Why Do Flowers Not Smell Anymore? A Florist Explains

Most cut flowers smell less than they used to because they have been bred for long vase life, large heads and stems that survive days of transport, and fragrance usually loses out in that trade. On top of that, flowers are often cut in bud, kept cold for long stretches and sold at an age when their scent has not yet developed or has already faded. So a rose that filled your grandmother's garden with perfume can seem almost odourless when it comes from a bucket.

Scent has not vanished from the plant world, though. It has become something you need to ask for. Below we explain, the way we would explain it to a customer at the workbench, what actually happens to fragrance between the field and your table, how to tell whether the problem is the flower or the room, which varieties still smell wonderful, and how to make sure the bouquet you send to someone in Russia arrives with its perfume intact.

Breeding for the vase, not for the nose

For most of the twentieth century, breeders selected cut roses, carnations and chrysanthemums for traits that buyers could see and that growers could sell: bright, even colour, a firm head that does not shatter, straight stems and, above all, a vase life of ten days or more. Fragrance was rarely on the scorecard, partly because it is hard to measure and partly because it does not show in a photograph or a catalogue.

The result is that many of the most popular commercial varieties simply carry fewer of the genes involved in producing scent compounds. Researchers studying roses have found that the pathways that make classic rose fragrance are often weak or switched off in modern long-stemmed hybrids. Nobody removed the scent on purpose; it was quietly lost while other qualities were chosen again and again.

There is also a practical trade-off. Thick, waxy petals that resist bruising tend to release fewer volatile oils than the thin, silky petals of old garden roses. That is why a tight red hybrid on a long stem can last two weeks in your vase yet barely smell, while a loose, cupped garden rose drops its petals sooner but perfumes the whole room.

Fragrance is expensive for a flower to make

Scent is not a decoration added for us. It is a chemical message to pollinators, made from volatile compounds that the petals produce and release into the air. Making those compounds costs the plant sugar and energy. A flower that is putting its resources into staying fresh and firm in a vase has less to spend on perfume, and once a stem is cut it has no roots feeding it, only the water and sugars you give it.

Many flowers also release scent on a schedule. Roses and lilies usually smell strongest in the warm part of the day, while jasmine, tuberose and night-scented stock open their perfume in the evening, when the moths they evolved with are flying. If you sniff a lily on a cool morning and then again at eight in the evening in a warm room, you may think they are two different flowers.

Pollination matters too. A flower that has been pollinated often stops producing scent, because its job is done. In a bouquet this rarely happens, but it explains why lilies with their pollen removed by the florist still smell strongly: the anthers are gone, not the flower's reason to call for visitors.

Cold storage, early cutting and the age of the bloom

Commercial flowers are usually cut while still in bud so that they can travel. Many of them develop most of their fragrance only as the petals open, so a rose cut very tight and kept at a few degrees above zero may never reach its full scent. Cold slows everything down, including the production of the oils you can smell.

Time works against you at the other end as well. Scent tends to peak a day or two after a bloom opens and then fades, even while the flower still looks fine. A bouquet that has spent a long time in a cold room before it reaches you can look fresh and smell of almost nothing, because the moment of peak fragrance has already passed.

That is why it is worth asking for scented flowers when you order, rather than hoping a bouquet will happen to smell. If you want to understand how to coax back some of the scent once the flowers are home, we have a separate guide on why flowers lose their scent and how to bring it back.

When the problem is the room, not the flower

Before you blame the bouquet, check the conditions around it. Fragrance is carried by molecules that evaporate, and they evaporate faster in warmth. A vase standing in a cool hallway or next to an open window in a Russian autumn will smell much weaker than the same flowers on a warm kitchen table. Moving them for an hour into a warmer room often brings the perfume back.

Your nose also adapts quickly. After a few minutes in a room with a strong scent, you stop noticing it, while a guest walking in will say the flat smells of lilies. Step out for a while and come back, and you will usually smell the flowers again. Strong competing smells, such as cooking, candles or air fresheners, can mask delicate fragrances like freesia or sweet pea completely.

Finally, give the stems what they need. A fresh diagonal cut, clean water changed every day or two and a vase away from radiators and fruit keep the flower alive and working, and a living, well-hydrated flower is the one that keeps producing scent. Ethylene from ripening fruit speeds up ageing, so a bowl of bananas next to the vase shortens both its life and its perfume.

Flowers that still smell beautiful

Some flowers have kept their perfume through every round of breeding, and they are the ones to choose if scent matters to you. Oriental lilies are the strongest of all: two or three stems can scent a whole room. Freesias have a light, fresh, slightly peppery fragrance that most people love. Hyacinths in late winter and spring smell sweet and intense, and lilac, when in season, is pure nostalgia for many people who grew up in Russia.

Among roses, look for garden and spray varieties with an old-rose look: cupped or rosette-shaped heads, many thin petals and softer colours such as blush, apricot and cream. These are much more likely to smell than the classic tall red rose with a pointed bud. Peonies, in early summer, usually have a rich, rosy scent, although some varieties are almost odourless, so it is worth asking.

Smaller supporting flowers add fragrance too. Stock (matthiola) has a warm, clove-like smell, sweet peas are delicate and honeyed, and eucalyptus brings a clean, green note to the greenery. Chrysanthemums, alstroemeria, gerberas and most tulips are lovely for colour and vase life but have little or no scent, so a bouquet built only from them will look cheerful and smell of very little.

How to send a fragrant bouquet to someone in Russia

If you are ordering from abroad and want the flowers to smell, say so. Browse the bouquets catalogue for a style you like, then write to a manager on WhatsApp: you can ask for scented flowers to be included, agree the time, the address and the text of the card, and ask for a photo of the bouquet before delivery. A card with your message is free.

Timing helps the scent too. In large cities express delivery takes 1 to 2 hours after the order is confirmed, or you can choose an exact time (plus or minus 30 minutes) or a window: 09-12, 12-15, 15-18 or 18-21. You can also pre-order 1 to 30 days ahead, which is handy for birthdays and anniversaries. An evening window suits lilies and tuberose well, since they smell strongest later in the day.

City delivery costs 500 RUB; for remote districts and suburbs the operator confirms the price when confirming the order. The courier calls the recipient about 15 minutes before arrival, and delivery is anonymous by default unless your card says who the flowers are from. You can pay online on the site by bank card, SBP or Yandex Pay; the details are on the delivery and payment page.
