Occasions in New York: Thanksgiving, spring peaks and anniversaries
Of all the occasions in New York, Thanksgiving is the one built around a family table, and it falls on the fourth Thursday of November, a date that moves every year. Every other occasion here works differently: a birthday or a wedding anniversary is set by the sender, not the calendar, and the address and the timing settle the rest.
Thanksgiving in New York: flowers for the fourth Thursday of November
Thanksgiving in New York falls on the fourth Thursday of November, so the exact day shifts from one year to the next. What stays constant is the table: a long family dinner around it.
A low basket suits that table better than a tall, wrapped bouquet. Its stems sit in soaked foam rather than a vase of water, so it stands on its own among the serving dishes, and nobody has to find room for a vase once the food arrives. The section keeps a Thanksgiving centrepiece sized for exactly that spot on the table.
Orders for a fixed date and time slot are accepted across the city. The earlier one goes in, the more slots stay open, right up to the day itself.

The New York dates when slots fill first: February and May
14 February and the second Sunday of May are peak days on the New York calendar. Volume on both runs several times higher than usual, and delivery windows widen to cope. Nobody promises a time down to the minute, so booking Valentine's Day flowers or Mother's Day flowers several days ahead is the safer choice.
Close to half the roses sold across the United States in a year move in the weeks around these two dates.
Mother's Day itself began in Grafton in 1908, when Anna Jarvis sent five hundred white carnations to a church service held for mothers. By the 1920s the custom had split the flower in two: a red carnation for a mother still living, a white one worn in her memory.
Administrative Professionals' Day falls on the Wednesday of the last full week of April and brings a smaller wave of orders. So does 25 December, alongside the Christmas holiday itself.
Wedding anniversaries, from the first year to the golden fiftieth
Naming a gift for a wedding anniversary began in German-speaking lands in the sixteenth century, where the twenty-fifth year earned silver and the fiftieth earned gold. English-speaking countries filled in the years between later, in the nineteenth century: a paper anniversary for the first year, wood for the fifth, tin for the tenth.
In 1937 an American jewellers' association turned the custom into a full list, naming a gift for every year to the twentieth and then every fifth year after it. The section follows that same calendar with wedding anniversary flowers, alongside plain anniversary bouquets and a set kept apart for the golden fiftieth, so the choice can match the year itself.
Where the evening runs to a restaurant table, the timing is worth a call to the venue first. A florist can time the arrangement to land with the dessert or the toast, rather than sit through the whole dinner unnoticed.

A new baby, a new key, an apology: personal reasons to send flowers
A handful of occasions here carry no date at all: the arrival of a baby, the trip home from the maternity ward, a christening, a housewarming, a thank-you or an apology. Nobody but the sender decides when one is due, which is why flowers for a new baby and the rest can be chosen without waiting for a calendar date.
The maternity ward is worth checking first. New York's larger hospital systems keep live flowers off several wards, including some maternity floors, so it helps to know which wards accept flowers before the bouquet sets off.
An apology or a quiet thank-you often travels without a name attached. The courier works from the recipient's name and address alone, and the card can carry a signature or stay blank, which is the idea behind anonymous flower delivery.
Every bouquet is put together after the order comes in, not pulled ready-made off a shelf, and the florist photographs it before the courier leaves. The card is free, most orders are delivered on the day they are placed, and the timing for each address shows on the bouquet's own card; delivery terms cover the rest.

A first order here can start with the date. Thanksgiving sets its own shortlist, and a wedding anniversary points straight to the gift that matches the year. Anything without a fixed date, from a birthday bouquet to a quiet apology, starts with the sender's own date and address.
