Why on earth would anyone plant.....

Arum italicum pictum. It spreads by little brown bulbils which are nearly invisible. And Vinca!

I've got an established clump of bamboo that also screens us / neighbour. Clump-forming are OK I think (at least it hasn't offered to spread in 20 years).
I also have the creeping kind, but that's in raised bed. It's deciduous so I grow spring bulbs v successfully in the beds as well, & verbenna bonariensis & salvias.

Bamboo is fine so long as you dig a trench to contain it. Next door’s open garage that he added two garden sheds to and stored loads of junk in full view stands 6ft above our land and looked hideous. What to shield it with? Bamboo what else - it grows to 12ft so hides shed and it is not covered by the high hedges act. An added bonus is using the canes in the garden for myself and friends.

Add Japanese anenomes. The previous owner of our house did and then let the garden run wild, The roots grew up between the cement plinth along one side of our house and the brick house wall forcing a gap at the top so that when it rained the water ran between plinth and wall causing a damp problem indoors. It is costing an awful lot of money to remedy the situation.

Someone at an end house nearby must have planted the Russian Vine which trailed over their fence and has now overtaken the hedge grow and is smothering everything else.
