Both lots of flowers are white. Boy flowers have a mass of little stalks coming from the middle with anthers on the tips. Similar to (but much smaller than) those on lilies. Girl flowers have a ring of anthers and a central set of semi-translucent 'threads', and a swelling behind the flower.

Expect the vine to wander for 4m+ and wrap around anything. It has similar habits to Wisteria.

The flowers aren't that popular with bees, unfortunately. Bees are the pollinators and it needs a fairly high density of beehives to get a crop set (not to mention good weather).

I'd expect any fruit to be much fuzzier and smaller than the ones from the supermarket, although they may come true to type. Not sure about this aspect.

I bought one kiwi and cut away as much of the non-seed containing fruit as I could. Then I put the remainder of the fruit in a bowl of cool water and smushed up the fruit with my fingers. "Naked" seeds sank to the bottom and the pulp floats to the top. I would remove the seed-free pulp bits or let the seeds settle and decant off the pulp. Then repeat with clean water. After a few go-throughs I just had seeds and lost very few to the decanting.

I put the seeds in regular potting soil in a plastic chinese food container with a translucent lid, and put it on a sunny window ledge. Within a week, I had a carpet of seedlings.

This was my mistake. I wasn't familiar with how the plants grew and I tried to separate them all by hand and repot them. In doing so I lost nearly all of them. BUT - a couple of them made it, and have been planted outside in my garden. They grew about 6 feet in the first year up the side of a fence.

Next time, I'll use those peat pellets.

Good luck.
