Evergreen suggestion

Dirty Harry

To the right of the fuchsia is where I'm looking for a flowering evergreen to go. I'm allowing for that whole area eventually, the foxgloves etc. will be getting moved.

I have bees and such like in mind so something that flowers in the winter is a must.

It'll need to be something that can tolerate full sun in the summer though. Was thinking along the lines of Mahonia 'Winter Sun' as apparently it can tolerate a lot of sun but it's fully grown size is a bit much, can it be pruned successfully to keep it in check without compromising on flowering etc.?

The wall is around 6ft high for a sense of scale.

Viburnum tinus was something else I'd thought of but I already have one in the corner of the garden and like to mix things up a bit. Could still be an option though.

Viburnum tinus ?
Large Mahonias are, IMHO best kept in check by removing whole stems to about 12" from the ground. If you do about 1/3 each year, you'll keep the height, but keep newer branches coming along behind.

Just as I finished editing the post.

It sounds like a nice protected area with the wall. You could try the Chinese Witch Hazel, Loropetalum Chinense Var. Rubrum 'Fire Dance'. Lovely deep purple/red leaves in winter time that tends to turn dark green in the summer. The pale pink flowers can start from as early as January right up to March.

Hello Dirty Harry. You could go for a Choisya (Mexican Orange Blossom). It flowers twice in the year and there is a nice golden one called Aztec Gold. Its height can be kept within the bounds you want.

I was thinking of that too Ladybird. They'll take quite a bit of sun and easy to keep tidy. They don't flower in winter though. 
Does it absolutely have to be winter flowering Harry? 
Daphne? I think some are evergreen. I don't grow them but someone will advise about that.

Dirty Harry

Thanks for the suggestions. I'd prefer winter flowering as there won't be much else in the garden for bees etc.

Take a look at Sarcoccoca (Sweet Box) then Harry. Its Winter flowering, evergreen and has the most delicious perfume.

You should consider Daphne bholua 'Jacqueline Postill'... it's very hardy, tolerates full sun, evergreen and blooms from late December to April...  rather slow to establish and must not be moved after... easily kept to about 6 x 5 foot after 5 years or so.. or taller if you wish...

I should supply a photo...

A winter flowering heather would attract the bees, we have a lovely white flowering heather that keeps the bees happy.  A Hebe perhaps or mix a few early flowering bulbs under the plants.
