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.
