Birthday in Miami: the rose, the hydrangea and a bouquet timed to the cake
For a birthday in Miami, the flowers often start at the airport: before 14 February, inspectors at Miami airport clear roses, carnations, pompon chrysanthemums, hydrangeas and baby's breath. Two of those, the rose and the hydrangea, also go into birthday bouquets in Miami. The choice really starts with a simpler question: one rose on its own, or a rose standing next to something else.
A rose that looks fuller than its bud: French and peony-shaped
A French rose is not a variety but a technique: the florist turns back the outer petals by hand, so a tight bud looks like a fuller, more open flower. The eleven French Roses bouquet is built this way, and it comes in red as well as the softer shades. Peony-shaped roses lean toward that same fullness naturally, since most of them are English varieties bred by David Austin. Colour still carries old associations worth knowing. Victorian flower dictionaries read a red rose as passion, a pink one as a softer kind of affection and a white one as purity. No single agreed list of meanings ever existed, and the meanings differ from book to book. The eleven White and Pink Roses bouquet keeps that gentler register, while Roses with Lisianthus pairs the rose with lisianthus. Whichever one is chosen, a rose in water holds for about a week, occasionally stretching to ten days with a fresh cut and clean water changed often.

Hydrangea off the MIA cargo flights, with lily or gerbera beside it
Hydrangea travels on the same cargo flights through MIA, and once it reaches the vase it drinks harder than most of what sits beside it. A hydrangea head takes in water through its petals as well as its stem, which is why a drooping one can usually be brought back: stand the whole head in cool water for an hour or two and it lifts again. A lily works on its own or next to a gerbera, but before you order, it's worth asking whether the birthday person keeps a cat. Every part of a lily, including the pollen and even the water left standing in the vase, is toxic to cats. Lily pollen leaves hard-to-shift stains on fabric. Once a lily opens, its anthers are usually removed so the pollen doesn't stain. Where a few kinds of flower together suit better, look at mixed bouquets.
Birthday flower delivery in Miami for a surprise nobody announces
Birthday flower delivery in Miami can arrive as a genuine surprise, because nobody calls the recipient ahead of time unless the sender asks for it. The one exception is a house or a gated property a courier cannot enter without ringing first; there, the knock on the door is the announcement. The order needs no address at all if a phone number is given instead. A photo of the finished bouquet reaches the sender's phone before the courier sets off, so there is a last look before anything is handed over. When the birthday is being celebrated at a restaurant, the delivery time is arranged with the manager and timed to land with the dessert or the toast rather than at a fixed hour chosen in advance. A basket stands on the table with no vase needed at all, and flowers in a box work the same way for a car ride or a desk that has nowhere to put water. Delivery runs across the city's delivery zones, and most orders are delivered on the day they are placed.

Cake, card and balloons alongside the birthday bouquet
A bento cake ordered with the bouquet follows USDA's rule for a cream cake: no more than two hours at room temperature, and no more than one once the air passes 32 °C (90 °F). Summer afternoons often reach that mark in the Miami heat, so put the bento cake somewhere cold as soon as it arrives. A card written in your own words costs nothing extra and travels tucked in with the flowers. Balloons last differently: a latex one stays afloat for roughly half a day and less once the heat reaches it, while a foil balloon can hold its lift for several days. Gifts to go with the bouquet can be added to the same order.
If you're not sure where to start, look at the roses, French or peony-shaped, or a flower basket if there's no vase at the address.
