Over here in the UK our allotment (plot size about 60x40 feet) has produced blackberries, broad beans, French beans, pumpkins, ornamental gourds, chard, beetroot, cucumber, zucchini, leeks, shallots, plums, pears. We started the year with some reasonable asparagus too. Our tomatoes down there (it's 6 minutes away from the house, below sea level) were rather pathetic probably because it gets quite windy, but our dahlia collection was and is fantastic. The only problem is the water supply, which is from cisterns so you have to water with cans by hand. Nonetheless very satisfying, and we did better than other allotment holders this year notwithstanding the late start (cold and wet), the burst of warm weather at the wrong time and then return to cold and wet!
