Growing just a few ornamental plants — such as daffodils or petunias — in a bare front garden can make people feel happier and less stressed, a study found.
Experts led from the Royal Horticultural Society planted blooms including azaleas, clematis and lavender in yards in low-income areas of Salford, Greater Manchester.
They then monitored the stress levels of the residents participating in the study — and explored how the additions to their gardens made them feel.
The researchers recruited 42 residents — involving a total of 38 gardens — for the study, although some received their plants only after a year as so that they could serve as a control group in the meantime.
Residents were each given one tree, one shrub, one climber and enough smaller plants, bulbs and bedding plants to fill two containers.
They were not required to look after the plants, as the containers could ‘self water’ as they had a 22-litre in-built reservoir — the participants were encouraged to take part by gardening their plot, with help from the Royal Horticultural Society advisors.
The team measured each residents’ levels of key stress response hormone cortisol both before and after the plants were added.
They found a higher proportion of healthy daytime cortisol patterns after planting, suggesting that the residents had a better health status.
The research found that only 24 per cent of residents had healthy cortisol patterns before the plants went in, but over the year following the greening of the front gardens, this increased to 53 per cent.
