Mother's Day in Paris: peonies in season and a bouquet for her table
Mother's Day in Paris lands on the last Sunday of May, or the first Sunday of June if that Sunday happens to be Pentecost, and French peony growers are cutting right through those weeks. In Belgium and Switzerland the date moves earlier, to the second Sunday of May, worth knowing if the order is crossing a border. What's left to decide is the flower and the shape it arrives in: a box ready for her table, or a bouquet for the vase she already owns.
Peonies in their French weeks, with roses and lilies beside them
French growers cut peonies from late April into June, a stretch of weeks the Fête des mères always falls inside. A peony bought for the day is therefore in season, not an exception to it. Peonies sold at what florists call the marshmallow stage, the bud still soft and barely cracked, open within a day or two in warm water and good light. In the vase they hold for five to seven days, so a bud closed on the morning it's delivered is usually open by the time she sits down with it.
Lilies make the safer choice for anyone ordering outside those weeks, or for a daughter who simply prefers them. Grown under glass, they are cut all year round, so the pairing doesn't depend on the calendar the way a peony does. Roses with Lisianthus or White Roses in Designer Wrapping both bring roses into the arrangement instead. In flower dictionaries, a pink rose stands for a softer affection than a red one.
One flower to leave out of a Mother's Day order is the chrysanthemum. In Paris it belongs to Toussaint, the first of November, when French families carry it to the cemetery rather than give it as a gift. French flower customs explain why it rarely turns up in a spring bouquet at all.

A hat box for her table or a bouquet for her own vase
A hat box needs nothing done to it: it sits on the table exactly as the courier hands it over. Designer Box No. 1 is built that way, and so is any flowers in boxes arrangement in the same format. A hand-tied bouquet wrapped in paper suits a mother who already keeps a favourite vase and would rather arrange the stems herself once she's home.
Lilies in a tall vase ask for one small piece of care. Once the flower opens, the anthers are best removed before the pollen sheds, because it stains fabric in a way that's hard to wash out.
The card that comes with either format is free, written in your own words rather than a set phrase. A foil balloon, a box of sweets or a vase itself can be added at checkout alongside the flowers. A foil balloon holds its helium for several days, while a latex one lasts roughly half a day: worth weighing if the gift needs to last through the whole visit. Gifts to go with the bouquet cover both options.

Mother's Day flower delivery in Paris, booked before the rush
Mother's Day in Paris sits alongside Valentine's Day and 8 March as one of the days when order numbers climb well above an ordinary Sunday, delivery windows widen and nobody promises an exact minute. Booking the date a few days ahead, rather than waiting for the morning itself, leaves more of those windows open. The earlier the order goes in, the wider the choice of slot.
The finished bouquet is photographed before the courier sets off, and there's still time to ask for a change before then. Zones and the areas they cover are listed on the delivery page, and the timing for a particular bouquet shows on its own product page rather than here. Ordering from abroad, or holding nothing but her mobile number, works the same way it does for anyone else sending flowers to Paris.
If she loves peonies, start there while the season holds; if she prefers something other than peonies, a box of roses or lilies works just as well. The card is where the order turns personal, so leave the set phrases aside and write it yourself.
