A First Timers Guide to RHS Chelsea Flower Show

“Chelsea Flower Show is the Glastonbury of people who wear linen,” said one celebrity to another about Chelsea Flower Show, this May.

It’s true! It’s all about petals, Pimms and people watching. Crowded, chaotic, colorful, wildly British, and fueled by horticultural myth and legend.

As a first timer this May, here’s a decoder follow-up for fellow newbies contemplating attending Chelsea Flower Show some day. And if you can’t imagine you’ll make a visit yourself in person, then I hope my words and pictures transport you there on the page!

Securing tickets to the RHS Chelsea Flower Show is notoriously difficult. The most sought-after days sell out within hours of release, often months in advance. The first three days are reserved exclusively for Royal Horticultural Society members, royalty, and celebrities.

I was incredibly fortunate and grateful to be invited by dear friends to join them while I was in the UK visiting family — not on the same day as King Charles and entourage, but soon after. The timing could not have been more perfect. It felt like a dream come true — something I had never quite imagined I would manage to make happen for myself given that I spend most of my year pottering around my own back yard, some 5,350 miles away in Northern California.

Approximately 157,000 people attend the show over its five-day run, with numbers capped by the capacity of the 11-acre showground. As a result, tickets are among the most sought-after on the British social calendar. Once inside its tree-lined cocoon, it’s like stepping into an entiterly different world in contrast to the busy streets of the King’s Road and Chelsea’s posh neighborhoods.

First things first: if you hope to secure a ticket to next year’s show, there are a few strategies worth knowing.

The best option is to join the RHS, which gives you access to the presale opening in October. If that doesn’t work out, keep a close eye on official ticketing partner AXS, where returned tickets are often released in the lead-up to the event.

If you think you may be in London next May, 2027 these are the key dates to know:

• Monday, May 17: Press Preview & Judging Day (closed to the public)

• Tuesday, May 18: Open exclusively to RHS members

• Wednesday, May 19 – Friday, May 21: Open to RHS members and the general public, with evening entry available from 5:30 p.m.

• Saturday, May 22: Final day, closing early at 5:30 p.m., and famous for the much-anticipated plant sell-off

For guaranteed — albeit more expensive — access, hospitality partners such as Seat Unique offer premium ticket packages that include perks like afternoon tea and exclusive lounge access. Specialist tour operators, including Garden Tours, also often have allocated tickets available.

Britain’s chicest horticultural spectacle calls for espadrilles and colorful sneakers instead of wellington boots. It is sprawling and slightly exhausting by the end of the day, with a lot more champagne bars and less bucket hats than a music festival. There is no dress code, but it certainly appears to be the more eccentric the better! And I do love to see a man in a crsip linen, summer suit.

I was happy to witness a mad, British fashion parade of zany floral prints, at every turn. And I saw everything from serious horticulturists with measuring tools to groups of visitors treating it like a summer social event. Both are correct ways to attend.

There are a range of bookable catering options at the RHS Chelsea Flower Show, from relaxed breakfasts to elegant four-course lunches showcasing the best of British produce. Throughout the day, visitors can enjoy everything from all-day tapas by leading London chefs to afternoon teas ranging from quirky to traditional. Across the showground, there is also a wide variety of hot and cold food and drink outlets, including some of London’s most exciting street food vendors.

Vegan, vegetarian, and non gluten-containing options are available both at the pre-bookable restaurants and the casual food outlets. Visitors are also welcome to bring a picnic — something I would absolutely recommend. By lunchtime, many of the food areas were extremely crowded, with several popular items already sold out. We noticed quite a few people happily eating sandwiches and snacks they had brought from home, and if I return, I would definitely do the same.

One thing I would also pack next time is a small portable fold-out stool. Seating throughout the grounds was surprisingly limited, and after hours of walking and standing, having somewhere to perch would have made a huge difference.

We didn’t arrive until around 10:15 a.m., as we were travelling in by different trains. In hindsight, I would absolutely aim to get there earlier next time, if possible. Gates open at 8 a.m for early birds in the area. The showgrounds fill quickly, and arriving sooner would have meant slightly smaller crowds, better opportunities to photograph the gardens, though we managed to successfully pace ourselves well and with patience, we saw pretty much everything, at least from the sidelines in the busier areas of the Main Avenue.

Overall Best in Show (Show Garden) this year: The Campaign to Protect Rural England Garden: ‘On the Edge’ — pictured below. It was designed by legendary designer Sarah Eberle as a naturalistic garden featuring a massive wooden carving of Mother Nature (Gaia), still water pools, and wildflowers.

Dress for the elements. The day we attended was overcast with intermittent drizzle, although later in the week London was hit by an intense multi-day heatwave — a reminder of just how unpredictable the weather can be in the UK in May. Layers are essential, along with a lightweight waterproof jacket. I would avoid umbrellas if possible, as they quickly become cumbersome in the dense crowds.

Comfortable flat shoes and sunscreen are also a must, as you will spend hours walking the grounds. Stay hydrated with a refillable water bottle, and if you suffer from asthma or allergies, be prepared for the infamous “Chelsea Cough.” While it may seem surprising at a flower show, the coughing and sneezing are often triggered less by the blooms themselves and more by the London Plane trees that surround the showgrounds. In spring, these trees shed microscopic stiff hairs from their bark and leaves, which drift through the air and can irritate the throat and nasal passages.

Fully charge your phone before arrival as photo opportunities abound at every turn. I almost ran out of juice and was envious of my friend’s portable charger she had stashed in her backpack. It didn’t fit my phone so I made a note to self to carry one in future. Especially as my train ticket was on my phone.

Download the flower show app before you arrive — it’s invaluable for accessing up-to-date maps, the plant directory, and exhibitor information throughout the day. It’s also wise to choose a designated meeting spot with your group in case you become separated. With crowds this large, it happens surprisingly easily, and mobile phone service can be unreliable across the grounds.

Design inspiration abounds. I especially enjoyed the porches, which provided a fantastic range of compact garden spaces for people with limited outdoor living room.

Good thing I was traveling back to the States the week after attending, as I would’ve been tempted to purchase all kinds of home and garden items from the many booths selling gorgeous curtains, planters, seeds, fountains, books if I still lived in the UK.

Country Life magazine staged one of the most enticing booths, drawing me in to peruse its bookshelf of classic tones for garden enthusiasts.

At the heart of the Chelsea Flower Show stands the Great Pavilion, the event’s vast centerpiece and, for many visitors, its greatest attraction. Covering nearly three acres (approximately 12,000 square metres), this enormous marquee is home to spectacular floral displays, specialist nurseries, educational exhibits, and the show’s iconic central monument.

We headed in on arrival to avoid later crowds. The school garden pictured above was a bright, visual reminder of the importance of connecting kids to nature.

Inside, visitors can explore exhibits from hundreds of growers and nurseries from around the world, all competing for coveted RHS medals. One of the most anticipated displays each year is the magnificent David Austin Roses exhibit, which occupies the largest single space within the pavilion and is renowned for its breathtaking abundance of blooms.

The Great Pavilion is also where many of the year’s most exciting plant introductions make their debut. New varieties are unveiled here, with the best competing for the prestigious RHS Chelsea Plant of the Year award. In recent years, the Houseplant Studios have become a popular addition, showcasing innovative ideas for indoor gardening and stylish plant-filled interiors.

If you’re short on time, make the Great Pavilion a priority. It offers an extraordinary concentration of horticultural expertise, inspiration, and sheer floral beauty all under one roof. For those wanting to delve deeper, the RHS publishes a full list of exhibitors, medal winners, and award recipients following the show.

Serious plant buyers or collectors come back later in the week when plants are sold off or restocked differently.

I expected the pale peach David Beckham rose to smell like Armani, but its subtle scent surprised me. It is truly as delicate as his finest footwork on the pitch!

I will always treasure the day spent at RHS Chelsea Flower Show and quality time spent in the company of my generous friends.

Given the chance, I would jump at a return visit some day.

Travel by tube or train

Tube
Sloane Square tube station (on the District and Circle Lines) is a 10-minute walk from the showground.

I ran into a huge crush of people on the platform at Sloane Square after the event. A nice woman from Harrogate befriended me and suggested we jump on any train we could squeeze into and offboard at a bigger station in order to both make our way to King’s Cross via another line. That worked.

For further information on tube travel, visit theTransport for London website.
Plan ahead, check before you travel.

Train
London Victoria is the closest train station to the show. For information on rail services, visit the National Rail website.
