Postbag Edition: Barbican

What vegetables could I grown that aren't native to the UK? Are there any punk-ish plants that thrive in a hot and humid room? Which plant would make a great building structure?

Peter Gibbs and a team of gardening experts explore the various locations of the beautifully brutalist Barbican Centre in London, all while digging into the GQT postbag to answer your gardening conundrums.

Joining Peter are ethnobotanist James Wong, garden designer Juliet Sargeant and Head Gardener Matthew Pottage. Leading them around various locations is the Barbican Centre's Head Gardener Marta Lowcewicz.
