Hello and welcome!
We have a really tiny garden too, just a 'drying green' really, but we grow quite a lot in pots and sacks. We do have a front lawn too, which doesn't get any sun until about 3pm in the height of summer. I grow kale and PSB in the front. In the back we have done spuds in sacks (more for fun than huge crops), salad leaves, chard, courgettes, climbing beans, dwarf beans, various herbs and carrots, all in pots.
The children love joining in, too.
There are some great books about container gardening - I really like Michael Guerra's book 'The Edible Container Garden', and pots are easy to come by on Freecycle.
Are there any community garden / landshare schemes local to you? If not, maybe you could find some likeminded locals...
