I was very surprised to find this plant On the edge of the lawn outside one of my flower beds. No idea where it came from. It's not liste...Read Mored in the Eastern Edition of Peterson's Wildflowers of Northeastern/North-central North America, but I did find it in the Southwestern and Texas edition. Sure didn't expect this plant to show up in New Hampshire!

everything I have read about this "weed" is negative. I have one in my garden and was curious about it so I posted it on facebook and one...Read More of my friends identified it. I live in Ohio, so I am surprised to see it is mostly found in the southwestern United States! I planted watermelons in my garden this year, (a first,) and the leaves look IDENTICAL to that of the watermelon, except for the yellow flowers and the thorns, I would have left it there thinking it WAS a watermelon! needless to say, I pulled it. (carefully) but I am trying to figure how this thing got in my watermelon seed pack I bought from LOWES. My only conclusion is the package says it is a "product of Mexico," so seeing as where it is Native, I assume this was an accident..

I rarely give a negative to any plant but I just can't find any redeeming qualities for this evil plant. We always called them bull nettl...Read Morees/stinging nettles around here, but those are actually different plants and are very edible and nutritious. The buffalobur/cocklebur has barbs on its thorns like a fish hook. I think this monster is the reason behind the dinosaur extinction.

Note: Audubon Society says this plant is "Highly Toxic" (see below)

My wife and I first noticed this plant in our Lynnwood...Read More, Washington yard about 3 or 4 days ago. I took a picture of it, because it was so unusual looking. I sent the picture to a friend. In discussing it, I decided to look it up in my "The Audubon Society "Field Guide to North America, Wildflowers, Western Region." Color plate #210, informational text, page 790.
Further research lead me to this web page. The only reason I am commenting is that the Aubudon Society warned highly toxic and some of the people who commented on this web page seemed to have an interest in cultivating this invasive/toxic plant. (And I intend to cremate this plant, but not in a BBQ that I cook in! This thing just showed up-have no idea how it got here, have never seen another one before!)

I have never seen a plant with thorns on the top of the leaves (big thorns, at that)! Two of these came up in my flower garden in Chico,...Read More California, this spring and I let them grow until the seed pods (resembling gooseberries) formed. None of our nurseries recognized the plant, but the State Agriculture Department office was able to identify it for me. No one can explain how it got into my garden.
