first off, i am quite new to this site. every now and then i will take a peak and skim through different forums for what peaks my interest, but today is the day i just had to join the forums.
i am in love with most psychedelics i have done and my most favorite now has been DMT, doing research i have found many plant life in my area which contain this wonderful chemical, living in alabama i was overwhelmed when i had found my first wild passion flower vine and an abundance of mimosa trees. now that i am back in florida i noticed what appears to be a mimosa but cannot quite tell as it is still quite young. the mimosa i have found in alabama had its flowers and were quite large. in the images i have i tried to get the best pictures i could of the stems, the main trunk itself and the front and back of leaves. could anyone help me identify if this is one of its sub-species and if so which species? much thanks

Hello there, what people in Alabama call Mimosa or furmosa is actually Albizia julibrissin.
I've grown several of those & judging by the stem & leaves, I believe that is what is pictured.

My understanding is that true Mimosa trees don't naturally grow within the continental United States; though you could get some seeds & try growing them.

thank you so much for that, i will just let the plant be and take its course in nature.

i know alot of phalaris grows around my area so i think i will focus on that instead of the trees until they are fully grown

They're not mimosa hostilis but they're true mimosas:

Mimosas in the USA (&Puerto Rico)

Pretty surprised to see M. arenosa listed as growing in Puerto Rico.
