Large bouquets: what the size is actually made of
Volume can be built in three quite different ways, and the photograph rarely tells you which one you are buying.
The first is stem count. More flowers of the same kind, packed to a wider circumference, giving a heavy dome that reads as generous from across a room. The second is stem length, where the same number of blooms is cut long and given height instead of width, which suits a hallway console and looks slighter in the arms. The third is air: fewer focal heads, held apart by branching foliage and seasonal material, so the outline is wide while the flower count stays moderate. All three are legitimate builds, they simply behave differently once the paper comes off, and the airy one usually outlives the dense one because nothing is pressed against anything else.
Then there is padding, which is not legitimate. A hollow core, a thick collar of greenery hiding a thin arrangement, or a paper wrap far wider than its contents.
You can spot it in one movement: look at the bouquet from the side rather than the front. A genuine build keeps its depth at that angle, while a padded one flattens into a fan with a bare middle.
Weight, and how it is handed over
A full armful weighs about as much as a small backpack, and nearly all of that is water inside the stems. The load feels manageable for the first half a minute, then the forearm complains, because the mass sits high and forward while the grip point is narrow and low.
So a large bouquet is passed with both hands and received with both hands, laid along the forearm rather than clenched at the binding.
Girth is the other measurement people forget. The bundle will not close inside one palm, and the only comfortable place to hold it is right at the ribbon, where the stems are drawn together most tightly.
Transport follows from that. Upright in a lift, upright in the car, standing in the passenger footwell with a hand on it. Laid flat across a back seat, the heads crush under their own weight within a quarter of an hour, and the damage shows on the outer petals first.
The vase problem
Most households own nothing suitable, and this is where the first evening goes wrong. A standard vase either cannot take the diameter of the bundle at its neck, or it takes it and then tips over the moment the bouquet leans.
What works is a heavy base, a wide opening and a height of roughly half the bouquet, so the top does not lever the whole thing over. A thick-walled glass cylinder does the job; so does a clean bucket, for the first night, while you find something better.
Splitting the arrangement is the other honest answer. Two or three smaller vases in different rooms give every stem room to drink, and the lower flowers in a tightly packed bundle are always the first to fail.
Where it belongs, and when to choose something else
Position it away from radiators, out of direct sun and off any route people walk. A wide arrangement gets brushed by shoulders and bags, and each contact marks an edge petal.
A dining table is the worst place for one. Anything taller than seated eye level blocks the person opposite and gets moved before pudding.
Large bouquets earn their place where the first second matters: an anniversary, an arrival hall, a stage, an apology that needs to be visible. They are the wrong choice when the recipient in Munich lives in a studio flat or has to carry the thing across a restaurant, and in those cases a compact build of better stems does more for them than sheer size ever will.
