|I have an invasive weed that can be about 2 ft tall with 3 leaves similar to poison ivy with a (june) flower at the top similar to Queen Ann's Lace - large cluster of small white flowers. Roots are tubular and if it is pulled it seems to then be stimulated to grow even more. In weeding last year , I and mh dog had a severe case of systemic poison ivy - I had never had this before. I am tempted to use Weed b'Gone and "torch" my perennial garden - but I would like to first identify the plant and second have a removal plan recommeded that will eradicate the plant and save the garden. Today a local garden store suggested that it may be a type of wild gingseng that does resemble poison ivy. My e-mai addresses are firstname.lastname@example.org and email@example.com Can you help me?|
|Based on your description it could be the unvariegated form of Aegopodium podagraria, although I am not aware of people suffering a skin reaction to that plant.
For reference, here is a link to a photo of poison ivy in bloom (scroll down on the left, it is the best photo I could find in a quick web search). The flowers are small and yellowish and not at all as showy as Queen Anne's Lace.
For a more positive identification of the plant, I would suggest you consult with your county extension. Based on that, they should also be able to tell you the best way to eradicate it.
It is also possible that the skin reaction came from somehere else entirely, somehwere that the dog had been and then you came into contact with it on the dog. I'm sorry I can't be more helpful.
