Hello Benjamin,
Sorry for the delay, I am currently on a
project in Ecuador where the internet comes and goes with the rainstorms and landslides. For a living annual snow fence I think Michael and Jay hit the nail on the head, Jerusalem Artichokes, Sunflowers, and Corn would be the first plants that I would try. Each have a tall sturdy stem, the sunflowers and artichokes
should hold up the best, as they are deep rooted and very strong plants.
