Game of thorns
MOST vineyards, particularly those that want to attract visitors, plant roses at the ends of the rows of vines. The general story is that they act as an early warning system for spotting mildew but the Austrian growers had a different story to tell. Apparently a thorny rose bush encouraged a horse pulling a plough to take a wide berth around the end post in a vineyard and so it wasn’t knocked down. Of course, now the roses just make the vineyards look pretty.
