Do you know this vine?
First-timer on this forum--I normally hang out at the winter sowing forum.
A friend gave me a hunk of what she called a white-flowered trumpet vine. But I'm not sure that's really what it is, and The Google hasn't been much help.
The vine has a massive woody root, and the leaves and stem are covered with fine fuzz. The piece I got was dug up on a hot day in zone 6b Maryland, so the leaves are pretty ragged. I am told the vine needs full sun.
Can anyone tell me what this plant is?
