ID request on self-seeded tree

[zed240]

These have self seeded in my front garden. There's actually a few of them. I've been intending to rip them out for a few months but they grow pretty fast and I've procrastinated on it.

Would love to know what they are if possible. I thought maybe some kind of acacia but that's just a guess with no substance. ;)

[EDIT] - I'm in Adelaide's southern suburbs

Looks like a fern of some sorts? Def not an acacia (that I've seen anyways)

Thanks! Now I wish I did rip them out earlier! I'll get to it in the next few days for sure.

I've never noticed flowers on mine but it looks like the buds are well on their way. I hope I've caught them soon enough that they haven't seeded yet.

Steady on! Yes it is a weed and can become a problem, but it is not generally hard to eradicate from a localized area. It is not a significant bushland weed in south australia it grows opportunistically but the seeds are not generally transported very far.

I have planted these in my sa garden to grow as a very quick shade and windbreak for more sensitive plants, cause they can grow 6ft in a year no worries even without much (any) water or ferts. My conditions are very harsh and they very rarely self-seed in my environment. Being a legume they will also fix nitrogen in your soil.

Point is, if you need a fast growing tree for shade or wind protection in your yard that you have no qualms dispatching in a few years, then nature has provided you one.

But if you don't, by all means eradicate it now.

These can grow up to 4m and occasionally live to 10-15yrs.

Thanks for the info Micromegas.

There is about 5 that have started to grow all within about 2 feet of each other. They aren't really in a place I would want them to stay. I might see if I can remove them and re-pot them or something in case someone else I know ends up wanting them. I can't picture where they would come in handy for me in my garden...

So if anyone in Adelaide wants one, (or more) of these and will pick them up send me a message.
