from my garden zone 8b we filmed this in mid autumn, to show the results of summer plantings.
My favourite is spinach "Medania" sown 10th August which crops through autumn, then goes semi-dormant in winter cold (we stay above 14-18F) before cropping heavily in spring, until flowering in June.
The are of garden filmed here is 16 feet square and almost everything you see was sown July & August, after harvests of onions, salads, zucchini etc.
