Nottinghamshire,
United Kingdom 
I have an idea to plant a border dominated by "holly-leaved" plants such as Mahonia, Desfontainia and Osmanthus. Apart from these and the already planted Quercus Ilex does anyone have any other suggestions? Thanks in advance

Osmanthus ilicifolia(heterophylla these days). Indeed look out for any plant with the name 'ilicifolia' as that means 'with holly like leaves.'

Have you looked at all the different varieties of Ilex? Variegated, prickly, non-prickly, big leaves, small leaves, berries, no berries.....loads to choose from.

There's also itea ilicifolia with long catkin flowers in summer

Olearea macrodonta is a good one too.
Reminds me, I must get some cuttings of the huge Desfontainea at work!

or even Olearia!

It will make a nice and unusual border. Remember that 'holly' leaves are prickley so weeding and tidying will be more challenging.

Check out Berberis varieties, such a B. darwinii - very small leaves, but definitely holly like
