Hardy Geraniums - help with names please

I have lots of hardy geraniums in my new garden, many of which must be self-sown, and I do like to know what things are, so any suggestions welcome.

1. Pink stripy - G. endressi? I have some where the flowers fade from mid pink to almost white, and some that stay a rich candy pink.







Some have larger flowers than the others - does that mean that they might be a variety, or are they just stronger growing?

2. Small purple flowers





3. Larger purple flowers





4. Blue - G. x magnificum? Has very different leaves.



6. Large magenta with black centre, on a large, lax plant 1m x 1m plus. - G. psilostemon, or variety?



7. G. macrorrhizum, but is it the species, or a variety?





Sorry to post so many, but I though those of you who, like me, are hiding indoors from the heat of the day, might like something to do!

 

I think the second could be Wargrave pink but there are so many similar pale pink varieties.

 

I also have a ton of them. thinned out a bunch last year, and this year. still they are huge .mine are just the simple ones. a great tough plant. I gave up long ago to trying to remember variety names of stuff, too much.
