Visitors travel from the Amazon rainforest to the desert of northeastern Brazil to encounter glowing hanging droplets clothed in tillandsia hanging among Brazilian cacti. Others include a tunnel of tropical plants and two huge rainforest tree structures swathes in oncidiums and bromeliads.
Five explosive figures made from bromeliads and phalaenopsis as well as Brazilian hybrids such as Cambrias and Miltonias will take centre stage in the pond, referencing the costumes of Brazilian carnival dancers.
Display horticulturalist Elisa Biondi said: "This year the pond display will be a true explosion of colour - a real carnival. With 2016 being the year of Brazil, we wanted to capture the essence of this incredible county, taking visitors on a journey through its biomes while showing the range of conservation and science work that Kew is doing with South America."
Talks, courses, tours and more will be running throughout the festival. The full programme is available on the Kew website.
