Plants Plants Plants

Well because I can't sleep, I'm going to post some plants pics....how's that?
Ok the funky tree has a name cutleaf stagehorn sumac...thank you Neil!

So let's start with the unknown ones. This one is another one that has been bugging me. I live in zone 4 remember. I swear it is bamboo. So does my neighbor, so I'm not nuts!

Ok then's this plant/weed.

And then this one I finally identified! Virginia Waterleaf, thank you very much! Of course now mine in not in bloom, but it has the most delicate little lavender flowers on it.

Last one, another unknown, I'm pretty sure they're a flower, just don't know which ones.
