Back in 2015, I began searching for the top plants to make us happy
This award winning Chelsea Flower Show exhibition used facial recognition software to explore which plants make us most happy.
The three-month Positive Power of Plants campaign was designed to raise awareness of the positive impact that plants have on our lives.
I asked you to nominate plants that make you feel happy, and then you all voted to find your top 20.
These suggestions were then used to create a medal-winning cutting edge exhibit at the Chelsea Flower Show in 2015.
This scientific exhibit showed images of the plants and monitored visitors with special facial recognition cameras developed by software company Premier Epos.
The pioneering cameras tracked engagement, eye movement and expression to find out which plants were most popular.
Screens showed visitors as their faces were recognised by the cameras.
The computer databanks then pulled out the top three plants for their age group and gender.
On a completely volunteer basis, the audience queued to take part in our search for Britain’s happiest plant.
Participants for the exhibit, were made up from a diverse pool of people from across the country and included HRH Prince Philip himself.
Results: Top 3 happy plants
1. Lily of the Valley
This is the nation’s winning plant! Over 30,000 people visited our stand, and this is the plant that attracted all the attention.
It has become a hugely popular plant in people’s gardens. It triggers memories of walking in the woods and seeing the sprays of flowers – they are marvellous plants. They have little bell-like flowers that nod in the wind.
They are also a doddle to grow at home! Once in the ground, they spread by rhizome root systems. This means that they will spread easily underneath trees and in shady spots they quickly colonise the ground.
Lily of the valley is also an evocative plant – it was in Kate Middleton’s wedding bouquet.
N.B. Please remember that lily of the valley is a very poisonous plant – take care when growing it if you have small children.
2. Sweet pea
Many people at Chelsea told me that seeing sweet peas triggers memories of their childhood, time spent working in the garden with their grandmother.
Recently, I’ve been looking into how the scent of flowers can really lift your mood and this flower does exactly that.
Sweet peas are great plants to grow in your garden. They flower continually and they make great cut flowers. And the fragrance is stunning!
Sweet peas also come in a huge array of bright and pastel colours and I think the petals look like butterfly wings.

3. Jasmine
This is a very popular plant that evoked strong memories for those who took part on the day. The participants said that they reminded them of the plants they had growing in their own gardens.
That rich jasmine scent also reminded many people of holidays abroad and it’s so recognisable to so many people.
Jasmine is a fairly easy plant to grow at home in a sheltered spot. Look out for the summer flowering variety Jasminum officinale (common jasmine), which has those sweet scented white flowers.
Or look to the winter flowering variety Jasminum nudiflorum to brighten up your garden with buttery yellow buds during the off season.
P.S. Notice what all these happy plants have in common? A strong scent!
What else did we discover?
Our clever facial recognition cameras were able to calculate the age group and gender of visitors. So we have some fascinating insights into the plant preferences for different groups of people. Here’s a run down of some of the results:
What happens now?
This project is far from over! Over the past 4 years it has been run with Thrive charity, which helps people living with disabilities through therapeutic horticulture.
It’s amazing just how much the power of gardening and plants can nourish the soul and enhance our quality of life and their good work goes on. Plus, the National Garden Gift Voucher designs featured each of the flowers you loved the most – so thanks for watching out for them!
Over the last year, I’ve released a ‘Power Of Plants’ blog series to regularly continue to advertise the fact that plants have lots to give for our physical and mental health.
Later in 2019, I look to recapture information on which plants are happiest to you now – to find out if these have changed over the years since I began promoting this worthwhile topic.
So take my quiz to discover YOUR favourite flowers and get involved in the search!
