Mine do best when I hand pollinate. If you can share pollin between two plants, not cuttings of each other it works even better but is not required to get seed.
Seeds are large and pear shaped.
Keep seed bed very moist untill germination begins. Reduce tempratures gradualy to about 60 deg. F. for the winter. I've had adult plants survive unnoticed failures in the drip irrigation system unharmed. Get the Internet just the way you want it.
