To james hello and nice to here from you i am from the wirral next to liverpool. the trees you have said are all ok if you have been into it for a couple of years and do not mind a bit of failer but if you are wanting to get a few tree's that will live up to the english weather i would go for the likes of feild maple, trident maple , juniper sargentii or simalor juniper, silver birch, beech and elm's. the pomegramet is a loverly tree but the weather can do you no favers i had four grown from seed and was keeping a close eye on them no frost in the air mid sept and there was a cold snap one night lost them all. if you thinking well i would keep them in doors remember that most houses have got cental heating and it's a nightmare to try and keep them in conditions like that. look in B+Q for a chinese elm that looks crap the cheapest you can find and keep that alive this will give you something to look at and in ten years you will have a realy nice tree. try English tree's they are very nice and you are always able to pick up saplings from vereus locations
