Leaves of three...

... but maybe not poison ivy? These would be large for PI, at least on the ground. What is it? Maybe Jack in the Pulpit?

 

Smaller brethren, same corner of the yard.

 

Trillium?

 

Trillium I see here has a variegated leaf.
Is that ivy pic some kind of joke? I could post ivy pics that would stand your hair on end; I'm talkin' waist-deep and thick, not a couple of grounders with three leaves. I could cut this stuff for kindling!

 

Yeah, we had arm-diameter vines on many of our trees, when I moved in three years ago. I killed all of it, at this point, so all we have left is ground creeper stuff like this.

 

I'd have a tough time eradicating it from my entire woods. It is almost everywhere to some degree. Hard to say how much different it would be today if I hadn't let them log this place twenty years ago. I have to think that when the Ash Borer gets here, the understory will bloom with more available light, and quite a few Oaks have gone down with the droughts and what-not. There is one ridge where there's almost no underbrush at all; I love going back there...
