If you ever get the opportunity to visit the walled vegetable garden at Heligan in Cornwall, don't miss it. A couple of years ago I visited in the Autumn and found a discarded dwarf bean plant on the compost heap. The temptation was too great, so a couple of dried pods found their way up to London. An old purple variety called "Royalty" - very prolific. I have been saving seed this week, hanging up the old plants for the large seed pods to dry.
I made a large batch of ratatouille today. Peppers, courgettes, aubergines and green beans, thyme - cooked together with tomatoes and onions. Veggie Heaven!
