I was pulling a green weed from a hedge (photo may take a minute to load, for some reason the computer wouldn't let me reduce the file size):

http://home.kc.rr.com/badaboombadabing/DSC03190.JPG

Shortly after pulling out a bunch of this, I developed a terrible rash. :

It has been a month, the rash is gone, the weed is back (thats why I can give you the above lovely photo). I sent a picture of my rash in to a website to recieve a free informational poster about poison ivy. When I recieved my poster, the poison ivy in the pictures doesn't look like this plant. Now I am confused. Does anyone know what this is???? I want to know what I am from.

I don't know, but I have the same weed, and I get the same rash unless I pull it with gloves. DH is fine, no rash. Hrm...

Remember that what the Westerners refer to Poisin Ivy is totaly differant than that the Easterners refer to.

In the east it is a vine, in the west its not.

Dont reconize that plant but then I am a westerner

Just for reference, this photo was taken in Kansas. Which is in the Midwest of the United States. Interesting that Throk in Canada has the same rash giving plant. What is it? Anyone?

It doesn't look like eastern ivy though, either .. and we have both the ground plants and vines here.

Does the vine ever flower? I'm thinking it kind of looks a little like bittersweet nightshade, although it doesn't totally fit the description most books have of them.. Also reminds me a little of philodendrons, which cause major icky rashes on me and oldest DS .. My other question is, is the hedge a juniper hedge? Juniper can cause itchies too .. and REALLY fast - in under an hour. Ivy/oak/sumac usually takes 12-24 hours to develop.

It looks kind of like climbing false buckwheat (Polygonum scandens), except the flowers don't look quite right, from what I can see of them in your picture. Maybe it's a related Polygonum, or maybe I just can't get a good idea from that picture what the flowers are like. It's definitely not poison ivy.

Here's a page with pictures of climbing false buckwheat:

It doesn't match any of the things suggested so far

DH helped me make a zoom up of the flowering part.

http://home.kc.rr.com/badaboombadabing/poison4.jpg

I don't know if it would help to see the rash this plant gave me. Warning: The rash is gross!!

http://home.kc.rr.com/badaboombadabing/DSC03122.JPG

I had a severe allergic reaction to this plant! It is a mystery what it could be at this point. I really hope to find out what it is. Maybe then I could have a homeopathic physician give me some kind of remedy to make me immune to it. I have heard that this can be done with poison ivy. The poison ivy remedy wouldn't work if this isn't poison ivy though, I think??

I'm pretty sure that it's a Morning Glory of some kind (wild). Are you sure that the barberry thorns didn't actually give you the rash (the purple shrub) and not the vine???

OK-- I spoke too soon, without looking at all your pics (including that nasty rash, ick!!--that's what my dh gets when he touches poison ivy)

The vine in the picture is definitely NOT poison ivy--in vine or shrub/groundcover form, poison ivy always has groups of 3 leaves joined together before the vine or stem.

It may be a morning glory of some kind (Ipomea) but the flower bud doesn't look right to me. Then I was considering whether it might be a hyacinth bean (Lablab purpureus) or scarlet runner bean (Phaseolus coccineus), but the flowers are white, right? That would rule both of those out--and the stems don't seem to have a lot of color...I'm stumped...

It doesn't look like nightshade to me, either. Regardless, I'm still wondering whether the barberry got you and not the vine...

The flowers are white and do not look the same as morning glory, but the vines look very much like morning glory. I think looking in the morning glory family is going to put me on the right track. Isn't morning glory toxic? Toxic to me anyway. What do you know about the barberry giving rashes? Tell me more.......

The day or two before I got the rash the only yard work I did was to pull the vine out of the shrub. I piled the vine into my right hand, and carried it into the house. The vine rubbed against my right arm right where the rash appeared the following day or so afterwards. I did touch the barberry, but not as much because of the thorns. I say I ask my dh to chainsaw both of these plants outta there!!! If it was the barberry we could rename the shrub the GWBush

Does it have a smell when you pull it off? I have a vine/weed that looks like that, that has an odd smell after I pull it off.

Almost a little milky/moist looking when it is pulled and sweetly foul smelling...maybe that is what causes the reaction?

Also, this particular vine/weed has just appeared and started growing like crazy in the last 2 weeks.

That weed is definitely some sort of ipomea. My husband and I both think it is a type of bindweed. The leaves, the vines everything just look like a bindweed.

But we were stumped about the severity of the rash.

Now here is a REALLY crazy theory.....is there poison ivy on the property??? Could an animal have walked through the PI and then around your garden? Could you have picked up some PI oils from an animal? I have heard of folks getting PI from petting thier dog after the dog has been in it. It just takes a VERY small amount of oil to cause a rash.

Honestly, the barberry 'rashes' that I've gotten are more like reaction to being pricked by the thorns (sort of like a juniper rash). It only occurs exactly where you've been stuck and you get a little red bump or pimple where each thorn touches the skin--nothing like the chemical type of rash you got.

Different people are allergic to different things, so you never know. I'd take a piece of the plant (with the flower if possible) to a cooperative extension agent and see what they come up with as far as ID--there are a lot of different Morning Glory vines around, so it may take some work to figure it out.

I have definitely heard of people getting poison ivy off their pets, so that could be part of it, if you have a pet (as Chanley mentioned). Good Luck, and let us know when you do figure it out...

Hey, I think this might be it - honeyvine milkweed.

Check out these pictures and descriptions:

http://muextension.missouri.edu/expl...nemilkweed.htm

http://www.ppws.vt.edu/scott/weed_id/ampal.htm

Apparently it's often mistaken for a bindweed or morning glory, because the leaves are very similar, but honeyvine milkweed has opposite leaves (the leaves are in pairs, directly opposite each other), and the morning glories have alternate leaves.

Great job, Daf!!!

Cool to know. The flowers ARE atypical of a ipomea, should have sent up some flags. That is awesome!

Still does not explain the rash, but I am sticking to my contamination theory. Cause that is more than just a common ole garden irritant rash. Holy cow, blisters like that!

Daf, YES!!!! I think it is the honeyvine milkweed. It is a perfect match. That was some super plant sluething :

On the poison ivy/dog theory. We did have some poison ivy on the property, in the backyard. DH weedeated it to the ground over a week before the rash happened. We do have a miniature schnauser which is a small dog. I thought that it must have been the honeyvine milkweed since the rash started the day after pulling the weed, and it was right on my arm where the weed touched. The only way to know for sure would be to pull the weed again, if I did not have a reaction, then we would know it was poison ivy from the dog. :

I am going to avoid this honeyvine milkweed, and see if I can get a remedy to make me immune to it. Maybe I can do that for poison ivy at the same time. This way I will get an immunity to both. I hope to never get a rash like that again!!!!

Ahh...a milkweed.

It looks a lot like what i have growing. In my previous post I had asked if it secretes a milky substance when pulled. That is what happens when I pull these up. It might be the milky substance that you react to. That rash is horrible!

Armonia,

Since it has been over a month, I cannot remember if it excreted a milky substance or not. I don't remember any smell, other than the "I just pulled up some weeds" smell.

Does the substance in milkweed have a reputation for giving a severe rash?

ew ew ew... I'm so sorry to see that rash My husband gets *horrible* poison ivy, and it looks just like that. In fact, one mild winter he had it nonstop from March one year to November the next year - 20 months nonstop. The pets bring it in regularly, and deposit it on the backs of his legs when they rub against him.

The advice from PPs about the vine in question is very good, and I won't pretend I know anything more about that But, I'm willing to bet the culpret was the poison ivy your husband destroyed. You phrased it that he "weedeated" it. Do you mean he used a weedwacker? Bad, bad, bad ugly mistake. My husband did that once, before I had the chance to warn him of the folly... weedwackers spew shredded plant bits *everywhere*. And the oil (urushiol) that causes the reaction is very tenacious - it'll remain on the surface of dead plant bits for a long time, laying in wait for a hapless victim.

The rash takes a couple of days to develop. My husband finds it takes approximately two days after exposure to develop the rash. I'm willing to bet that your rash was poison ivy from your hubby's eradication effort. It might have been deposited on the vine you were pulling, or any other plant or gardening implement you were using.

So, never ever weedwack poison ivy!!!!! If you only have a little bit of it, put on plastic gloves and long clothing and pull it out of the ground. You'll have to do this several times until you succeed in killing the roots. Do *NOT* burn the vine - you can end up with the rash in your eyes and lungs, and you can die from that.

After three years of battling our literally acres of poison ivy, we finally gave in and started using non-organic means against it. It went from a question of organic gardening to a question of health care. We came to the realization that eradicating it once with Ortho would ultimately have a lesser impact on the earth than my husband having to take (and pee out and so forth) steroids for the severe rash several times a year forever. We felt seriously guilty about that until we heard from a friend, who has a PhD in botany and is a die-hard organic gardener, that Ortho's Weed-B-Gone is one of the least harmful herbacides you can use. It's very tightly targetted and it breaks down in the environment very quickly. With his seal of approval, well, we now only feel a little cheesy. However, I will only recommend that if you have *way* too much to reasonably pull by hand. Even at that, if it's a lot but manageable, you can cut and treat the exposed stems individually and never put it into the soil at all. I've heard of two different methods for this - painting it on with a paintbrush, and putting the stuff in a soda can and putting the cut stem into the can, taping it in place and leaving it there. I've had luck with the paintbrush method, but I'm not kidding when I say we have acres of it. I spent an entire day and made it through one garden bed, which was maybe 1% of our total poison ivy load, and 5% of the most dangerously, publically placed poison ivy...

Hey! I am glad to see you have an answer I was going to guess some sort of Morning Glory too, as many of them are noxious.

I did find This picture that looks remarkably like your rash. Here's the text that goes with it;
Quote:
caused by furocoumarins, a chemical found in some members of Apiaceae (including the Angelica atropurpurea specimen on the family ID section of the final!). The furocoumarins themselves don't cause a rash, but instead render the UV protective properties of your skin useless, resulting in blistering burns when skin is exposed to the sun (such as when your instructor continues collecting plants for 2 hours on a sunny day after accidentally dripping Angelica sap on his arm
It's from a biology class, obviously! I read about furocoumarins in several places. One was a lady who had a rash like that who touched cow parsnip. Here is a link to more info. It also says that weedeaters are terrible for people with this allergy.
Hope your rash is better soon!

Wow Serene,

Yet another excellent theory. I was out in the sun the whole time surrounding before and during getting the rash, taking my kids to the pool. I didn't use sunscreen because I had a base tan. It makes a lot of sense that the sap of the weed could cause a loss of protectant from the sun, which would explain why the rash looked so much like a burn. Except poison ivy looks like a burn too.

I told dh about the weedwacker problem. Duhh! Of course the weedwacker is only going to spread tiny bits of the stuff everywhere! We don't have a lot of poison ivy. There was a small amount of poison ivy mixed in with the rasberry bushes in the very back of the yard. Now of course I refuse to touch the weedwacker, and I haven't mowed the yard either since the rash happened.
