hi all, this is my first thread 
i'm looking to choose two pears to be trained as verticle cordons either side of a 4m wide window at the gable end of our bungalow. It'll be sw facing, and although there is a 12' hedge 25 meters away and a couple of lower hedges closer we are still a little exposed as there are fields for as far as you can see the other side of the hedges. we're located on the hampshire surrey borders so reasonably mild.
I'm keen to choose fruit trees that are either not available/hard to find or have some historic value, as well as obviously being good to eat, fresh or cooked! . I already have a conferance which may effect the decision re pollinating partners
So..... what would you choose?
thanks
