One more question. We have a lovely view of the nearby mountains from our back patio, except there is a construction company that parks their unattractive vehicles a few hundred yards away.

We need something that will grow 10-15 feet high along a stretch of about 50 feet of fence. That way we won't have to look at the road graders, but we can still see the mountains. The fence isn't particularly sturdy, but it does keep the neighbor's horses from getting into the yard.

Thanks for any suggestions.
