Bigger Trees Near Warter or ou Peinture en Plein Air pour l'age Post-Photographique is a large landscape painting by British artist David Hockney.

Measuring 460 by 1,220 centimetres or 180 by 480 inches,[2] it depicts a coppice near Warter, Pocklington in the East Riding of Yorkshire and is the largest painting Hockney has completed.

[4] The painting, a landscape near the village of Warter, between Bridlington and York, is set just before the arrival of spring when trees are coming into leaf.

Much of the painting's extensive upper half is devoted to the intricate pattern of overlapping branches, clearly delineated against a pale winter sky.

From 2004 onwards he spent increasing lengths of time in Yorkshire; the rolling chalk hills around Bridlington became the focus of his art.

In 2006 he made a series of nine large landscapes of Woldgate Woods, returning to the same spot between March and November to chart the changing seasons.

[3] On a trip to Los Angeles in February 2007, looking at images of his Woldgate Woods paintings, Hockney had the idea of working up the same scene over a much bigger scale.

His usual procedure when working in the landscape is to load a pickup truck with paints and materials and drive to the location.

Each individual panel was painted in situ and as they were completed his assistant, Jean-Pierre Gonçalves de Lima, would digitally photograph them and then make them into a computer mosaic.

Hockney produced Bigger Trees Near Warter for the Royal Academy summer exhibition in London, where it was first shown in May 2007, occupying the end wall of Gallery III.

[7] From 1 October 2011 to 4 March 2012, the painting was on display at the Cartwright Hall Art Gallery in Bradford, the artist's birthplace.
