Bouquets in Chicago: why the stems matter more than the count
Bouquets in Chicago are picked for their flowers, not for how many stems went into them. In the US, an odd or even count matters only on a single stem; nobody tallies stems once they are gathered into a hand-tied bunch. So the real choices here are which flowers make up the bouquet, what wrapping suits where it is going, and what size matches the person sending it.
French roses, lisianthus and peonies: what a Chicago bouquet holds
The Chicago catalogue includes roses in several forms: full-headed Ecuadorian stems, French roses, and white-and-pink mixes sit alongside a plainer rose paired with lisianthus. A French rose is not a variety but a florist's trick, the outer petals folded back by hand to open the flower. Hyacinths, hydrangea, lilies and gerberas round out the rest of the catalogue; lilies and gerberas are greenhouse flowers available all year. Peonies are the one flower with a real local season: Midwest growers cut them from late May into early June, and outside that window they travel in from further afield.

Kraft paper for the lakefront, a planter for the apartment
A bouquet meant to travel suits bouquets in kraft paper or a simple paper bag: a walk along the lake in Edgewater or Uptown, a graduation afternoon spent mostly on your feet. See Chicago's flower calendar and weather for how the season shapes a day like that outdoors. Bouquets in planters work the other way, suited to something that will stay at home or on a desk rather than travel anywhere.
Working from your own photo is its own route into a bouquet. Send the picture over chat, and before any payment the florist sends back a few similar arrangements with prices attached, then builds the bouquet to match.

From one sender or a whole office: sizing the bouquet
Once the stem count stops mattering, size follows the occasion and the person giving it. A compliment bouquet or a mini bouquet suits a quick thank-you, while a large bouquet or a giant one usually comes from a group signing one card together.
One local habit holds regardless of size: a funeral arrangement from coworkers or a club is sent large, straight to the funeral home, while a smaller one from a close friend goes to the family's house instead. A business bouquet follows a plainer version of the same logic, marking a colleague's or a partner's day without turning into an event of its own.
Every bouquet is put together only after the order is paid, and a photo goes to the sender before the courier leaves. Most orders reach the recipient the same day they are placed, and the exact timing for a given bouquet shows on its own page; bouquet delivery in Chicago covers the rest.
A first order into bouquets in Chicago is easiest with the end in mind. Compliment bouquets suit a short-and-sweet thank-you, and giant bouquets suit an office signing one card together. You can send a reference photo in chat and receive similar options with prices before payment.
