Forever roses in Chicago: three buds under one dome, or a velvet box
Forever roses in Chicago often come three to a glass dome, in red or powder pink, not only as a single bud, and the count climbs with the case up to nineteen in a velvet hat box. The case decides both the number of buds and the size of the gift, while the choice between a fresh rose and a forever one decides how long that gift needs to last.
One bud or three under glass: the dome as the smallest gift
A glass dome holds either one bud or three. Three buds under one dome come only in red or powder pink, set close enough together that the colour reads as a single block rather than three separate flowers.
A single bud under the dome also opens in white, purple and blue, alongside red and powder pink. The extra shades come from a dye added to the same glycerine-based solution the stem draws up.
The rose itself is real. It is cut at the moment it opens and stays at the stage at which it was cut. Sellers of this kind of rose say one kept under glass tends to sit towards the upper end of its one-to-three-year range, because the dome keeps dust and draughts off the petals. Choosing a single bud or three under a glass dome really means choosing between a small, quiet gift and a slightly bolder one in the same case.

Four to twenty-five in clear acrylic, nine or nineteen in velvet
Once a gift needs more than three buds, the case changes. A clear acrylic case takes anywhere from four up to twenty-five buds, in red, powder pink or white, and its flat sides make every bud visible at once.
A velvet hat box closes with its own lid and holds either nine or nineteen buds, which suits roses that should stay covered until someone lifts the lid. A heart box holds exactly thirteen red roses set into the shape, which settles the colour and the arrangement before you even open it.
In the US an even or odd count barely matters on its own, so the choice between a clear acrylic case, a velvet hat box and thirteen red roses set in a heart comes down to size and colour rather than the number itself.
A rose for the week or one for the shelf: choosing in Chicago
A fresh rose in a vase lasts about a week, sometimes closer to ten days. Local cut flowers follow the Midwest's own calendar here, since the Chicago Flower Market sells from thirty-one regional farms, but only from May to October.
A forever rose answers to no season at all: the roses sold this way are already finished and simply wait on a shelf. Kept indoors, away from direct sun, which fades the dye over time, and dusted now and then with a soft dry brush, one can last anywhere from one to three years.

The florist photographs the finished gift before the courier sets off, and delivery across the city works the same way for sending flowers to a Chicago hotel or from abroad.
Where to start depends mostly on the room the rose will sit in. A single bud under glass suits a desk or a narrow shelf, a hat box with nineteen roses fills more space on a sideboard, and a heart box with its thirteen red roses already says what it means without any note attached.
