A Norwich-based firm's 'naked' garden won a silver medal at yesterday's Hampton Court flower show and was visited by the Duchess of Cornwall.

Anglian Home Improvements' garden was designed by TV landscape designer David Domoney and was praised by the panel of selected RHS judges for its ground-breaking innovation.

Some of the leading horticultural scientists in Europe worked with Mr Domoney to create a completely 'naked' garden.

Plants were sourced from America, Brazil, the Netherlands, and Thailand and some of the best varieties that can grow without soil were used to produce flowers, foliage, fruit and vegetables.

Building on Anglian's glazing technology, which is always 'invisible' to the homeowner's eye, Mr Domoney exposed plants in a series of cleverly constructed glass containers and transparent materials to show the beauty of 'naked' plants and exposed what is traditionally left undiscovered.

Mr Domoney said: 'Our 'naked' garden showcases some of the world's most striking plants in a completely different light and we're delighted to be recognised for creating something the gardening world loves.

'Using clever glass technology which allows plants to grow soil free in glass containers, garden lovers are able to discover a whole new side to the world of plants.'

Anglian's marketing director Martin Troughton said the garden was 'unique'.

He said: 'It's been a real privilege to win an award once again at this prestigious event.

'A huge thanks must go to David Domoney and his team for their creativity and hard work, ensuring that we create a garden that people love.'

Plants in the 'naked' garden include the standard rose, Arum Lily, water chestnut, tomotoes, aubergines and lettuce.

The plants can survive for weeks in the water and the team was able to grow the crops by feeding them a carefully measured dose of nutritional feed, keeping the water at a temperature of less than 30 degrees centigrade, enriched with oxygen, to replace the nutrients normally derived from the soil.

The team worked hard to prevent the growth of algae, which would normally be achieved by keeping the water, the nutrients and, therefore, the roots in a dark environment.

For the 'naked' garden, they reversed this process, exposing the roots to light.

The other Norfolk winners at the show were Amulree Exotics, from Norwich, which won the bronze flora award in the floral marquee category, Bill Le Grice Roses, from Wroxham Barns, which won the silver flora award in the rose festival category, and Peter Beales Roses, from Attleborough, which won the silver gilt flora award, also in the rose festival category.

The RHS's Hampton Court Palace Flower Show started yesterday and runs until July 10.
