This is one of several areas of allotments in Edinburgh - they are usually hidden from view but you get a good look at them from the railway line cycle paths. As many people don't have their own gardens, these patches are in huge demand, and some of them have waiting lists of up to seven years!
P.S. This post is dedicated to my mum whose birthday it is today! She's got green fingers and although she doesn't really grow vegetables she has somehow managed to cultivate a fig tree in the front garden.
