A ROOM covered in chocolate will be the most edible major show in the Scottish art scene this summer.

The acclaimed Jupiter Artland gardens and galleries, 12 miles outside Edinburgh, are to stage Stroke, a work by the acclaimed ­Scottish artist Anya Gallacio that will involve covering the walls of the gallery with 40kg of rich Belgian Callebrutt dark chocolate.

The piece, which will be in place from May 17 to July 13 as a key part of the Artland's summer season, will slowly decay but until then, visitors can view the work or even eat it, if they wish.

Other works this summer at the venue, by Bonnington House near the small village of Wilkieston in West Lothian, will include a new large scale illuminated work by the Turner Prize-nominated Scottish artist Nathan Coley.

Jupiter Artland, which opened in 2009 and is owned and run by Nicky and Robert Wilson, features 30 site specific works by artists including Ian Hamilton Finlay, Andy Goldsworthy, Antony Gormley, Anish Kapoor, Jim Lambie, Cornelia Parker, Marc Quinn and large landform sculpture by Charles Jencks.

Nicky Wilson said she will be interested to see how visitors react to Gallacio's sweet art work, which was first shown in 1993 but has not been seen since 1994.

She said: "Each time it has been shown the reaction has been different - It will be interesting to me to see what Edinburghers will do: will there be tongue marks in the chocolate?

"I am sure children will be very interested."

The Artland is part of the nationwide Generation ­exhibition of contemporary Scottish art this summer, and will also feature work by Katie Paterson, Tessa Lynch, Mick Peter, Silvy Weatherall and Jessica Harrison.
