Collection: Vases

The vase decides how the flowers sit

A bunch of flowers has no shape of its own. It takes the shape the vase gives it, and most disappointing arrangements are a good bunch in the wrong vessel. Two measurements do almost all of the work: the width of the neck and the height of the body.

A narrow neck gathers stems and holds them upright, which is why a single stem looks deliberate in a bud vase and lost in a jug. A wide mouth lets stems fall outward, which suits a loose supermarket bunch and ruins three tulips. Before buying, look at what you usually bring home. If it is a wrapped bunch from a shop, you want width. If it is one or two stems from the garden, you want a neck narrow enough to hold them.

Vase shapes, and what each one is actually for

Shape names get used loosely, and the same vessel is sold under three of them. What matters is the relationship between the opening and the body.

How tall should the flowers be?

The florist rule of thumb is that the arrangement stands one and a half to two times the height of the vase, measured from the base to the top of the tallest bloom. It is a guideline rather than a law, but it explains why a bunch can look wrong without anyone being able to say why.

So a 12 inch vase carries flowers standing 18 to 24 inches overall, which means stems around 20 inches before you trim. A 6 inch vase wants blooms sitting 9 to 12 inches high. Buy the vase for the stems you actually get, because trimming down is easy and stretching a stem is not.

The exception is the low dense bowl, where the point is that nothing rises much above the rim. There the flowers sit at or just over the edge, and the ratio does not apply.

Glass, ceramic or metal

The material changes more than the look. It decides whether you see the stems, how often you have to clean it, and how much of the arrangement you are responsible for.

Making cut flowers last

Most of what shortens a vase of flowers happens in the first ten minutes. Bacteria block the stem, and a blocked stem cannot drink no matter how much water sits around it.

Start with a vase that is properly clean, not just rinsed. Cut each stem at an angle so the cut end never sits flat against the bottom. Strip every leaf that would sit below the waterline, because a submerged leaf rots within two days and feeds the bacteria that block the stems. Then change the water every couple of days rather than topping it up, and keep the vase out of direct sun and away from a bowl of fruit, since ripening fruit gives off ethylene and ethylene ages flowers.

Cleaning a cloudy vase

Cloudiness in a glass vase is usually two separate problems that arrived together: a mineral film left by hard water, and a bacterial film left by flowers. Detergent removes neither, which is why a vase can come out of the dishwasher still hazy.

White vinegar dissolves the mineral film. Fill the vase, leave it an hour, longer if the haze is old. For the bacterial film, add a spoonful of uncooked rice and swirl: the grains scour the inside of a narrow neck that no brush will reach. A denture tablet dropped into warm water does both at once and takes about twenty minutes, which is the least effort of the three.

If the haze survives all of that, it is etching rather than film. The glass surface itself has been eaten by minerals over years, and nothing brings it back.

A vase does not need flowers in it

Fresh stems are the most demanding thing you can put in a vase and the shortest lived. Dried grasses, bare branches in winter, a single eucalyptus stem that lasts a season: all of them read as deliberate and none of them need water.

Empty works too, if the shape is good enough to look at on its own. That is the honest test of a vase, and it is the one worth applying before you buy: does it hold its own on the shelf on the days you have not been to the market?
