Can anyone recommend a fast growing

Best find your local plant nursery and ask them. I would also ask how best to prepare the land and what care they will need.

We are at 450 meters with cold, wet winters, maintain a small vineyard of wine grapes, and use Fragola Americana for screening and visual privacy. They grow quickly, have large leaves, and seem to be more disease resistant than other types.Fred

Good advice, Fred. I would only add that Fragola grapes are delicious and very healthy. Lots of antioxidants. Highly recommended by nutritionists.
