I've had this growing in my garden since I bought the house. It's extremely vigorous and is overgrowing a number of things including one of my veggie beds. I have though a lot about ripping it all out but thought I should get an ID first and make sure I want it all gone.
I have googled a few things and think it may be passiflora caerulea, (but am absolutely unfamiliar with these plants except for eating the odd passion-fruit bought from the shops). I have only seen a small orange fruit on this plant once, last year. Lots of flowers, bugger all fruit on this plant for me.
And if it is passiflora caerulea, can anyone suggest any possible things people use this plant for other than aesthetic appeal?
