The artist Luke Jerram on the tree-planting project he’ll never see finished

It may be a midlife crisis, says the man behind seven-metre installations of the Earth, moon and Sun who has planted 365 trees in a 100-year project in Somerset

Luke Jerram, whose art installations have travelled the world, is philosophical about his latest project bearing fruit beyond his time on Earth.

Known for his Play Me I'm Yours street pianos project and his Museum of the Moon artwork - a seven-metre diameter sculpture of the moon featuring detailed Nasa imagery of the lunar surface - Jerram is now working on Echo Wood, a living, breathing installation made of native British trees.
