In shade, Aucuba japonica 'Crotonifolia', in sun, Choisya ternata 'Sundance' as long as its not a very exposed situation

Photinia red robin is a wonderful shrub with good colour & beautiful flowers and can be kept pruned.

Except Photinia gets a lot bigger than 6 feet...

Choisya does too if not pruned, same as any shrub, also spotted laurel can get out of hand if left unpruned.

Aucuba 8 feet, Choisya 5/6 feet, but I guess its up to Magga to check them out on google for herself and decide.

I am a huge fan of Euonymus japonicus 'Aureopictus' and E. japonicus 'Ovatus Aureus', both wonderful evergreen fully hardy specimens for the UK, which look like a splash of sunshine in your garden all year round. As I mentioned previously they are evergreen and will grow to a height of 5/6 ft and can spread as wide. It is easy to clip into shape if you don't want it to be that wide.

If you don't mind a deciduous shrub I recommend a (Mock Orange) Philadelphus purpureomaculatus, 'Belle Étoile'. Mine is simply stunning this year and the fragrance is simply to die for. As soon as the shrub had finished flowering, cut out all of the stems which have just flowered. Prune them back to around a third of their length. Every five year I cut it right back to about 3 feet. I know this will effect the growth the following year, but it seems to give the shrub a chance to regenerate. Be careful of aphids as they love this shrub, spray end of May beginning of June to them at bay. My Mock Orange normally flowers on my wedding anniversary in mid June, but we've had a late summer and it's 2 and a half weeks late.

I'm going to post a photo of mine as I am so proud of it this year. If you have a moment please take a look.

I hope you pick a healthy happy plant.

Susie.

Thanks everybody you are all so helpful and I am so grateful.
