Flowers and Mood: What the Research Says

Almost everyone has noticed that a bouquet on the table or a flowering plant on the windowsill makes the day a little better. But can flowers really be called an "antidepressant" or a "cure for flu", as some websites claim? Let's look honestly at what scientists have actually found about flowers and mood, the benefits of gardening and caring for plants, and which popular claims about "healing" flowers don't hold up.

What research says about flowers and emotions

One of the best-known studies was carried out by psychologists at Rutgers University (USA) in 2005. Participants were unexpectedly given a bouquet, a candle or a fruit basket. Flowers, more than the other gifts, prompted a genuine "Duchenne smile", and those who received a bouquet still reported a better mood several days later. The researchers concluded that flowers are a powerful emotional signal that people perceive as a sign of care.

Other studies link indoor plants and a view of greenery to lower perceived stress and a more pleasant sense of space. In one study, post-surgery patients with plants in their rooms rated their wellbeing and mood more positively. These findings are interesting, but they are not proof that flowers cure illness.

Why flowers make us happy

• Colour. Bright warm shades feel energising, calm cool ones relaxing.
• Living nature. People generally find natural elements — greenery, flowers, organic shapes — pleasant. This is studied in "biophilic" design.
• Attention. A bouquet is above all a sign that someone is thinking of you. Much of the effect of a gift is social.
• Scent. Many people find lavender, rose or citrus scents pleasant and relaxing, though reactions to fragrance are very individual.

Caring for plants and gardening

It is one thing to look at flowers and another to look after them. Gardening combines physical activity, fresh air and a clear result: you plant, it grows, it flowers. Many countries use horticultural therapy — working with plants as part of rehabilitation and social programmes. Even houseplants offer a small but pleasant daily ritual of care.

Myths about "healing" flowers

• "Flowers cure flu and viruses." No. Volatile plant compounds (phytoncides) do not replace vaccination or treatment. If you have symptoms, see a doctor.
• "Houseplants purify the air in a flat." Lab experiments in sealed chambers are often applied to homes, but in a real room a few pots have little effect on air quality. Ventilation matters far more.
• "A bouquet can replace antidepressants." Flowers can lift your mood, but they don't treat depression. If low mood lasts for weeks, it's important to talk to a professional.
• "A strong scent is good in the bedroom." On the contrary, the heavy fragrance of lilies or hyacinths gives some people headaches.

How to bring more flowers into your life

• Put a small bouquet where you spend the most time — on your desk or in the kitchen.
• Choose seasonal flowers: tulips and daffodils in spring, peonies and wildflowers in summer, chrysanthemums in autumn.
• Get one easy-care plant and look after it — a simple daily ritual.
• Give flowers for no reason: research suggests an unexpected gift is especially delightful. Read why in why women love flowers.
• Choose colours to suit your mood — see bouquet colour combinations.
