Passion Flower; Passiflora:
Admittedly this is a very pretty plant, but it grows fast and gets big – over 30ft. So not for a small trellis or a little arch. It needs strong support or it will break the trellis.
It needs frequent cutting (your main chopping is spring) and it self clings with lots of little tendrils, which is helpful, unless they wrap around the gutter!
Anyway, you know what you are letting yourself in for if you buy one.
