Poison Ivy Vine or Virginia Creeper Vine? Two Native Plants in NYS
Courtesy RIGC Member John Dougherty

There has been some genuine Poison Ivy spotted in the community garden and there is certainly some growing wild on island. But how can you tell if it's poison ivy or just juvenile Virginia Creeper, which looks very similar? Here are some tips on identification:
  • Poison Ivy has 3 leaflets per leaf. The two side leaflets are closely attached to the stem while the middle leaflet has a longer attachment.
  • (The stems are often red, too.) 
  • Some young Virginia Creeper also has 3 leaflets, but if you follow it back to the stem, you will find other leaves with 5 leaflets.
  • Poison Ivy has one or two deep notches on the side of each leaflet, like an ivy. And Virginia Creeper has serrations, more like an elm leaf.
  • Poison Ivy has flatter, veiny leaves; Virginia Creeper leaves are more pillowy.
​
Here are two examples of Poison Ivy.

Here below are two examples of Virginia Creeper. Virginia Creeper is a wonderful vine which is a host plant for pollinators. Many moth caterpillars feed on its leaves and in turn the moths help with pollination of flowers and vegetables in our garden.  It turns beautiful red colors in the fall.  It is easy to grow and easy to prune back if it gets too large.
