This enclosed garden has all kinds of inspirational ideas for making a low-cost school or community garden in a small space on the north side of a building: willow spirals, rainbows of flowers, soft paths, and plants that are textured or spooky or scented.

Look out for carnivorous Venus flytraps, sweet scented marsh mallow (used to make sweets) and the squirting cucumber which bursts open and shoots its seeds eight metres.
