What kind of tree produces these seed pods looking like spiky balls?
I recently moved to southern Virginia near the coast (about 15 miles in from it). All over the ground are these spiky balls that I assume contain seeds to the tree they fall off of.
There are literally thousands of these things on the ground. When they first fell, they were green in color. I would have grabbed a picture of the bark of the tree, but the tree that dropped these is covered in some sort of ivy vine that's growing up it and I couldn't get a good picture of the bark. The trees aren't near any water sources.
