirely by volunteers.<\/p>\n Closing the season, the Malvern Autumn Show<\/strong> returns to Three Counties Showground in Worcestershire from September 25 to 27, positioning itself as a full harvest festival. Alongside RHS floral displays and more than 100 \u201cGrow to Show\u201d competitive classes for cut flowers, succulents, fruit and vegetables, the show\u2019s best-known fixture is the CANNA UK National Giant Vegetables Championship<\/strong>, where growers chase Guinness World Records with marrows, giant green beans, super-sized sunflowers and enormous pumpkins.<\/p>\n Regional chrysanthemum and dahlia society shows run through October and into November across the UK, including Bishop Auckland\u2019s Late Chrysanthemum Show in early November. As with all outdoor events, weather remains a factor. Given 2026\u2019s volatile conditions \u2014 a wet, record-warm June following a deluge-heavy January \u2014 late-summer and autumn show reports may include as much discussion of irrigation and heat-stressed bedding plants as of the blooms themselves.<\/p>\nFeria de las Flores: Medell\u00edn\u2019s Ten-Day Celebration<\/h2>\n
