Back on topic (though have enjoyed reading this post :D). I'd say yes you could grow your own veggies, but an allotment is a commitment in terms of time, energy, money etc. Why not try some stuff at home in pots, on windowsills, in the garden to see how you like it. Its amazing what can grow well in pots.
And as to "funky" have a look at the seed catalogues on line, there are so many varieties of veg, things you will never see in the shops or are hard to find, not even in Waitrose ;D. Black french beans, yellow cherry tomatoes, pumpkins and courgettes of every colour and shape. The list could go on and on, but I won't!
Oh, and welcome to A4A
