Designer bouquets in Brooklyn: the stems, the season and the scale
Designer bouquets in Brooklyn are composed from whatever stems happen to be in that week's delivery: Ecuadorian and French roses, lisianthus, hydrangea, lilies, gerberas, Misty Bubbles roses and, in spring, hyacinth. The florist buys the flowers for one order only once it has been paid, so the real choice starts with what is in season and how large the gesture needs to be. The three questions below follow in that order: the stems, the scale, and how to brief the florist.
A hyacinth in spring, a hydrangea in July: the season in a Brooklyn piece
Hyacinth is a spring bulb flower, cut for only a few weeks before the bulb moves on to leaf and rest. Hydrangea is a summer cut flower in the northern hemisphere, its round heads fullest from June onward. Lily, gerbera and lisianthus are greenhouse-grown and available all year, which means a piece built around them works in January just as well as in August.
Roses hold the same year-round place. Ecuadorian roses, French roses and Misty Bubbles roses are all in the catalogue whatever the month, so a composed piece rarely has to wait on the calendar for its central flower. A mono bouquet of French roses counts as designer work too: French is a technique rather than a variety, and the florist turns the outer petals back by hand to open the bloom.
Peonies are not part of this section's everyday stock: on the north-east coast they are cut only from late May into early June. Outside that window, a peony piece is still possible by request in chat, where the florist builds it from scratch and sends a photo with the price before anything is paid. Brooklyn's peony section covers the rest of the peony calendar. For how any composed bouquet holds up at either end of the year, flowers in Brooklyn sets out the care.

When the gesture outgrows one bouquet: Giants and Premium Sets
A designer bouquet is a hand-tied composition built for one pair of hands and one vase. When the occasion calls for more than that, Brooklyn has two neighbouring sections built for scale: Designer Giants, where the same composed style is simply built larger, and Premium Sets, which pair flowers with other gifts for one delivery.
The designer section itself is not limited to bouquets carried in the hand. It also holds composed work set in a box, a flower box proper and a basket, and all three stand straight on a table or desk without a vase having to be found for them. That makes the choice less about the flowers and more about where the piece will actually live once it arrives: an office desk, a kitchen counter, a hallway table.
A designer bouquet is not counted by its stems the way a plain dozen is; the composition is judged as a whole. Where the recipient is Russian-speaking, the custom of giving an odd number of stems still applies, and that custom, with the reasoning behind it, is set out on the flowers in Brooklyn page.

A reference photo or a few words: designer bouquet delivery in Brooklyn
The brief for a composed piece can be as short as the occasion and a budget, sent in chat; the manager comes back with a few options, each with its own photo and price, before anything is charged. A reference photo works just as well: shown an example, the florist can point to similar work already made or compose a new piece along the same lines.
Before the courier leaves, a photo of the actual finished bouquet goes to the sender, and any change asked for at that point is made before dispatch, not after. If a particular flower is not available that day, the florist substitutes something close in colour and price, and the swap is visible in that same photo rather than discovered on arrival.
Most orders built this way are handed over on the day they are placed. The exact timing for a given piece is shown on its own page, and the zones it can reach are set out on the delivery page.
For a ready mix rather than a composed piece built from scratch, mixed bouquets are the shortcut. For a gesture too large for one vase, Designer Giants takes the same style and builds it bigger. For a peony specifically, the window to ask is late May into early June, before the Northeast's own crop is gone.
