..here is a recommended list of the TOP 8 ACACIAS TO GROW orientated for Nexians..
all except confusa & simplex [Pacific Ocean] are originally australian native, therefore will in most cases tolerate temperatures down to minus10°C (to minus12°C in one German report)
A. floribunda is already known to be naturalised in southern parts of Europe..other species are grown in Germany and the UK successfully..the isotype of the species was named Mimosa floribunda in France nearly 200 years ago!
A. confusa is particularly suited to tropical climates, Hawaii etc..
and A. simplex is the highest % of alkaloids reported in an acacia [3.6%]
A. acuminata (Narrow leaf & small seed var. ) have the highest just dmt% known from phyllodes [up to (> )1.2%] ..while not on the list, A. burkittii is now considered a sub-species of acuminata, and also has very high content, and drought resistance..will tolerate down to at least minus 8°C, likely minus 10..
and A. phlebophylla, apart from being a great and powerful plant, is good to grow for conservation reasons (it's very rare) ..will tolerate snow for some weeks..
..seed of all these species* are easily commercially available from many sources..google search the Nexus for germination and growing parameters..
[*=exception A.maidenii x obtusifolia..is being slowly introduced to horticulture..however garden encouraged new hybrids could fairly easily be created.]
re the % rating scale: (+) would indicate only a very small % of alkaloids..(++) here is somewhere in the 0.2 - 0.4% range..(+++) around 0.5 - 0.9% and (++++) ..1.0% and higher..an > indicates either "up to" or 'seasonal variation' etc
ALL are fantastic friends who will get to know you, and you will grow to love..

_________________________________________________________________________________________
SPECIES ________%RATING____ADVANTAGES______DISADVANTAGES
A. acuminata var.___>(++++)_____'Cleanest', Leaf good__slower grower
A. confusa [S.E.Asia] >(++++)____Well known usage___suits warmer climates
A. floribunda____(++) > (+++)____Fastest Growing_____sometimes 'Milder' extracts
A. maidenii Xobtusifolia(+++)_____Fast; good profile____has some other alkaloids
A. neurophylla_____ > (++++)_____Drought Tolerant____phyllodes have ß-carbolines
A. phlebophylla_______(+++)_____Alpine climate,clean__ harder some climates
A. simplex(simplicifolia)(++++)____High%,Salt Tolerant__some NMT (1 formal test)
A. victoriae_________(?) > (+++)____Seed Food.,low water__may be variable &/or5meo(?)

Note: in ideal situations/conditions some species can reach 6-7 ft tall in 3-4 years from seed…they can usually be pruned or 'tipped' to encourage more bush or branch..
of the other 88 or so species around the world known or with some evidence of CNS active alkaloids, there is much for the grader or horticulturalist to enjoy just in growing these plants..and many are good nitrogen-fixers, improving impoverished land..
Pioneer Species…! this is why i like them so much..they are helpful..![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
