zone 8, north central Florida --- growing wild.

Ann, sure looks like it to me. There is an old saying, the first part I can't remember (which refers to Virginia Creeper), but the last of it is "leaves of three, let it be," I have the stuff popping up all over my yard this year and have to be careful not to get too close to it as I am very allergic to it.

Well, I was pulling some Virginia Creeper off that tree trunk one day & I grabbed this stuff b/c it was on there too & I pulled one line off & then went WHOA! Uh Oh --- leaves of 3...... hmmmmm... wonder if this is poison oak?
I have tromped the woods all my life & never gotten a case of poison oak or poison ivy & I'm 55 & I've never paid any attention to what I was touching. I figure I MUST have encountered it somewhere at some time. Anyway, I've never learned to recognize the stuff. But with age comes caution & now I'm afraid to touch it for fear of suddenly having developed a sensitivity to it.
And I thought if this is poison oak then I will put it in the db as it is not there presently.

3 leaves, red stem: it's definitely Toxicodendron.

The lobed leaves further say that it's poison oak.

Thanks Dave. And YIKES!

Would you say I should put it under Eastern Poison Oak?
I was just reading up on the stuff & everything I read says it mutates leaf shape to resemble the plants around it so how would one ever tell exactly which it might be?

Look at the young plants of Toxicodendron radicans bottom left .. they look like your young plants.

Well, that is truly eerie. I guess I have poison ivy. Gee, and I thought it was oak. Crud either way.

Thank Janet!

The photos Janet provided sure are poison ivy but I don't think they are a match with your photos. Your plant shows much more deeply lobed features than any poison ivy I've seen.

I'm still thinking it's poison oak but I admit I could be wrong on that.

Due to the uncertainty, I wouldn't add it to the DB until we can get confirmation.

Check out this photo of young plants of Toxicodendron radicans, and compare with Ann's similar photo. That's from an education site but I guess it could be wrong.

They are both the same genus and both seem to be variable. Some drawings suggest poison oak, but most photos I find don't.

Okay, I found these 3 sites for Florida in particular which show some good photos & give good info. Honestly, I keep see-sawing between oak & ivy.

I have a friend who is taking photos of their poison ivy in Alabama. The husband there says my stuff is poison oak IHO.

Now that I've had some education on the subject; I will study & take more photos next time we go to the property. I'm not as afraid now as I walked all through the stuff the last 3 times we were out there & logically from all I read, I would have the oil on my tennis shoes which I have been wearing since then & I'm okay. Furthermore, I am not sensitive to Mango nor to Schinus terebinthifolius aka Brazilian Pepper. I never knew until today that Brazilian pepper is in the same group & contains urushiol.

There was no sign of blooms when we were there Saturday. I will keep looking as that will give us the best clue.

I will not add this to the db until/unless I can be sure we know which it is.

Grandson is covered with blisters from pulling weeds at their new house. My DD showed me the suspected plants today. Could this be poison oak? I read through all the above links that worked. The only photo that resembled it was: Toxicodendron pubescens

It's growing under a large oak tree that is surrounded by a three ft wall. I thought it was just a tiny oak.






Hope it's not poison oak, but if it is, we'd like to find a way to eradicate it without harming the tree.

Poison oak

Re climbing poison oak...
Poison oak isn't supposed to climb.

But the leaves sure look like poison oak...

Re eradication....
Poison oak isn't difficult to shovel dig.... At my house, the roots generally run parallel to the surface of the soil.... An inch or so down...

Maybe do some watering first...

Thanks, Stone! I'll pass that along. I'm not getting near it.
