I finally figured out germination of acacia seeds..I got a few straings going now but I wanted to start this thread for confusa for a number of reasons. Confusa seems to be a fast growing acacia with good alkaloids profile throughout the tree, likely the phyllodes as well. It is faster than any of the other acacias I have going. It put out some phyllodes already just in 2 weeks. It seems hardy and easy to germinate. It might be a good tree for people in northern climates to explore for indoor cultivation and greenhouse cultivation etc..

Mine are going in an indoor greenhouse right now with grow lights and a fan and I keep it warm and humid in there..this is how I germinate everything. I will be moving them out of the greenhouse into a sunny window when they are more established..I want to start a lot of these guys if they will take to my large living room window that way..just harvesting phyllodes eventually would be ideal.

If anyone else is growing this tree please post anything you have learned about it's cultivation here and pictures if possible.

Woah way to go jamie! They look beautiful and strong What soil mix are you using and what is your exact process for germination? I received my Acacia seeds yesterday (A.karroo, A.nilotica, A.sieberianna var woodii, and A.albida) and should be able to get them going in the next week. Keep up the great work!

okay the soil I am using is a tropical soil, that I mixed in about 1/1 mix with perlite for airflow.

I had problems last spring with germinating acacia seeds in a plastic humidity container thing. They would germinate and then rot. I was also doing them in peat pellets though.

I decided to try it in my greenhouse this time where my caapi seedlings were already doing well. It is about 5 foot tall indoor greenhouse with 4 sections/racks..I put 2 lights in there and 1 fan. The fan makes a big difference becasue it keep the airflow going to avoid mold and rot etc..

I nicked the seeds and soaked them in some hot water for about 24 hours..they should swell. Once they swell it means they are starting to germinate. I think plant them in little seedling containers with the soil/perlite mix and mist them a couple times a day in the greenhouse to make sure it stays wet so they dont dry out. I had sucess now with acuminata, obtusifolia, floribunda and the confusa with this method..I am still waiting on the simplicifolia to germinate but I only had 3 seeds and 1 of them never swelled at all..the other 4 species have all germinated and are putting out bipinate leaf..the confusa is the only one that had already put out phyllodes. I think the others all take much longer to get to that point, as they are australian acacias so seem to be more similar to each other compared to the confusa, which is from tropical asia.

It seems like a faster acacia anyway so I have hope for the leaf content..there is much interest in psychotria alba at the moment as a viable indoor DMT plant, and confusa also seems like a good choice..if it keeps up this growth rate.

wooot go jamie leading the way for the nexians on the growing front! keep it up I'd agree that its highly likely that the phyllodes contain alkaloids too.. seems to be the case with all other acacia... would be interesting to to find out the ratio of nmt to dmt in the phyllodes in comparison with the bark.

They really do look healthy and budding jamie! Congratulations. I have not grown confusa but I want to now.
I've had to watch out for small native rodents eating little ones that size. And cows eating the tops of bigger seedlings! They must feel safe and loved indoors with you jamie. Thanks for this thread!

cute & healthy looking seedlings. if hawaii is anything to go by, they grow well at 200-800ft above sea level, with lots of water and excellent drainage to prevent root rot.

Jamie, I recently acquired some confusa seeds and just began to soak them in warm water. Do i need to soak them for a full 12 hours, or should i wait until they swell? Will taking them out of water before 12 hours, or before the swell, kill the seeds?
Also, is Acacia Confusa salt tolerant? I live in a very salty environment and this could mean the difference between life and death for my plants.
Those plants look great! How are they currently faring?

Hey Godsmacker,
Did you pierce the outer part of the seed shell first? (With knife or sandpaper)
It may be quicker to soak in boiling water as well.

It's pretty hard to kill seeds...
Soak them in near boiling water until they noticeably swell and either stick them into the ground at seed depth (so you can monitor their germination) or put them in a plastic sandwich bag with a moist paper towel and keep in a warm location.

If some of the seeds don't swell, just repeat the process with hot water until they do.
Acacia's are very easy to germinate IME.
