Graduation in San Francisco: peony-shaped roses and the colours to choose
Peony-shaped roses in lavender are among the flowers for graduation in San Francisco: a rose that passes for a peony, most often an English David Austin variety or one bred close to it. Picking between them comes down to what the graduate can carry in one hand, what colour won't trouble grandparents who keep Chinese custom, and what is still on the table once the gown comes off.
Lavender for the graduate: peony-shaped, spray or a small bouquet
A peony-shaped rose opens into a full, many-petalled head, rounder than an ordinary rose and closer in shape to the flower it is named after. Lavender is the colour this occasion leans on, so a spray rose and a peony-shaped one in the same shade look like one gift.
For a graduate who needs a free hand for photographs, diplomas and handshakes, 11 Lavender Spray Roses or a small bouquet is easier to hold than a large armful. Where the whole family wants to mark the day together, twenty-five stems reads as a bigger gesture without changing the colour. The choice comes down to a simple question: ask whether the graduate will have a hand free when the flowers arrive, or will be holding a phone, a cap or a diploma folder.
The stems and the exact shade are visible in a photograph the florist sends before the courier sets off. A buyer unsure about a lighter or deeper lavender can ask for a change before the bouquet leaves.

In Chinese tradition, white flowers and yellow chrysanthemums are tied to mourning and are not given as gifts. In the United States a chrysanthemum is usually a cheerful, everyday flower; in China it stands for longevity rather than grief, provided the colour is right.
So a mixed bouquet built around chrysanthemums and lilies works for most American families. For a Chinese-American family that keeps Chinese custom, the colour is worth checking before anything else. A bouquet of white roses, fine for many recipients, is one to set aside here; lavender, peach or pink reads as a safer choice for grandparents who hold to the older rules.
Where the right shade isn't obvious from a description alone, describe it in the chat: a manager sends options with photos and prices before payment.
Graduation flower delivery in San Francisco after the gowns come off
Once the ceremony is over, a bouquet left on the kitchen table has longer to prove itself than one carried across a stage. The 51 Jumilia in Airy Wrapping suits that role: each bud opens to up to seven centimetres, white at the base and pink at the edge. With good care it lasts up to two weeks in a vase.
Chrysanthemums run a similar course, lasting two to three weeks, though their leaves usually turn before the flowers do and are worth stripping off as they go. A box of roses, a basket or a floral handbag all stand on a table without extra help. A basket in particular needs no vase at all, since its stems already sit in soaked foam. Lilies are worth leaving out of a home with a cat, and once a lily opens the anthers are usually removed to stop the pollen marking tablecloths or sleeves.
In the centre, delivery is free, and most orders go out the same day they are placed. For a dinner at a restaurant, the time is agreed with the manager there and the flowers arrive at the right moment, with dessert or a toast; see the delivery terms. San Francisco's weather and ordering flowers from outside the city are covered in our guide to flowers in San Francisco.

Start with the format, then settle the colour: mono bouquets suit a single flower kept simple, roses give the widest choice of shade, flowers in boxes stand on a table without help, and flower baskets need no vase at home.
