This idea is great if you're needing to fill up space:
"Buy extra vines of airy texture and short to medium stature (like 6 to 10 feet tall, not the 30-footers), and train them up some shrubs. Small-flowered clematis are great for this, like the one just starting to open (above) in my Corylopsis or winter-hazel."
