Mono bouquets in Mumbai: one flower at a time, as in a mogra gajra
In Maharashtra, a gajra — a string of flowers worn in the hair, most often mogra jasmine — is tied for an ordinary Tuesday as readily as for a festival, one adornment made from a single flower. Mono bouquets in Mumbai work on the same principle: with no second variety to soften or sharpen it, the choice comes down to which flower and which colour do the talking. That makes picking one simpler than it looks, once the occasion is clear.
Orange gerberas or white lilies: with one variety, colour is the message
A mixed bouquet lets its colours soften each other, a pink stem sitting next to a cream one, a touch of green breaking them up. A mono bouquet has none of that company to lean on. Whatever shade the chosen flower comes in becomes the whole statement, so the colour here carries more weight than it would in any mixed arrangement.
The gajra itself is usually white, worn without a second thought on any ordinary day. A white bouquet, though, tends to land differently: Hindu funerals are marked with garlands of marigold, white roses and jasmine, and an all-white mono bouquet can read the same way to someone who isn't expecting it. For a happy occasion it helps to take the colour instead of leaving it out: a bunch of orange or yellow gerberas, a head of sunflowers, a hydrangea in pink. White lilies or a cloud of gypsophila still have their place, but keep them for a recipient who favours white themselves, or for news that calls for something quieter.

Chrysanthemums, orchids and hydrangea, flowers Dadar's stalls know too
Dadar Flower Market, phool gali by the station's western exit, runs under the flyover along Senapati Bapat Marg with stalls of lotus, marigold, rose and tuberose, and orchids, hydrangea and chrysanthemums sit among them. A bouquet here is made up to order rather than pulled off that market, but the three flowers are familiar faces on the same stretch of road, and each keeps its own section for a single-variety bunch.
Hydrangea carries its flowers in one dense round head, so a handful of stems already reads as a full hydrangea bouquet rather than a sparse one; Hydrangea in a Pink Jacket is built on exactly that head. Chrysanthemums and a cut orchid bunch are worth knowing for a different reason: both tend to last two to three weeks in a vase, longer than most cut flowers. That makes either one a safer pick when the gift needs to outlast the week it arrives in. How the weather and the calendar shape that choice through the year is covered under how flowers fare through Mumbai's year.
Mono bouquet delivery in Mumbai to a flat or an office floor
Every bouquet is made up after the order comes in, not pulled ready-made off a shelf, and the florist photographs the finished arrangement before the courier sets off; anything that still needs changing can be fixed from that photo.
An office delivery needs the company name and the floor. Where a building runs a pass system, the bouquet is left at reception instead, and the sender is told who signed for it. Most orders go out the same day they are placed, and the exact timing for a given bouquet shows on its own page; delivery to the city centre costs nothing, and the rest is covered under delivery details.
A recipient without a vase to hand is worth planning for. A flower basket solves that on its own, since it stands on its own base and needs nothing to stand in.

For a bright, happy occasion, orange gerberas make the point on their own, no card needed. For a gift that has to last, chrysanthemums or a cut orchid bunch outlast most mono bouquets in Mumbai, and either is a sound place to start.
