Bouquets in Boston: farm weeks, flown-in stems and choosing by colour
Bouquets in Boston follow Massachusetts farms through two short seasons: peonies from late May through June, then dahlias from mid-July to early October, peaking in September. For most of the rest of the year, bouquets are built from flown-in and greenhouse flowers, so the choice comes down to the recipient and the colour rather than the calendar.
Two short farm seasons, then flown-in stems all year
Bouquets in Boston can include genuinely local stems for a few weeks a year. Massachusetts growers cut peonies from late May through June, and that is the one stretch when the flower and the farm line up.
Dahlias follow from mid-July to early October, peaking in September, but that marks the farms' calendar rather than a promise that dahlias are available to order. For most of the other months, a bouquet here is built from flown-in flowers. Imports make up close to four-fifths of the cut flowers sold in the US, and Colombia supplies more than half of that, with Ecuador sending close to a quarter. Ecuadorian roses turn up alongside French roses, which is a finishing touch rather than a variety: the florist folds the outer petals back by hand.
Lilies, gerberas, chrysanthemums, lisianthus and alstroemeria are greenhouse flowers, so bouquets built around them don't depend on the month at all. Where a pastel, rounded bloom is wanted outside June, peony-shaped roses such as 11 Red French Roses or Peony Roses Bubbles No. 3 stand in, often English David Austin varieties or similar roses, grown for that cupped shape rather than cut from a farm.
What Boston weather does to a bouquet once it's indoors is explained on the flowers hub.

Romantic or not: a bouquet for a partner, a friend or a colleague
For a partner, the Romantic section is the obvious starting point. Victorian flower dictionaries read a red rose as passionate love, though there was never one agreed list of meanings, and a name like 11 Red French Roses leans into that without spelling it out.
For a colleague, American florist guides suggest steering away from romance: tulips, daisies, sunflowers and peonies come up again and again as choices that read as friendly rather than courting. Business Bouquets are put together with that line in mind, so sending one there doesn't need a second thought.
Office etiquette in the US also runs one way: gifts travel down, not up. A manager is better thanked with flowers from the whole team than from one person, while a gift to a close colleague is usually kept quiet rather than announced to the floor.
Chrysanthemums carry none of the mourning associations they have in France or Italy; here they read as a cheerful, everyday flower, fine for a desk or a thank-you. White lilies, roses and chrysanthemums together are the combination usually sent to a funeral home instead.
Bouquet delivery in Boston when the colour matters more than the flower
Bouquets by Colour suit a sender who knows the recipient's favourite palette but not which flower to ask for. Every bouquet is made to order, so if a particular bloom is out, the florist swaps in something close in shade and price, and that swap is visible on the photo taken before the courier leaves. A quick reply to that photo is enough to ask for a change before the bouquet goes out the door.
A photo of your own works the same way through Bouquet from Your Photo: send it across and the florist comes back with similar arrangements and their prices before any payment is taken, so there are no surprises later.
Bouquet delivery in Boston usually means a same-day handover: most orders are handed over on the day they are placed. The exact window for a given bouquet is shown on its own page rather than promised here; the delivery page covers that and the rest. A card is free with every order. Hotels and wards follow the handover rules of the place.

Choosing bouquets in Boston gets easier once you know where to start: peonies for the few weeks they're local, romantic bouquets for a partner, and bouquets by colour when the palette matters more than the name of the flower.
