Letterbox flowers have quietly become one of the most popular ways to send flowers in the UK – and once you’ve tried them, it’s easy to see why. No waiting in, no “sorry we missed you” card, no bouquet left wilting on a doorstep. Here’s everything you need to know before you send some.
How they work
They’re fresh stems packed flat in a slim, sturdy box that’s designed to fit through a standard UK letterbox. The stems are usually sent in bud, wrapped with a water source or gel to keep them hydrated on the journey, along with flower food and simple care instructions.
Because they go through the door like post, the person you’re sending them to doesn’t need to be home. They simply come back to a lovely surprise on the mat.
Why people love them
- Nobody needs to be in. Ideal for busy friends, people who work long hours or anyone you’re surprising.
- They last well. Arriving in bud means they open in the vase over a few days, so you get more time out of them.
- They’re often better value. The slim packaging is cheaper to send than a big boxed bouquet, so the price is usually £20–£30.
- Arranging them is part of the fun. Lots of people enjoy the personal touch of putting the bouquet together themselves.
Are there any downsides?
They’re naturally a little smaller than a large hand-tied arrangement, and they don’t arrive ready to display – the recipient needs to put them in water. If you want instant wow for a milestone birthday or anniversary, a hand-tied bouquet delivered by courier might be the better choice.
It’s also worth knowing that a few doors – older or narrow letterboxes, or doors with a draught brush – may not take the box. In that case the courier will usually leave it in a safe place.

How to arrange and look after them
- Unbox them as soon as they arrive – don’t leave them sitting in the packaging.
- Fill a clean vase with cool water and add the flower food.
- Remove any leaves that would sit below the waterline.
- Trim a couple of centimetres off each stem at an angle, then arrange.
- Keep them somewhere cool, away from radiators, direct sun and the fruit bowl.
- Change the water and re-trim the stems every two or three days.
Don’t worry if they look a little sleepy on day one. Give them a few hours in water and they’ll perk up and start to open.
When should you send them?
Most sellers offer next-day delivery or let you pick a date. For birthdays and anniversaries, choose a specific date so they don’t turn up early. At Christmas, Mother’s Day and Valentine’s, order a few days ahead – cut-off times move earlier when everyone’s sending flowers. Our Christmas delivery dates page has this year’s last posting dates.
Quick answers
Do they come with a vase?
Usually not – a vase wouldn’t fit through the door. Check the listing, as a few sellers include a fold-out card vase.
How long do they last?
Looked after properly, a week or more is normal, and some stems like alstroemeria and carnations keep going for longer.
Can I add a message card?
Yes – most sellers let you add a free gift message when you order on Amazon.
Can I send them abroad?
The products we feature deliver within the UK only. For international flower delivery you’ll need a florist network that covers the destination country.
What does a bouquet of flowers symbolise?
It depends on the stems: red roses mean love, yellow means friendship and joy, white suggests sympathy or new beginnings, and pink says thanks or admiration. Whatever the colours, a bouquet shows someone you’re thinking of them.
