I have noticed there are no threads with (or maybe I missed them) links on where to buy MG seeds?
Is this a secret???? I did some research of my own and have bought from sellers on the net including ebay. I have no problem sharing the link but can not back all these sellers as I have not grown the seeds as of yet.
I've purchased some JMG seeds from many of those sellers listed above. And I've been happy with what I got.
I have also done an enormous amounting of trading over the past few years and received some really awesome MG seeds/vines in trades. I think the rarest cultivars/crosses that I have gotten came from trades, not purchases. :-)
I do a seed swap near the end of the year and that's one opportunity to get some more MG seeds that you may not have grown before. The folks here on this forum are mighty generous gardeners!
And don't hesitate to try cross-pollinating cultivars by hand. You can create some really awesome crosses that way! Some of the most unusual blooms I've gotten have been from crosses ... either my own or other's creations. :-)
