#1. Yes that's it for sure
#4. I'm not sure the leaves don't look the same to me

 

#2. I thought it looked slot like cushion spurge. But this one spreads a lot. Any idea if what type of euphorbia it is?

 

Cypress spurge (Euphorbia cyparissias)

 

Thanks

 

#4. Thalictrum aquilegiifolium.
#5. Chrysanthemum, as noted.

 

Thanks, I cant wait to see what colour #4 will be, and yes now that I googled medow rue, there is a type that has the same leaves, thanks so much, cant wait to find some more good ones for you guys.
