A few evening’s back, we went out to Sheldwich to see the field known as Church Plantation, with its dazzling crop of echiums. We weren’t the only people drawn to the improbable spectacle of blue, pink and white flowers, with its thrumming of bees, a young couple parked up and staging photographs for their Instagram accounts. We got there late, the sun all but gone, which meant the echiums were kicking out an almost neon-like glow, their green stems making for welcome contrasts, and the white echium flowers smattering the rolls of blue waves like foam.
