will produce artichokes a lot better in a sheltered spot. Their most
favoured habitat is in the Mediterranean region, but they can grow and
produce quite successfully in UK if given the right care.

The one seedling I planted on my allotment, far from sheltered, died
over winter.
If any of this years plants survive, how do I know when to pick the
