what about some of the slower growing conifers. I like Pinus mungo, something going on all year with it.

That's a really good idea - actually it's a brilliant idea. :)

I've had it for 16 years and recently had to dig it out but I am replacing it.

How about a Corylopis the foliage is stunning and coming into spring nice small lemon flowers.

New to my garden 7yrs ago and love it its slow growing.

I have just had a quick look on crocus and the corylopsis they have looks lovely. it is so hard to decide!!

I so love watching my Corylopsis its really lovley .

Or a witch hazel Diane would also be nice.

Good luck on what you dicide.

I have a cotinus [Grace] as a feature shrub, not evergreen but so lovely in Autumn as the leaves go red. Purplish leaves in other seasons.

japanese maple for me. I know they don't like the dry but if you water until established, it should be fine.

How about a standard trained camellia. Choose a williamsii one eg Donation.

Amelanchier - 'Ballerina' or 'Obelisk' would be the smallest.

Thanks everyone - I shall have a look at all those suggestions :)

Amelanchier are lovely. So is the Judas tree (mine is in a spot like yours) Cercis siliquastris I think!

Mahonias are possibly a bit big, but they are evergreen, have delightful, scented winter blossom and do very well in total shade.
