Hi there - well done with the photos !!!
First is, I think Acanthus Mollis.
Second photo looks like Leycesteria formosa - Pheasant Berry shrub.
I believe that both can grow quite large - we have the first in the garden and it is quite large - do not have the second but, coincidentally, saw one in the garden of a neighbour today and it was a good sized shrub - over a metre in height.
Hope this helps and I'm sure that other forumites will have other ideas as to identity.
Happy gardening
