The winning image by Rosanna Castrini
Rosanna Castrini, a garden designer from Italy, has won this year's prestigious International Garden Photographer of the Year top prize of £5000.
Judge Andrew Lawson said: "We all love single plant portraits - but it is much more difficult to make a successful picture of many plants together in association. To me, this picture is as close to perfection as you can get.
I love the contrasting shapes and textures of the three types of flower. All the plants are in perfect condition. The photographer has recognised a very skilful piece of planting and has made a straightforward rendering of it, in lovely light and with no tricks."
Nina Jonsson, from Norway won the RPS sponsored Portfolio prize of £2000 plus an RPS gold medal.
This year's exhibition, which is located in the Nash Conservatory at Royal Botanic Gardens, Kew, runs until 30 March. Entry to the exhibition is included in the entry ticket to the gardens.
