Fast growing plant

[LittleEsme]

I have a really unsightly wall that I'd like to cover. It's a boundary wall in my garden, made with concrete blocks and rendered over. It's meeting a lovely old pennant stone wall. I'd love for some greenery to cover it (and quickly) but the wall meets concrete so I can't plant anything in the ground.

Does anyone have any suggestions please!

Bamboo in pots? I wouldn't normally suggest bamboo because its invasive but if you can only have something in pots then it might be good?

If it has to be in a pot how about a clematis? How much room do you have in front? Could you put a really really big pot with a small tree/large shrub in it? How tall is the wall?

The wall is over 12 foot high x 15 ft wide and the space between that wall and the side of our house is about 170cm so not a big gap.

Passion flower in a pot. I was flabbergasted by how quickly mine grew.

Tricky. How much of that 1m70 do you actually need? Could you put a 60cmx60cmx60cm sized pot there or would it impede access?

I second passionflower. Once established it grows fast!
Some clematis grows fast too - so many varieties.

Passionflower or Kiftsgate rose will both cover a large area of wall. Climbers need to be planted 60cm away from the wall and then trained up it, so maybe you could plant one in the ground? Both too vigorous for a pot probably.

There is a higher bank nearby (about 20ft away) and I suppose in time that it could be trained across?!

I'm clueless, I should add.

I could run a line of pots at the foot of the wall?! Or would that look naff??

How can I encourage something like ivy to grow downwards, then upwards?! Is it possible??! There's ice somewhere along that shared wall - could I start encouraging it across??!
