cup n saucer vine questions :)

[4390evans]

I've sowed some cup and saucer vine seeds, not sure as of yet where I am going to put them but they look lovely so Ill make some room somewhere

So I was wondering......

Is there any particular things they like or don't like?
Which area should I put them in?
Are they invasive?
Would they benefit being beside any type of veg?

Thanks guys
