Mum has 2 in her garden. They rampage along her fence at quite a rate of knots in the summer. She has, supposidly, a male and female plant, and gets masses and masses of flowers in late spring, but not a fruit yet! Shame. I grew a load from seed last year, just to see if I could, and I did! Thus, I am no help what-so-ever, other than to say, do you have a boy and girl plant and plenty of lllloooonnnnggggg trellis to support them?
