Identification of Perrenials?

Just bought a home in central PA. Plants in the yard are unknown to me. If you can help identify them, i thank you in advance.

#1 - #5

 

1. Peony.
4. Resembles Toona sinensis

 

3 reminds of Alliaria petiolata -- squish a leaf between your fingers (wear gloves if you are concerned) and see if the smell resembles garlic.

 

thanks...i'll try the pinch and smell test and report back

thanks...i probably should've known #1 was a peony...but i didn't...
there are loads of them!

 

Last one is a lily and a peony. The second one looks very familiar. I think it will be easy to ID once the flowers open.

 

Thanks Eric
