Because the fence is south facing I chose a dessert pear cordon for one of the trees. I went for a Nouveau Poiteau pear on Quince C rootstock. The description is as follows: Dessert pear. Pick October. Use November. Flower Group E. Fruit russetted, flesh sweet, very melting, rich flavour. It should be fine for pollination as there are two other group E pears in the garden and a group D (althouth that one is a triploid). Hopefully it will enjoy the sheltered spot.
The other tree I chose was a quince cordon. This form for a quince doesn't seem very common but I am hoping it will be fine. I have another larger quince tree (Agvambari) at the other end of the garden which has been disappointing so far. The Agvambari is supposed to be self-fertile, but I am hoping the new cordon will help with pollination. I chose Serbian Gold for the cordon on Quince A rootstock. The description is: early ripening,, very productive, healthy tree. Sounds good.
Both trees were from bought from Agroforestry Research Trust which has a really good selection of trees that are well suited to UK forest gardens. Worth a look if you haven't already.
