Pearson, of Dan Pearson Studio, will speak at the AIPH International Green City dinner, held on board HMS Belfast after the conference which will be held on 1 April at One George Street, London.
He is expected to outline the project and his planting design aims, giving guests a present-day example of what can be achieved through urban greening.
The Garden Bridge, which has attracted the support of actor Joanna Lumley and a £30m pledge from the Government, aims to provide a floating garden and public green space on a bridge across the Thames. It has been designed by Heatherwick Studio, known for the London 2012 Olympic flaming cauldron and, if remaining funds can be raised and planning permission granted, will start construction in 2015.
Pearson and his team have developed a soft landscape planting scheme with five distinct character areas that reflect the development of plant species from wild pioneers to ornamental garden cultivars.
The conference – aimed at planners, local authorities, health authorities, the construction industry, landscape architects, green space experts, landscapers and the horticultural industry - features speakers from three continents who have been deeply involved in greening cities.
Mayor Annemarie Jorritsma, former Deputy Prime Minister and Minister for Economic Affairs in The Netherlands, has made the greening of Almere a priority for her administration.
Two speakers are due to attend from China. Monica Kuo from the Chinese Culture University in Taipei will show how theory has been put into practice to bring about real greening change in Asia while deputy general secretary of the China Flower Association and the Eco-culture
Association Hongming Peng will give an overview of China’s approach to greening cities.
Dr Anthony Kachenko from Nursery Garden Industry Australia is one of the drivers behind Australia’s ‘202020 Vision’ campaign which aims to have a country with 20 per cent more green space by 2020.
And from the UK Mark Camley, executive director of park and venues at the London Legacy Development Corporation will illustrate how the development and legacy of the Queen Elizabeth Olympic Park can be used as an international example of city greening for the long term.
Other speakers include president of the Royal College of Physicians Sir Richard Thompson, president of the Planning Officers Society Mike Kiely, Tom Butterworth of Natural England and Leigh Hunt principal horticultural advisor at the RHS.
