Britain's rarest plant is set to go on public display at Kew Gardens

Those wishing to enjoy what might be a once-in-a-lifetime chance to see flowers such as the lady’s slipper orchid should probably start planning now.

Some 20 plants you may not have seen before — all of which are classified as Extinct in the Wild, Critically Endangered, Endangered or Vulnerable — will make a rare appearance at the Royal Botanic Gardens, Kew, London TW9, next month. These include ‘Britain’s rarest wildflower’, lady’s slipper orchid, which fell victim to ‘orchidelirium’, the widespread Victorian fever for orchids that even led to collectors’ deaths on expeditions.

There will also be a chance to see one-time Cape Town resident Erica verticillata, with its pink tubular flowers, now extinct in the wild; and red angel's trumpet (or Brugmansia sanguinea), a plant used by South American shamans for its psychoactive properties.

‘The quest to care for and propagate these rare plants is a vocation and this exhibition will be a celebration of the work of our dedicated horticulturists who care for these specimens,’ says a spokesperson.

Visitors to the Rooms of Rarity and Extinction in the Temperate House will be able to learn how Kew’s experts care for plants — usually far away from the public eye in the Tropical Nursery — that are red-listed by the International Union for Conservation of Nature, in the hopes of halting biodiversity loss.

Each will be displayed alongside artefacts from the Herbarium, Economic Botany Collection and archives.

‘Rare and Extinct’ runs from October 19–November 17. See kew.org/kew-gardens/whats-on/rare-and-extinct for more details.

Annunciata Elwes

Annunciata grew up in the wilds of Lancashire and now lives in Hampshire with a husband, two daughters and an awful pug called Parsley. She’s been floating round the Country Life office for more than a decade, her work winning the Property Magazine of the Year Award in 2022 (Property Press Awards). Before that, she had a two-year stint writing ‘all kinds of fiction’ for The Sunday Times Travel Magazine, worked in internal comms for Country Life’s publisher (which has had many names in recent years but was then called IPC Media), and spent another year researching for a historical biographer, whose then primary focus was Graham Greene and John Henry Newman and whose filing system was a collection of wardrobes and chests of drawers filled with torn scraps of paper. During this time, she regularly gave tours of 17th-century Milton Manor, Oxfordshire, which may or may not have been designed by Inigo Jones, and co-founded a literary, art and music festival, at which Johnny Flynn headlined. When not writing and editing for Country Life, Annunciata is also a director of TIN MAN ART, a contemporary art gallery founded in 2021 by her husband, James Elwes.
