Hi Louise - have a look at Gardening with Conifers by Adrian Bloom http://www.amazon.com/Gardening-Conifers-Adrian-Bloom/dp/1552096335
you'll have more options than you dreamed of.
I bet Verdun will come up with some great suggestions too
Sorry, my link shows the USA site, but Adrian Bloom is an English gardener and the book is available in the UK.
