Trees for a shady border?

[Pannacotta]

I need to find a tree to go in a shady North facing border.
We already have a tall Holly and Laurel there and I'd prefer a deciduous tree, ideally which has either blossom or berries/autumn colour.
Most tree info I can find only lists for partial shade, are there any good garden trees which would do ok in a North facing border? Can't be too tall/dense.

TIA

Anyone?

morello cherries, autumn bliss raspberries, blackberries, apple trees.

lovely woodland plants can go underneath for spring colour (primroses, forget me nots, wild strawberries, wild garlic).

depends on whether you mean north-facing or/and in heavy shade?

*in really dark corners fruiting trees/bushes won't really provide colour/fruit - then look for verigated forms of popular bushes. or trees that change into dramatic reds/colours.

Thanks casbie.
The border faces North and is pretty shady in the spot where I want to plant a tree.
Have lots of groundcover ideas, but decent sized trees are harder.
There is an apple tree already so am looking for something to plant next to that.
Didnt realise cherry trees woudl grow in shade, or did you mean morello shrubs?

amelanchier? one of the pretty oaks?

I love Amelanchiers but they flower at the same time as apple trees so dilutes the effect a bit.
NOt sure about Oak, am not very familiar with them, which ones are pretty/not too big?

Dogwood? We have one in a farily shady dry corner & it seems very happy.
