\n<\/span>Climber<\/span> seen by the road side<\/span> in New Jersey<\/span> during my visit in June 2017.
\n<\/span>I was given to understand by my friend that this was <\/span>Poison Ivy<\/b>.<\/span><\/p>\n<\/div>\n

\n
\n
\n
yes, Toxicodendron radicans<\/i><\/div>\n
eastern climbing poison ivy<\/span><\/a><\/div>\n
look at the thin hairs that cling to the host tree<\/div>\n
This is their summer color<\/span><\/a>, prolific in growth, and widely available all over, you cant miss it.<\/div>\n
in the fall they are spectacular red\/orange\/mottled\/\/look attractive to those that do not recognize it<\/div>\n
and they want them for the fall\/\/thanksgiving decoration!!!!<\/div>\n
Leaves can be highly variable<\/span><\/a>
\n<\/u><\/div>\n
its a horrible plant<\/div>\n
read this if interested <\/span><\/a><\/div>\n
there is a rhyme for it to remember:<\/span><\/a><\/div>\n
There\u2019s a saying to help identify Poison Ivy\u2026<\/span> “Leaves of Three, Let it Be!”<\/span> <\/b><\/span><\/div>\n
\u00a0<\/span><\/b><\/div>\n
==<\/b><\/div>\n
for sake of completeness<\/span><\/div>\n
there is <\/span>a western poison ivy <\/span>Toxicodendron rydbergii<\/i>,<\/span> <\/span><\/a><\/div>\n
not so prolific and common, even in the west, one has to search for it<\/span><\/div>\n
it does not climb, grows on ground only<\/span><\/div>\n
I have seen one. near a railway track after much searching once in a somewhat wild ernes place.<\/span><\/div>\n<\/div>\n<\/div>\n
\n
\n<\/div>\n
\n
Thanks a lot. I knew you would give your valuable inputs to this post. Had seen one at New Windsor also. It was growing through the wooden strips.<\/div>\n
Will post it separately.<\/div>\n
And thanks for the additional information as well.
\nYou are too good with US plants.<\/span><\/span><\/p>\n

This was the other what I believe to be Poison Ivy<\/b>.<\/div>\n
It was deep in the woods, coming out of a wooden platform.<\/span><\/div>\n
We had stayed in an airbnb. It was a wooden house in the woods.<\/span><\/div>\n
Taken in June,17.<\/div>\n<\/div>\n
