Climber choice

Our kitchen widow looks out onto next door's wall.  They are no longer gardeners, so to improve the view I plant, with their permission, some marigolds in the very small dry border underneath the wall.  Their ivy was getting out of control so we chopped its stems and it is now dying off.  We will in time remove the ivy from the wall, and dig out the roots hopefully leaving the existing trelllis.  Next door blithely says they would like a climber up the trellis, but it is I that will have to source, water and maintain this climber    so I want pretty or pleasant to look at, low maintenance and able to survive dry conditions.  W

I'm asking for plant suggestions.  Paul would like something good to look at while he washes up.  I have thought variegated ivy which is less thuggish than wild ivy ( plus I can take cuttings of some I already have), clematis but their flowering period is relatively short and can look tatty.  Not virginia creeper it is messy ( I think) .  If annual, it will be me that has to propagate it so easy ones please.
