Up to you really - the passiflora will probably smother the Fuchsia by end of September, but maybe you don't mind that.

I would definitely keep my pruners handy!

I've never heard of a climbing fuchsia - more details anybody?

It is called Lady Boothby, quite new but most GCs seem to be stocking them.
They grow to 5 or 6ft high but are not a true climber and have to be supported.
They are also hardy.

They've been around for years, or at least, Lady Boothby has, it was a remarketing exercise sometime in the last 5 years -rebranded 'climbing fuchsia'. Frankly, it climbs about as much as I do - i.e., not at all, lol! Has an upright growth habit though, but, as someone else has said, needs support.

So another good idea bites the dust...
