Glittering glasshouses

Blissfully warm, the UK’s glasshouses offer the chance to sample tropical floral delights from around the globe, says Daniel Graham

Top seven, nationwide

01 LOGAN BOTANIC GARDEN, DUMFRIES AND GALLOWAY

Built less than 10 years ago, the Victorian-styled Logan Conservatory was the first public glasshouse in the UK to be heated by green energy sources. Its solar panels and air-source heat pumps maintain a temperature of 18°C – perfect for the South African plants within. £7.50 per adult. rbge.org.uk/visit/logan-botanic-garden

02 RHS GARDEN WISLEY, SURREY

There are three climatic zones to explore in Wisley’s 12-metre-high glasshouse: tropical, moist temperate and dry temperate. The steamy tropical area is filled with bananas, bromeliads and climbers. In the moist temperate zone you’ll find giant ferns and epiphytes, while in the dry zone, desert cacti thrive. £15.70 per adult. rhs.org.uk/gardens/wisley

03 THE EDEN PROJECT, CORNWALL

The stunning Rainforest Biome at the Eden Project is so big that it takes most visitors one-and-a-half hours to navigate its raised walkways and undercanopy paths. The planting replicates four of the world’s rainforest environments: tropical islands, South East Asia, West Africa and tropical South America. Be prepared to share your experience with the resident roul-roul partridges and Sulawesi white-eye birds. £32.50 per adult. edenproject.com

04 NATIONAL BOTANIC GARDEN OF WALES, CARMARTHENSHIRE

Designed by Norman Foster and Partners, the Great Glasshouse here is the largest single-span glasshouse in the world. This great dome is also home to the largest collection of Mediterranean plants in the northern hemisphere. The landscape, designed by Kathryn Gustafson, combines rocky terraces, sandstone cliffs and gravelled scree slopes. £12.50 per adult. botanicgarden.wales

05 THE WINTER GARDEN, SHEFFIELD

At 70 metres long and 22 metres high, this oasis in the heart of Sheffield is Europe’s largest urban glasshouse. Built from sustainable larch, it’s home to more than 2,500 plants from all corners of the world. The Winter Garden is a public space, free to access, and even has independent shops and a café within its glass walls. theoutdoorcity.co.uk/sheffield-city-life/attractions/sheffield-winter-garden

06 BELFAST BOTANIC GARDENS, BELFAST

The foundation stone for Belfast Botanic Gardens’ iconic Palm House Conservatory was laid in 1839. Built by master engineer Richard Turner of Dublin, it’s one of the earliest examples of a curvilinear cast-iron glasshouse in the world. Two wings – cool and tropical – house an international cast of plants. Entry is free. visitbelfast.com/partners/botanic-gardens

07 DOWN HOUSE, KENT

Darwin was the first person to scientifically prove that insectivorous plants digest insects to gain nutrients, rather than pulling nutrition up through their roots from the ground. His Kent home, and in particular his greenhouse, is testament to this, housing a superb collection of sundews, on which most of Darwin’s work was based. There’s also a selection of climbing plants to see. £17 per adult. english-heritage.org.uk/visit/ places/home-of-charles-darwin-down-house
