Choisya looks like its suffered, possibly during the winter. Depends how long you want to wait for it to grow back, if it does so you can either hack it back and wait, or dig it out and replace.
Can't really tell what the shrub next tier down is, not close enough, but I suspect it may well be some kind of Mahonia - need a pic a bit nearer to be sure.

What an interesting looking garden, Titchy. Are these a series of raised beds?
I fear that the Choisya might be dead but if you can bear to leave it for another month or two, you never know.
It is difficult to see the other shrub clearly enough to give an id. Does it have holly like leaves? in which case it could be Mahonia.

Wow, talk about 'great minds' Bamboo, we posted at the same time.

Thanks to both of you, I think you are correct, the minute I read Mahonia, I remembered someone told me that before it was moved, so I'll be able to read up on it. Bulbaholic you have not read my blog, not very good but it's about "From the North Face of the Eiger to a terraced garden" I think you can find it under the sloping garden ideas. Anyway thank you both

wear you find green there is a possability always.

Thanks Noseypotter, that's what I thought, hate being ruthless, so I might put up with the look

i would i dont think a garden is ever finished so theres always somewear you dont think is as nice as it could be so if thats the case its just part of the bigger picture .lol i can talk for england if you hadnt noticed .

You'r telling me NP, just came in from digging right at the top of the terraces, and I am litteraly knackered. It's going to take me ages to complete this back garden,(as you so rightly say it will never be finished. The landscapers were good but there is so much more that needs doing, All the little corners that have been overlooked. Well let's be honest it needs a woman's touch.

everything does im not sweet talking but i do believe behind every great man etc but not the other way round i dont think.look at margerate thatchers husband lol.ive just been putting a cement frame round some glass painting .i do outside pictures .its been needing finishing since last summer . i got the buzz for it now lol .my back is killing me .gardens are never finished.i dont honestly think if you had a garden that you never had something apart from cutting the grass and weeding to do in youd give up . well i would . i think they morph more than actualy get finished.then again i am insane lol .
