David Hockney donates his largest painting to Tate

Bigger Trees near Warter is 12m long and 4.5m high, and made up of 50 separate canvases


David Hockney has given Tate his largest painting, Bigger Trees near Warter. The work is over 12 metres long and 4.5 metres high, which probably makes it the biggest painting ever executed in the open air. Painted in oils, it comprises 50 separate canvases, hung together. The view is of a copse outside Bridlington, in Yorkshire, which is now Hockney’s main home.

Bigger Trees near Warter was painted just over a year ago and was a major logistical operation. An assistant took digital photographs of the paintings, recording every stage in their development and enabling the artist to see how the work was progressing in its entirety.

In June the picture went on public view, at the Royal Academy’s Summer Exhibition, where it took up a whole wall in the largest gallery. The RA presentation also coincided with Tate Britain’s exhibition on “Hockney on Turner Water­colours”, and conversations between the artist and the gallery eventually led to the donation.

Tate has 108 Hockneys, but most are on paper, and there are only eight paintings, including this latest acquisition. The value of Bigger Trees near Warter is not being revealed for the moment (the record price for a Hockney is for The Splash, 1966, which sold at Sotheby’s on 21 June 2006 for £2.9m). Its size will make showing the work complicated, but it is expected to go on temporary display at Tate Britain in autumn 2009, and after that to be hung on an occasional basis. A formal announcement on the acquisition is due shortly.
