passion flower plant, blue/purple flowers (Highbury Barn N5)

passion flower plant, blue/purple flowers, grubbed up with loose earth on the roots, vine about 1m long
NB a real thug that will grow over other plants (and possibly pets) if you let it. Suggest best grown in a large container - with a tray or saucer underneath, or their roots will grow out through the drainage holes and infest a large area (it’s grown under my patio which is nearly 3m wide and come up the other side).
