Hi Nullzero, did you find Momordica dioica seeds? Are you still looking?
I came across this post while researching for info on Momordica dioica.
This is my Dad's favorite vegetable. I sent some seeds back home and so far my Dad has 6 vines that are finally producing; however, they keep dropping while still young. He believes he has 3 female vines and one male. Two vines, he's not sure on. Anyway, we're still trying to figure it out.
I just sourced some fresh seeds to send back home, and if you're still interested, I'd be happy to share some. Just PM me and let me know.
If anyone else would like some, just leave me a PM. Thanks.
