Sir Elton John has lent his artistic talents to a prestigious annual flower show in London by decorating a garden gnome to raise money for charity.

Organisers of the Royal Horticultural Society (Rhs) Chelsea Flower Show have previously banned the inclusion of gnomes in their outdoor displays, but they lifted the ruling to invite a number of stars to design their own in support of a campaign to educate children about gardening.

The Your Song hitmaker signed and styled his gnome to resemble one of the characters from 2011 animated film Gnomeo & Juliet, which was produced by his film company.

The singer also donated a signed set of the Gnomeo & Juliet figurines, which will be displayed along with other gnomes which have painted and signed by stars including Dame Helen Mirren and Dame Maggie Smith.

The gnomes will be on display for the duration of the Flower Show at the Royal Hospital in Chelsea, London this month (21-25May13) and later auctioned on eBay.com to raise money for the Rhs Campaign for School Gardening, a nationwide drive to encourage youngsters to take up green-fingered activities.
