This is kudzu, covering up everything. It was imported from Japan in the early 20th century to prevent soil erosion in the American South. If left alone, it will cover anything in its path: trees, power lines, houses, vehicles. It's nutritious forage for cattle, but if the cow lingers too long over its dinner it may find itself covered by kudzu. I read somewhere that the vine grows about one foot per day. No wonder they call it "the vine that ate the South."
I'm sure some Southern mystery writer has hidden at least one body in a patch of kudzu. It seems like such a perfect place.
