We're a team of expert florists with a passion for what we do. We believe everyone should experience the joys of arranging flowers, no matter how busy they are.



So, what's the deal with our Petals By Post?

It really couldn't be simpler. Simple arrangements are sent as fresh blooms, packed, protected and delivered to your doorstep. Full instructions, easy-to-follow tutorials and insights on how to create the perfect arrangement are included in the box.

Brilliant boxes

We think our boxes are bloomin’ brilliant.


Designing a box that is both pretty and practical was no easy task.  After exploring all sorts of weird and wonderful packages, we settled on our classic duck egg box.


It fits perfectly through most letterboxes and is both pretty and practical, keeping your flowers safe throughout their journey to you.

Our expertise in a box

The difference in quality is what stands us apart from other letterbox flower companies.

Our team have over 80 years of floristry experience between them, so from designing carefully crafted and customised boxes to selecting the highest quality stems, we know our stuff and want to make sure you get the best experience from our flowers.

Protecting your petals

When you first open your box, you may notice protective wraps and containers of conditioning water on some of the blooms. 

We created the conditioning tubes to protect your flowers in transit and to avoid the slight wilting you may receive from other suppliers.

Our florist choice contains a selection of roses, carnations, alstroemerias and lisianthus. Nestled in mixed foliage and fluffy white gypsophila and with full instructions from our professional florists on how to arrange them.

Its a flower delivery experience that's really hands on and completely different.
