So I found a vendor offering these seeds, sold as "jurema Branca"..which sounds off as I thought it was established by now that that is mimosa verucosa..

this is what the vendor description says..

"Native to the cool subtropical Parana' plains of Southeastern Brazil, and closely
related to Mimosa tenuiflora / hostilis. Thrives in many kinds of well-drained soil
and exhibits remarkable erosion control qualities. Young seedlings should be kept
in a semi-shaded location until they are well established. Found to be extremely
cold-hardy, reportedly surviving outdoors even in northern parts of England.

Highly valued in folk-medicine and traditionally employed very much like Mimosa
tenuiflora. Phytochemical studies on the leaves and roots have found great
similarity among the two species and would seem to substantiate the virtually
identical usage profiles."

The wikipedia articles on it claims that it contains bother DMT and NMT..can anyone confirm this? has it been used? Do we know if the % is decent? It is apparently more cold hardy than Mimosa Hostilis so it would be something I would like to grow as my hostilis is all doing well here so this tree should do even better.

That interests me a lot. I didn't think there were really any viable candidates for outdoor growth in the UK.

Well then also look into desmanthus leptolobus and acacia obtusifolia.. Obtusifolia is cold hardy, can withstand frost and some snow and is potent enough in the leaves for extraction so you dont have to rip up the roots.

Also phalaris brachystachys and AQ1 for the warmer months.

Thanks man. Looks like I have some research to do

..the % DMT/NMT found in M. scabrella by de Moraes et al 1990 was small (0.035%) however this is only a single test, and many such phytochemical tests do not attempt to maximize yields (e.g. the plant material is extracted for 10 minutes in cold solvent)
..it is recorded growing in Newcastle-upon-Tyne..
other acacias which will tolerate southern UK outdoor conditions are Acacia floribunda (up to 0.5% mainly DMT in leaves, more in bark) and A. baileyana (reports of tryptamines and betacarbolines) which is known to be growing in England..

I have a number of various acacia seeds on their way..obtusifolia is one, and I think can handle the winters where I am as the coldest it got this winter was like -7 one day..and that was only at night. Normal temps here are above freezing all winter long..floribunda I have comming as well but was unsure of trying that one outdoors here..I wa going to keep it in pots like I am doing with my hostilis trees right now and just leave them outside for about 8 months of the year..but I dunno if they would like being moved like that..

Got some brachy seeds comming too..also acacia simplex, confusa and acuminata...and also some weird stain of "muricata" that noone seems to know what it really is when grown..

Thanks for the info. Very interesting. I'm looking for something viable to grow on the homestead.

Nice

..floribunda occurs naturally in slightly colder conditions than obtusifolia (i.e further south) ..floribunda was being grown in France in the 1800s..
both should be able to take down to minus 10 degrees C before frost damage occurs..though growth should be dormant below minus 1 or 2..

wow thanks nen!

I will germinate a few of both the obtusifolia and floribunda and put half of each in the ground once they are big and strong enough and see how they do compared to the ones I dont put into the ground. I have wanted to try growing obtusifolia for a few years oudoors here so this will be fun.

..groovy jamie ,
floribunda is recorded in the wild in locations which have reached minus 11 degrees C..
for sheer amount of dmt in the branch bark the most consistent aussie has been A. acuminata which is recorded wild in locations with records of minus 7.5 degrees C..
acacias don't mind being moved in pots, they just hate ground transplanting once established..always like some sun..

^ The acuminata content as the most consistant is not including phlebophyla though right? Am I right that acacia phlebophyla is the highest yielding acacia out there for leaf or branch content and for the purity of the alkaloid profile? Of course phlebophyla is endangered on the mountain where it grows wild so even seed collecting there(let alone harvesting for DMT) is unethical..and most attempts to cultivate it are a failure..

That is one plant I would love to grow though..I can dream..

So I guess acuminata I can try outdoors here year round...nice!

..while the acuminata leaf sample tested by endlessness had more ß-carbolines than DMT, most people have been getting up to 1.5% (average 1.2%) mainly DMT from the leaves (up to 2% bark in some cases) ..no other acacia known has this high a total alkaloid content in the leaf..the ß-carbolines thing was probably due to the sample being the broad leaf variety (rather than narrow) , or else seasonal..that said, the leaves with the ß-carbolines are orally active on their own..
..also it's a lot easier to grow than phlebophylla..
floribunda has more DMT in the leaves (phyllodes) usually than phlebophylla..

to germinate, i usually place acacia seeds in water, bring to boil over about 7 minutes, then let soak overnight until swollen..

^ wow that is very high. I read that these 2 species were good for high alkaloids in the phyllodes but I did not know it was that high..I got the narrow branch variety of acuminata so that sounds good..

Ive been spending hours lately lurking alot at the corroboree and I must say I am impressed. Australia has their s$#t together it looks like, aside from some people harvesting unethically and overharvesting etc..I guess with local laws making it hard to get other plants shipped you just make due..oz seems to definatily be making due!

I would love to see others more people here in NA growing mimosa and trying to grow other plants like the acacia's and the grasses etc..I think people are just getting this now as the reality that someday we might face the same legal restrictions as people in australia sets in. Better get on this now. We will all be that much stronger in the end becasue of it..even if people just start with a hostilis house plant..this tree is a tough plant and even if you dont want to dedicate space to growing it large or having multiple trees just having even one smaller house tree keeps it around to be shared with others that come along who do have the space. Spread the plants around to the community!
