Surrounded by untamed jungle, I wipe the beads of sweat from my brow as I trek through the brilliantly green, steamy rainforest. I could be in the Amazon.

But I’m not in an exotic land, I’m in the Eden Project’s rainforest biome, a cavernous dome containing a staggering 1154 different plant species, which has been hailed the largest conservatory in the world. With a sticky, hot temperature that sits between 18˚C and 35˚C, the 50m high and 240m long biome is alive with streams, trees, flowers and a waterfall.

West African farm

To complete the notion of a living theatre of plants and people, the gargantuan conservatory contains a West African farm, where coffee and cocoa grows and tie-dyed shirts hang on a washing line. Alongside this is a Malaysian jungle home, made entirely from bamboo (so-called, we are told, because of the noise it makes when it burns – “bam … boo”).

As we roam through the frangipani-fragranced dome, we learn everything about rainforest agriculture, from the history of cocoa production and the banana trade, to the medicinal power of plants, such as the innocuous looking Madagascar periwinkle, a pretty pink flower used to treat childhood leukaemia.

Mediterranean biome

The smaller Mediterranean biome is a microcosm of plant life from South Africa, southwest Australia, central Chile and California.

My journey begins with Greek-style white-washed walls flanking a gold mosaic pavement, before I’m confronted with a bevy of brightly coloured flowers and trees. People-sized sculptures of Dionysus, Greek god of wine, dance through vineyards, labelled with the name of the grapevine and the wine it produces.

Recycle, recycle

Outside the biomes, a giant bumblebee sits alongside a rainbow of flowers and a variety of Cornish crops. There’s also a sinister model of a skeletal creature constructed entirely out of electrical products, such as irons, computers, washing machines and microwaves, providing a visual reminder of the importance of recycling. Named WEEE man, the model is made of the 3.3 tonnes of waste electrical products that the average person in the UK chucks away in a lifetime.

Honeycomb design

Sited in the depths of a disused china clay pit and surrounded by rolling green countryside, the Eden Project’s giant biomes make for a striking sight, with a futuristic and space-age feel. The hexagon design of honeycomb provided the inspiration for the design of the biomes. The transparent roofs are made from a type of plastic called EFTE that unlike glass, transmits UV light, so wear a sunhat if you visit in the summer.

Sexy flowers

The Eden Project is sexed-up horticulture, and visitors certainly don’t have to be green-fingered gurus to enjoy this global garden, which seeks to entertain while educating people about the importance of plants to our lives. The environmental message is strong throughout the complex: we can’t survive without plants. You have to see it to Adam and Eve it.
