Who’s got the biggest green wall?

Is this a very male question? Maybe, but I was struck by the claims from the National Grid that their new car park green wall is the largest in Europe! Is our very own Madeira Drive green wall bigger and better?

The National Grid boasts “a living wall of 1027 sq.m, making this Europe’s largest. The Living wall is home to over 97,000 plants of over 20 different species“. Undoubtedly impressive stuff.

Madeira Drive’s green wall by comparison – planted by the Victorians along the East Cliff in c1880 – was approximately 20 metres high and 1.2 kilometres long when at its very best in the 1980s. 24,000 m2 in extent.

Now, substantially diminished with gaps where plants have died and not been replaced, the wall is – and I’m guessing here – very approximately a quarter of its former extent. Still 6000 m2 though!

Building Green and the Ecology Consultancy surveys have found 100 species of plant on the wall.

So sorry, National Grid – it appears our green wall is bigger than yours after all!

Maybe we need to amend the flyer now to say ‘The oldest and longest green wall in Europe!’.
