Comments

This is not porcelainberry. I hope you're ok, because the plant you found is poison ivy.

It's important for you to recognize this plant in the future, to avoid the problem you now have ... itchy skin, blisters ... Here's how to tell poison ivy from other plants:

1-Poison ivy is a vine. Sometimes its stem creeps along the ground and the leaves stick up (this is what your plant looks like).

2-Poison ivy's leaves are compound (that means they have more than one flat part). Poison ivy's leaves always have three flat parts (they're called leaflets).

3-A few other plants in Maine also have three parts. One is green bean, but that's always in a vegetable garden; I've never seen it in the wild. Another is a group of plants related to blackberry ... but those always have prickles along the stem, while poison ivy never has prickles.

4-Sometimes the three leaflets in one of poison ivy's compound leaves has a "thumb" or an extra lobe; sometimes the leaves have a reddish color; sometimes the leaves are wavy. But they never have sharp teeth along the edges.

5-And the last and most definite characteristic is the arrangement of the leaflets within one compound leaf. Go back to your close-up photo of a leaf. Notice that the two leaflets on either side have a very short "stem" at their base ... but the leaflet at the end has a longer "stem" at its base. REMEMBER THIS! This one characteristic is very unique to poison ivy. When you see a plant with three leaflets, and the middle one has a longer "stem" at its base, stay away! The old saying is "leaflets three, let it be!".

Hope you're not scratching too much ...
