What plants are these?

I'm beginning to redo our garden and need your help with identifying existing plants left over from the previous (now abandoned) ornamental garden.

#1: Campanula, probably poschkarskyana
#2: Lotus (scientific name) from the fabaceae family (there are no "weeds" in my book: most of these plants are even considered medicinal herbs)
#3: probably acanthus
#4: probably some species of thyme
#5: yes, geranium, they come in different sizes and forms
#6: probably golden rod
#7: could be satureja or thyme
#8: coreopsis?
Not sure about the next two. Have you tried one of the Apps to identify flowers, like Flora incognita?
I have heard they are pretty good (from people using them in Germany).

No. 9 could be oenothera perennis, but I have never seen it with my own eyes so I am cautious...
