Scent comes into its own when you’re sitting outside on a balmy summer evening, taking in all the delicious fragrances the garden has to offer.

I have two neighbours to thank for the sweet scent of mock orange which fills the air in my own garden – the fragrance wafting quite a distance from where these flowering shrubs are planted.

There are fragrant plants for every garden throughout the year, from winter-flowering jasmine and mahonia to hyacinths, scented narcissus and viburnum in the spring, and summer-flowering lavender, rosemary, honeysuckle, roses, evening primrose, dianthus, nicotiana and stocks.

It’s worth noting that the most strongly-scented flowers are often white, or insignificant in appearance, but make their presence felt when you sniff the air.

While flowers tend to have sweet, heady perfumes, leaf scents tend to be spicy. Many plants with scented foliage need gentle stroking or pinching to release their perfume. It’s likely that the scents evolved as a deterrent to insect pests, but gardeners love them.

New research from PlantforLife, an advice resource created by the Horticultural Trades Association, reveals 63 per cent of people in the UK buy floral and herbal-scented products to enhance their health and well-being, yet when asked, just 32 per cent realised the plants they grow in the garden can provide the same effects.

To address this lack of awareness and promote the benefits floral and herbal scents provide, PlantforLife has joined forces with aromacologist, Daniele Ryman, and celebrity plantsman Chris Collins, to show people how to give their garden a simple and healthy-scented makeover.

“Although colour is an important part of any outdoor space, introducing different scents into your garden is essential to creating your perfect outdoor haven,” says Chris. “Having beautifully-scented plants outside not only means you can reap the health benefits, but planting a scented garden is a great way to help the environment and attract wildlife, like bees, back into your garden.”

Roses are believed to have a calming fragrance which can help ease nerves.

Lavender is well-known for relieving stress, helping relaxation and aiding sleep. It is best planted in numbers, makes an ideal low hedge in the traditional cottage garden and doesn’t need really rich soil. However, it will need plenty of sun.

Lily-of-the-valley, whose scent helps combat tiredness, only grows to 45cm and is ideally planted in moist shade under trees to make an effective ground cover.

Rosemary is known to be an energiser, and will thrive in sandy soil in a sunny position. Water it well in its first season, and then it should become reasonably drought-resistant.

Fragrance is best captured in sheltered spots or on a patio, so make sure your pots or nearby beds are awash with a range of fragrant blooms to make the most of those delicious scents in the summer months.
