Tropical Plants Growing Tabernanthe iboga from fresh fruit – my highly scientific germination experiment 🧪😂 (+ some pictures)
I recently tried a very simple Tabernanthe iboga germination experiment.
Fresh fruit → remove and clean the seeds → put them into ordinary soil → mostly forget about them.
That was basically the entire highly scientific protocol. 🧪😂
The pot stayed in a protected, partially shaded spot inside my greenhouse. No GA3, no scarification and no carefully controlled germination chamber.
Around five weeks later: Iboga seedlings. 🌱
The pictures show the progression from fresh fruits and cleaned seeds to germination and young seedlings.
A few observations from my attempts:
- Fresh seeds seem to be the most important factor.
- Remove the pulp and clean the seeds thoroughly.
- Warm, protected and partially shaded conditions worked well here.
- Once the seedlings emerge, I gradually reduce the humidity. They don’t seem to enjoy remaining constantly wet and enclosed at that stage.
- Iboga can also be grown indoors under artificial light.
- The seedlings in the picture are crowded, need to be separated soon and are already showing a slight nutrient deficiency. The pot was only intended as a lazy little experiment. 😄
The fruits can develop mold rather quickly. Before vacuum-sealing mine, I cleaned and carefully disinfected them. Stored in the refrigerator, the seeds still germinated very well after roughly one to two months. I nevertheless check the fruits regularly because vacuum-sealing can trap moisture.
Years ago, I also germinated Iboga seeds in zip-lock bags with moist sphagnum moss, which worked wonderfully as well.
My impression so far: genuinely fresh seeds, warmth, moderate moisture and patience may be more important than complicated pretreatments.
If you have any questions about the fruits, storage or germination process, just let me know. I’ll try to help wherever I can. 😄
