The annual orchid festival is back at Kew and this year’s theme is Madagascar, which, thanks to its incredible biodiversity, is home to some of the world’s rarest plant species. You can get a little taste of Madagascar’s varied landscapes and native wildlife across the different zones inside the Princess of Wales Conservatory. As well as an array of orchid displays, there’ll be a range of plant sculptures on show, including giraffe weevils and ring-tailed lemurs, and an exhibition of Malagasy photographer Tina Waibel’s work.
