Gordon I grew this a couple of years ago & if memory serves I only had one vine & I got fruit because there were male & female flowers on the same vine. Trichosanthes can twist & turn or in some countries they actually tie rocks on them to keep them straight when hanging. Mine were from Baker Creek & were supposed to be an extra long variety, but my only fruit was less than a foot, however, that summer was exceptionally brutal, my gourds literally cooked on the fence, so I assume it would have gotten bigger & I would have gotten more than one fruit if conditions had been better.
