Terrible reaction, as bad as rolling around in poison ivy. I wonder if this is the root cause of my allergy problems? I don't know if everyone is sensitive to it like this, but I think I'm going to use an herbicide for the first time in my life. Do not plant this in your yard!

This is invasive worldwide!
There seems to be a lot of confusion with Baby's Breath
Gypsophila paniculata L. which may also be invasive.
We have entire vegetable growing fields that fill up with white top, remain untended until fall and spread this weed even more which causes additional use of herbicides!

Like the other poster, it took FOREVER to figure out what this was. My sister and I have been searching online off and on for two days now!
Today we finally were able to narrow down to a hunch that it was in the Asteraceae family, then we found a site that listed the Parthenium genus plants. Voila, we saw a photo of False Ragweed, but the photo wasn't very good. FINALLY, we did a search and found it was listed here on Dave's.
Thank heavens for this site. It was beginning to drive us nuts!
Thank you everyone who posted pictures of it, too!
For us, we had no allergic reactions. We have been handling them quite a bit these last few days, so if we were going to we'd be in pretty bad shape as much as we've handled and sniffed, etc.
I'm wondering if perhaps the Texas variety is not as noxious as the ones elsewhere...?
I'm in Spicewood btw. I think my membership here says Brownwood, but I've moved. Spicewood, TX is outside of Austin.

This spring I had about 6 seedlings to come up near where it was planted. I removed them and planted them where I wanted. It has tiny white pentagon shaped flowers and the large plant is covered in the tiny flowers causing it to look like Baby's Breath at a distance. Apparently, Im not allergic to it. It is care free in my garden and fits well with my plan of xeriscaping.
Im wondering if the Negatives posted here are referring to the same plant! There is real ragweed which causes terrible allergic reactions. This plant does not seem to do so. Real ragweed is of the genus Ambrosia and there are many species of Ambrosia ragweed.

(Homeopathically, it is used as a medicine to cure such problems). It has the great ability to reseed. It is said that it appeared in India somewhere in the '70s with American wheat that India imported. It later spread all over the country and was a major problem in agriculture. So invasive it is! Scientists had found that a particular beetle was fond of its leaves and they had left them in areas where it was to be eradicated. It worked but that beetle began to eat away other plants and that was withdrawn.
