Passiflora caerulea vines, still quite small, but can grow and climb fast! They're fine outside except in a very cold winter, but should be OK if planted in a sheltered spot e.g. near a wall. Pretty blue and white flowers and golden fruits (theoretically edible, but not worth the effort); they seed everywhere if not gathered up, which is why I now have lots to give away.
