Those plants look great, my man! Bwiti is most certainly pleased!!! Basse’!!!!!
The more I grow this family of plants, and add seeds from different countries within Central Africa I am astounded by the variety in morphology, hardiness, chemotype, and the likely advent of interspecies hybrids considered varieties of the same species. Julian Palmer has used this to his advantage, correctly so in my opinion, by marketing ethanolic extracts of the round fruit variety as Tabernanthe manii (conveniently unscheduled, BTW). This may not be a legal ploy, as iboga is known to hybridize across species.
Furthermore, there are significant variances in alkaloidal composition across populations. The lesson here is grow as many seeds, from as many types of fruit, from as many forms and populations of Iboga as possible. I myself have begun the process of harvesting up to 25% of the side roots from plants I have that are around 10 years old or older. scrape root bark fresh, and get analytical data from methods as simple as iodine or Ehrlich’s reagent, to Thin Layer Chromatography (easy, but VERY useful), and beyond. Less than 25% lateral root harvest & the plant bounces back just fine. May not flower & fruit that year as it recovers, but next year it cranks along just fine.
The idea is this, from my perspective. Grow a massive amount of seed grown, biodiverse specimen, Test root bark alkaloid production in methodical ways, select. then it is time to move to aero production, and or liquid culture.
In the meantime, plant the ever loving deluge out of these plants. Flowering, fruiting, viable seed set; these all vary from plant to plant, and in diferrent conditions. Grow lots of seeds & select for what you want.
And don’t get me started on the phytochemistry of this group. Oooh La La! It is a chemist’s wet dream.
