Birthday in Barcelona: a bouquet the florist buys for your order
For a birthday in Barcelona, the cut flowers all come from one place: Mercabarna-flor, the city's wholesale flower market in Sant Boi, trading since 1984 and rebuilt in 2008 after a fire in 2001. Private shoppers can't walk in and buy there, so a birthday bouquet reaches you through a florist, and at JFLOO that florist buys the stems for your order only after it's paid. From there, the choice is yours: which flower, which colour, and where it needs to arrive.
A rose that isn't the April one: French-opened or white with pink
On 23 April, Sant Jordi's day, Catalonia's old custom paired a red rose, a wheat stalk and a ribbon in the colours of the Catalan flag. In return came a book, and today either gift goes either way. That custom has nothing to do with a birthday, but close to the date a red rose in Barcelona can still read as the Sant Jordi gesture rather than a birthday one.
Where that's a concern, 11 White and Pink Roses is a plain alternative: the colour sidesteps the April association without needing an occasion of its own to explain it.
For the red rose itself, there's 11 Red French Roses. French-opened isn't a variety, it's a florist's technique: florists bend the outer petals back by hand, so the rose reads as open rather than tightly closed. Roses in the birthday selection come bunched in elevens, with other colours available outside this list for anyone after something different.

Lilies, gerberas and hydrangea for a birthday that skips the rose
Lilies, gerberas and lisianthus are greenhouse flowers, cut all year round, so a birthday in Barcelona in January has the same choice as one in July. A bouquet pairing lily with gerbera suits anyone who finds the rose too predictable, and a hydrangea bouquet brings fuller heads in a softer colour range. A hydrangea head needs more water than most cut flowers, and it absorbs moisture through the petals, not just the stem. Once it's home, it goes straight into a vase rather than waiting dry on a table.
One flower to leave off the list: in Spain, chrysanthemums go to the cemetery on 1 November, for Tots Sants, and aren't given to the living.
Birthday flower delivery in Barcelona to a terrace table or a door
For dinner on a terrace or a table at home, a basket stands on its own, no vase needed. The stems sit in wet floral foam, watered daily in a thin stream across the whole surface rather than poured from one side.
At a restaurant, the courier coordinates arrival with the venue in advance, timing the delivery to dessert or the toast instead of the start of the meal. A card with your own words is free with the order, and a bento cake, balloons or other sweets can go into the same basket among gifts to go with the bouquet.
Most orders are delivered the same day; the exact timing is shown on the bouquet page. A photo of the finished flowers goes out before the courier leaves, and delivery pricing by zone is set out on the delivery terms page. Hotels, offices and orders placed from abroad work the same way, covered under hotels, offices and orders from abroad.

That's the shortcut for a birthday in Barcelona: start with the roses, pick flowers in a box for a table setting, and add the cake and the card while you're at it.
