I would ask the home owner to please identify them. The owner may also expect certain things to be done when the plants look like this so ask the person what to do with them. The person may have emotional attachments to some plants so it is best to get plant identification and marching orders from the home owner.
Walk thru the garden with the owner and a notepad. Take notes as the homeowner explains things or even record the conversation with a smartphone so you can more clearly reference what was said on that day. If recording, identify the plants and mention where you are located in the garden so, afterwards, you can follow the path as walked just as you did on the day of the recording.
Writing notes sometimes does not work. I have been known to take written notes and then not understand what I wrote down. For example, right now, I currently have something on my grocery list that resembles the words "yellow tip soup" and I don't have the foggiest idea what in the world that was, could be or what did I actually write down. Oh, Lord! ;o))
But the pictures are too far away to hazard a guess of what the plants are. The first one reminds me of an out of control rosemary bush(es). I cannot even clearly see the foliage of the second one. Looks like it has some green leaves along with other reddish ones or maybe there are some reddish, leaf looking flowers at the ends of the branches.
