Eon, you crack me up! Deep purple thumbs!
So, I'm going to count on you for the reports on grafting and how vigorously the roots grow. Keep us posted! Don't let this good idea evaporate. You have the time and inclination? I think in the future, the supply of this precious root will have to be very carefully addressed. The number of plants alive and growing in the world today is finite. I have thought a lot on the sustainability issues surrounding the use.
Friend Ed, the seeds I have are Iboga, they're about raisin size and wrinkly, the color of cinnamon.
Of course, I have them in MX!

I'm keeping them warm and moist, per a friend's recommendation, with warm being the important point. My dear husband MacGyvered a timer light that comes on to see them through the night. I'm pretty sure one has germinated! It's hard not to poke and peek, lol.
As far as Iboga rootlets being tasty, GAH! Bitter, bitter, BIG bitter taste. We're not talking salad green bitter, but mega mouth takeover bitter. Ain't no Roquefort gonna disguise that! I'll take mine neat, thanks, and enjoy knowing the tatse fades, lol.
Love to all y'all.
