UK Mother's Day — properly Mothering Sunday — falls in March, not May. Worth stating plainly, because a meaningful share of Mother's Day search traffic every year is people working from the American date by mistake.
Where the date actually comes from
Mothering Sunday predates the American Mother's Day by centuries and has a different origin — a day when people historically returned to their "mother church," the main church of their home parish, often bringing flowers along the way. It's tied to Lent, which is why the date moves each year rather than sitting on a fixed calendar day.
Choosing for the actual relationship
"Mother" covers a wide range of relationships, and the flowers should follow the relationship rather than a generic Mother's Day template. A softer, more classic arrangement suits a traditional relationship with an older mother; something bolder and more design-forward suits someone whose taste runs that way regardless of her age. If you're choosing for a mother figure who isn't your biological mother — a stepmother, mother-in-law, or someone who filled that role — the same principle applies more, not less: choose for her, not for the category.
Palette that works broadly
Soft pink, white and neutral tones are the safest broad choice when you don't know a specific preference — they read as considered rather than generic, and they suit most homes and most tastes. Faerie sits in soft coral and blush, gentle without being plain; Roshi is a simpler, more understated pink option at a lower price point; Laurent is the structural white choice if her taste runs cleaner rather than softer.
When to order
Mother's Day is the UK's second-highest-demand day for florists after Valentine's Day, and it falls on a Sunday every year — which compresses delivery into a single day rather than spreading it across a week the way some occasions do. Order in the days before rather than assuming Sunday availability; same-day slots on the day itself are the first to fill.
The Florist Choice is a considered option if you'd rather trust what's genuinely in season than commit to a specific design in advance.
Same-day delivery across London for orders placed by 4pm. Next-day nationwide for orders by 5pm.
