Syngenta's ‘Delta Midnight Sun’ pansy and Ball Colegrave's ‘Sorbet Pink Halo’ viola were chosen by the public as their favourite plants in a display of 5000 pansies and violas at RHS Wisley.
The display is part of a new initiative which has seen the RHS team up with the HTA, growers and breeders to promote seasonal plants and will lead to the creation of the RHS People's Choice brand.
The RHS created a display with a huge range of colours and varieties and invited the public to vote for their favourite.
RHS head of horticultural trials & relations Kylie Balmain said: "The strengthening relationship the RHS has with breeders and growers means we can work together to promote interesting plant groups to the one million people who visit RHS Wisley every year.
"We have been overwhelmed by the public interest in the display, and the bulging clouds of colour make us all feel great; there is also the fantastic role they play in providing a food source for pollinators.
"The interest from our visitors and the response from RHS staff confirm that these simple, happy and energetic plants have an important role to play in our gardens.
"With the continued support of the HTA and horticultural trade the RHS is planning a summer display at RHS Garden Wisley that will focus on Begonia, with the ambition of developing an ‘RHS People’s Choice’ brand to raise the profile of selected plant groups and more directly support retail sales of seasonal impact plants."
