10 Event Florist Tips Every Good Planner Should Know

Event florist — a role that often goes under the radar, yet anchors every memorable occasion you’ve attended.

Without one, even the most considered event can fall flat. Are you planning something and want a crash course from our London event florist team at Blooming Haus?

Today, we’re sharing the tips and principles we think every planner should know.

For a summer event, engaging the senses comes more naturally when you work with the colours, textures, and scents synonymous with the season. Whether or not guests are consciously aware of it, seasonal cues register — we are, after all, part of nature.

This doesn’t mean the flowers have to be predictable. A great event florist consistently challenges expectations and delivers the unexpected. It simply means the designs will feel harmonious, enhancing the experience rather than sitting apart from it.

Choosing seasonal blooms also means better value — and a reduced environmental footprint, as your event florist is far less likely to need to source from overseas. Local and seasonal flowers also hold up better: installations stay fresher for longer.

The best event florists are, at their core, designers. They’ve made colour, proportion, and composition their craft — and they understand that colour is one of the most powerful tools available, largely because of how it works on us psychologically.

Colours associated with luxury tend to be white, black, or red. Deep purples and greys create a moody, atmospheric quality. Our advice is to start with the intention of your event — what you want guests to feel — and let colour psychology guide your palette before you get into specific shades and combinations.

Of course, all of this must work within the client’s brief — their requirements, desires, or brand identity. And don’t overlook the venue. Rather than seeing its existing decor as a constraint on your colour choices, treat it as a starting point for how you can transform the space.

You’ll typically have a limited window to ensure flowers arrive fresh. Sourcing them within a reasonable distance from the venue is the most straightforward way to protect both quality and timing.

It’s also the more sustainable approach — shorter supply chains mean a lower carbon footprint and less reliance on air freight. At Blooming Haus, we believe in giving back as much as we take from the natural world. For every event flowers project we complete, we arrange for a tree to be planted in the client’s name.

One thing to keep in mind when sourcing locally: flexibility matters. If your first choice isn’t available from a nearby supplier, you’ll need a backup plan.

For smaller, more intimate events, we’ve recently added luxe vase arrangements to our online flower shop — with UK next-day delivery available.

When organising an event, be aware that certain flowers may carry special cultural significance for some attendees — something worth researching in advance to avoid inadvertent offence. It’s equally important to check whether allergies are likely to be a factor before finalising your floral choices.

There may be other audience considerations too. Is sustainability a priority for this crowd? In many sectors — particularly corporate — it’s now an expectation rather than a bonus, and your floral choices should reflect that. For example, are you avoiding materials like floral foam, which are harmful to the environment?

Flowers are sensitive to the elements — heat, humidity, rain, sudden drops in temperature all affect how long they look their best. This is a variable that needs to be built into your planning from the start.

For example, if you’re working in a summer marquee, humidity can be particularly damaging to delicate blooms like hydrangea. At Christmas, even a persistent draught can cause a poinsettia to deteriorate rapidly.

The basics to cover: keep flowers out of direct sunlight, away from heat sources such as radiators or open fires, and well-protected during cold-weather transportation.

Specialising in luxury floristry means knowing how to invest a budget wisely. The most effective approach is rarely the most extravagant — it’s the most considered.

When budgets are tight, a single statement installation almost always has more impact than decorations spread thinly across a space. Floral displays should complement the event and serve its purpose. The goal isn’t to fill every corner with flowers — it’s to tell a story that stays with guests long after the night ends.

Skilled event florists can do this at any budget level.

Your flower and food choices can clash in ways that aren’t immediately obvious. Heavily fragrant blooms can interfere with guests’ palates, diminishing their appreciation of the food being served.

If you want to use strongly scented flowers, position them in arrangements well away from where food is served.

Flowers are at their peak for a short window. Getting the timing right when creating floral designs for an event is therefore non-negotiable.

We source flowers as close to the occasion as possible, leaving enough lead time for construction. From there, we condition and hydrate each stem correctly to ensure they look their best at exactly the right moment.

Each variety opens and matures differently, so a thorough knowledge of your flowers — and prompt, careful treatment of them — is what separates a good result from a great one.

Thorough planning makes problems with event flowers less likely — but no amount of preparation puts you entirely in control of nature. A variety may be in short supply; a supplier may have a logistics issue on the day.

Having contingencies built into your plan prevents these moments from affecting the overall look and feel of the event. We monitor our supply chains closely so we can anticipate issues and respond before they become problems. We also keep extra stems on hand for every installation, so any imperfect flowers can be swapped out without disrupting the design.

Flowers don’t need to go to waste once an event ends. Many hosts of weddings and social occasions invite guests to take arrangements home with them — a simple gesture that extends the life of the flowers and adds a generous final touch to the evening.

It’s also worth reaching out to local organisations who would be glad to receive them. Shelters, nursing homes, and community groups can usually be found and contacted through social media, making this an easy addition to any post-event plan.

We hope these tips leave you feeling better equipped, whether you’re planning independently or working with a florist. Either way, these are the questions worth asking at every stage.

Our event florist team at Blooming Haus have worked on everything from the Vogue Forces for Change dinner [LINK NEEDED] to private, intimate gatherings. Challenging the expected is what we do — and we can work solo or as part of a wider event team to ensure our designs land exactly as intended.

For corporate events, our work often becomes a centrepiece of the client’s brand presence. The image above shows flowers we designed for Boden’s new clothing collection launch — bold, colourful, print-driven, and very much the point of the room.

We approach every event as a floral mise-en-scène: a way of giving the occasion a real sense of intention. The same applies to weddings, where the goal is to tell the couple’s story — as we did for Tara and Joel here.

If you have an upcoming event that needs event flowers, we’d love to be part of it.
