There's almost not a speck of green space to be seen around Commercial Street, unless you know where to look. And that’s on the roof at much-loved pub The Culpeper, where it grows as many herbs and vegetables for its menu as it possibly can, alongside its greenhouse dining room and its wood-fired grill. And what can you grow in the depths of the city, do you ask? We’ve spotted courgettes, radishes and radishes. And if you’re green-fingered yourself, you can take part in gardening workshops up here, too.
