Hi brical 1,
I took these Pics at Stanthorpe last month.
I am going back there ( Girraween ) weekend after next.
It they have already developed seed pods I will get you a bag full.
I did not notice much scent.
From my Pic profile, I can see the Pic was taken at 6.55 am, maybe the scent comes when it warms up a bit ?
Stanthorpe is still about 4 to 6 deg. at that time of the morning.
Funny you should mention railway lines Thats where I saw it.
