HI, figrat has beaten me to it ! If you go with this one get stocked up with a good weedkiller !
Some clematis are quicker than others.
If you want to add triffid amongst it all , then go for ...... what I call the giant Thistle it will grow a couple of metres tall , problebly with a dollop of horse muck around its roots will grow gigantic even more . I wiil try to find the name for it . The plant itself grows with grey felty leaves and prickles looks good, you may need to stake discreetly , it will branch out from the main stem . Iy has big purple thistle flowers. at the momant all I can think of is the " scottish thistle " but I will check this out .
Another you might use are "Cardoons" similar though I think it was known as a veg in the victorian times . They ate the young leaves .
