COTE JARDINS - What's the best option ?

Bonjour à tous et à toutes,

I am asking for help. 

In our home in Ré, there is some space alongside the wall in the terrace where 

there is a figuier and lots of bad green plants (weeds) which grow along. So, I asked a Garden Center to come and look at this space to have better plants and flowers.

My desires : Evergreen plants, with Hydrangeas
 or any other suggestions should be very helpful. 

I like Hydrangeas, and Buxus)

 but I have no idea if it is the right plant for the right place. 

Anyway, 

the garden Center gave me 3 options following my tastes. 

1 - Buxus

2 - Verveine de Buenos Aires

3 - Quercifolia blanches (I prefer the hydrangeas)

so with somes images from google

I tried to make some presentations, suggestions....

1 - Buxus + Verveine de Buenos Aires ?

2 - Buxus + Hydrangeas  ?

or 

3 - Buxus + Hydrangeas + Verveine de Buenos Aires ?

AS IT IS NOW ...

                                                      -                             

So I am asking you ? 

What do you prefer ? 

Any suggestions ? 

Bon Week End !
