What are these plants/ trees/ flowers?

I have been cleaning out my back yard and want to make sure there is nothing poisonous and identify various other things.

Yard 14 is a vine with 3 leaves on each point, making sure not poisonous.


Yard 13 is a bamboo like bush, took pics before of them dead (hollow red stems in winter) just want to make sure they don%26#039;t spread.


Yard 8 and 6, have no idea, weeds or poison oak/ivy?


Yard 5 is pretty little blue flowers


Yard 3 has huge (same size as hands) leaves and thick smooth stem, very tall growing in few spots in yard, typically shade.


Yard 12 very tall like Iris%26#039; (happens to be in their bed) maybe peony? just started to have bud a few days ago and now huge bud showing


Yard 9, 7, 4, 2, %26amp; 1 poison sumac?, growing all down one side of my fence


Last 3 are of a tree, I took a picture in January (last pic) and no one knew for sure, now it has leaves and these cute little 5 point purple flowers.


Appreciate any help!

FlowersBirthday FlowersSympathy Flowers13 is an invasive non-native plant that should be removed and destroyed. It%26#039;s non-poisonous.





5 looks like spiderwort - a native species to US, non-invasive and worth keeping around. I have it growing in my front yard. No problem with spreading.





8 looks like the invasive tree of heaven or black walnut.
Reply:I only recognize #5 which is spiderwort, a pretty perennial with a blue flower. It can be invasive and will pop up in unexpected places.





#12 is a peony.
Reply:Yard 12 is a peony.


Yard 5 is an invasive but pretty wild plant (spiderwort)





Several others look like weeds to me.super nanny
