Cotoneasters do not really enjoy drastic root pruning, they are very tolerant of bad soil conditions though. The horizontalis that Joe suggests are great, very easy to look after and propogate, the leaves reduce really well and it is not too difficult to get them to flower and fruit.

If your interested in the cotoneasters then also look up Wardii and Microphyllus. These are two gems of the family.
