Thanks for posting this; I've long kept a line of succession of Coleus plants after noticing the rumours of possible phytochemical content. This was bolstered by a possibly coincidental lucid dreaming experience after eating a single leaf, which also coincidentally fell off the plant when I woke up in the middle of the night.
 Anecdotally, one plant that could realistically fit the description 'Electric Lime' showed the most promise in this direction when compared to more purple-tinged varieties on an ad hoc, in vivo basis.

I'd be interested to know the exact distinction between 'Electric Lime' and 'River Walk'. It's likely time to be taking a look in my local garden centres (EU).

I wonder if there are other cultivars, or wild non-cultivated plants, which have higher concentrations than the 'Electric Lime' cultivar that was used in this study. If so it's probably still very low amounts, still interesting all the same to see Salvinorin pop up in this species! Growing conditions also seem to influence concentrations.

Ahh yes, Salvia recognita has some lovely flowers too! Really nice to grow, although a bit of a slow and small growing plant compared to some other Salvias. Salvia glutinosa is another interesting species (less so than S. recognita) which grows very fast and large which could make it more attractive. Hawk Moths seem to love S. glutinosa, it's the only plant I've noticed them on in the garden.
Another post on STS on these Salvias: New psychoactive Salvia species with Salvinorin A & B discovered!

For any UK members reading this and wanting to grow Coleus 'Electric Lime' - in early spring for many years now Tesco’s across the UK has sold multi-packs of different Coleus cultivars with one of them being 'Electric Lime'. It can also be found in garden centres in early spring too so keep an eye out over the next month or so. Usually they're only around for a short period. Sometimes on eBay too.
Also, just as a heads up in case you find any which are unlabelled and look like it - there's another cultivar which looks very similar called 'River Walk'. Still a beautiful plant but if you want the 'Electric Lime' cultivar specifically be sure to find a labelled one or be very familiar with the differences of these cultivars.

Very cool since there were some random reports of it being active. However you would need to have 40x minimum to have any psychoactive effects.

Salvia recognita seems most interesting however the availability of coleus is very high and the colors are wild.

Title
The influence of cultivation conditions on the formation of psychoactive salvinorin A, salvinorin B, rosmarinic acid and caffeic acid in Coleus scutellarioides

Abstract
Coleus scutellarioides (L.) Benh. is a popular species in the world, known for its characteristic magnificent colourful leaves. The study has revealed that the contents of rosmarinic acid and caffeic acid are significantly higher in the plant tissues cultivated in vivo than when under in vitro conditions. The performed qualitative and quantitative analyses confirmed the presence (whose averaged content) of salvinorin A (6.65 µg/1 g of fresh plant) and salvinorin B (50.46 µg/1 g of fresh plant) in tissues of Coleus scutellarioides (L.) Benh. of ‘Electric lime’ variety. The greatest quantities of these compounds were recorded for plants cultivated in vitro on the MS medium enriched with NAA (naphthyl-1-acetic acid) at a concentration of 0.5 mg∙ dm–3. The research detected differences in the amounts of compounds between plants grown in vivo and those cultivated in vitro. Addition of plant growth regulators into the breeding medium under in vitro conditions was found affecting the amounts of compounds in plant tissues.

I managed killing one once when 'helping' it out of the husk. Wait a good period of time and only attempt doing so once you're certain it wont happen naturally. The plant being more mature at this stage will also make it more robust. I found making sure the husk remains moist and pliable increases the seedlings chances to shed the husk by itself and also makes it easier for you if you do go down that road. Sphagnum was my solution and did the trick.

Are you ready to plant the seeds or do you have a reason to store them awhile? It is my understanding that iboga seeds can be dried lightly(meaning not let to sit out in the open air to continue to dry for an extended period) around 2-3 days and will store maybe a few months before loss of viability entirely. It's not a species you ideally want to store the seeds. Max viability is while fresh. Being a tropical species the seeds are meant to attempt to sprout as soon as possible in its natural environment. I believe the seeds will begin to sprout inside the fruit(if it rots and doesn't otherwise dessicate) eventually. I could be inaccurate in some of those assessments but it's what I think I've read in the distant past.

It's not super hard to get growing. Sometimes you might have to help them shed their seed coat. Be very careful with a razor blade and lightly cut it free. I've done it all in one shot. Once you figure out the orientation of the insides it'll be easier. However I've sprouted ones that shed the coating themselves no problem at all. It's possible dried seeds are more likely to have a hard time with dropping the seed coats. Start them in bight shade. Like the edge of where the light hits in a shaded area without too much direct sun. Keep inside a humidity dome while sprouting. A clear plastic box works great. Don't over saturate the seedlings. Then just grow them on out. Dappled light seems to be their preference but I've also grown in full sun. Most all my experience is outdoors but adjust logically for an indoor setup knowing some of these general factors.

Drying and drying seeds: After being harvested, seeds need to be dried and dried for best preservation. When drying seeds, you should not dry them directly on a concrete yard or brick yard. You should use a squeegee to dry the seeds so that they dry evenly and are not deformed by temperature.
 If drying seeds, it is necessary to maintain a temperature of 35 - 40 degrees Celsius. Good seeds are round, plump, uniform, and have a high germination rate.

After drying the seeds, you need to let the seeds cool completely before putting them in storage tools. Cooling the seeds prevents the seeds from respiration and water vapor loss during storage.

Sorry that this isn't aligned with your plan and question but IMO the best way to store seeds is to sow seeds. Some plants simply don't have any mechanism emabling their seed to remain dormamt and viable because they don't need to. We view this behaviour as the norm but maybe its better regarded a special trick some plants have come up with due to environmental pressures.

Modern, try an approach graft instead. It's a different style which is more suited to tropicals that don't go dormant.


A quick googlization will get you all the tek info you need,

I'll try this on my third attempt. My first attempt which is what I posted here failed. I think it's due to not allowing the graft to remain under wraps for long enough. I did a second attempt the start of Feb and I'll be leaving it wrapped for atleast a month rather than 2 weeks. May even leave it longer depending on how it looks. Under the baggy the psychotria did remain alive but the graft union was not strong. There did seem there was some union but it failed.

I have more psychotria growing and my 'kratom' are specifically grown for this experiment so it is fine.
