Looking for Coccinia Grandis seeds - American Source

Want to grow these as an annual in zone 7. There are European sources, but reports are the seeds are confiscated. Really want to grow these for herbal use. Also interested in anyone else's experience.

These seeds are not common here in the US.

Itsy, ebay, and Amazon do have them, but the caveat is that not all sellers at those sites are plant wise. I have had good experiences with the few plants/seeds I have ordered from them, but I have also heard some horror stories from others. (Like, after the plants had grown, it was discovered that they were not what had been ordered.) Buyer beware.
