Found climbing up a tree in an open field at REFS in Coldspring Kentucky. It was warm and sunny that day, but there was not too much light showing through the overhead foliage.
There were not other naturally growing english ivies near it. They are common to this area.
The vine was average for an english ivy bush: around 10 feet in length.
I could not find any reproductive parts, but the leaves were smaller. Most were 4 inches long.
3-5 lobed leaves with an alternate leaf arrangement.

Found in along a trail in a forest at REFS in Coldspring Kentucky. It was warm and sunny that day, but there was not too much light showing through the overhead foliage.
There was a large clump of mayflowers growing near each other. Most likely one plant growing a large system of offshoots. They are not common because they are spread by native turtles.
This was smaller for a mayflower patch: around 15 feet long by 15 feet wide.
I could not find any reproductive parts, but the leaves were large. Most were 10 inches long and the plants were 6 inches tall. This is most likely to soak up as much sunlight as possible.
Palmately compound leaf arrangement.
