What to plant to scramble all over a big black plastic tank?

[linspins]

Hello! The people in our house before us were water-butt crazy, and installed a HUGE round plastic tank to keep spare rain water in. It's mostly set into the ground but about a metre and a half above ground. All jolly useful in this rain-parched climate, but the thing is an eye-sore. Does anyone have a good idea of anything I could plant that would scramble up/over it and disguise the thing? I could wrap netting or something for stuff to cling on to? Anything evergreen?

Could you put a couple of clematis - evergreen and non-evergreen for interest? Cl Armandii is evergreen and very vigorous - flowers early spring. You could mix with one of the more rampant montanas. Otherwise there is the 'lovely' fallopia which would grow fast but quickly takes over. There are honeysuckles which are evergreen too e.g. Halliana.

Is there any way of screening it off with fencing or willow etc?

I could sort of screen it, and may well do so with a small hedge, but it's visible sideways because it's right next to the garden path too. Clematis a possibility then!

Clematis will only provide cover when in leaf and flower, about 5 months of the year. A nice variegated ivy will be evergreen and grow quickly. Another advantage is that it is hardy and you can prune it at will. If you go for ivy, don't pay for it! Go to the woods and take some. No need to dig it up, break segments off the tree, the little bumps along the stems will root in no time. Take the leaves off leaving a few at the top and stick the stem into the soil. Then neglect. Job done

Russian Vine, otherwise known as 'Mile a minute', will cover it in no time and you can give it a good hack back whenever it gets too big.

i have just bought some russian vine to cover our horrid oil tank! but wondering how to anchor it to the tank? don't want to pierce holes in it... any ideas??

Parthenocissus tricuspidata (Boston Ivy) is massively vigourous, and self clinging - has little suckers that adhere to a surfaces so no need for support. Will lose its leaves in Winter though.

Russian Vine will need some support - netting might be a good option.

Musaki, I was going to cover our tank in plastic mesh or netting, either green or black, for climbers to scramble over.
Good ideas with the ivy. Might go for that with a small evergreen clematis for luck!! Thanks all.
