Seems like you have the specie for the seed pods you found but I thought this might interest you. Shows some of the trees lining some of roads around Adelaide.

thanks blue, Yeah I've seen this snippet. was actually driving down crossroads and noticed the trees out the front of Cabra College and thought they were liquid amber then saw this footage and realised they were plane trees
The bark on the plane trees is great imo .... looks like army camo
Later in the year, have a look around the area you found the seed pods and you should see seedlings come up. Collect them and grow on in a large pot for a few years
Thanks Ken
good advice.....will definitely check that out later in the year, however I have a suspicion that these trees are growing out of concrete footpaths, hopefully I can find a few
Yes Jacaranda it must be.
This is an Australian native.
Yes Jacaranda it is "cuwire," they are definitely not native.........Yes South America.....Brazil actually
In conclusion if I come across some pods/seedlings later in the year I think I will have a crack at growing them......I have nothing to lose and only experience to gain
. If you are in Adelaide this tree can be found lining the road along Fullerton road, from cross roads to greenhill road.
