We have these retched trees as street trees, in almost all of the old Melbourne suburbs. I would not plant this tree in your garden

i would not plant this tree anywhere! The round seed ball when it matures becomes fluffy causing asthma attacks. Personally it hits the back of the throat causing violent coughing fits. All this fluffy gets blown around clogs up gutters. It self seeds in the garden very easily. If I could I would poison n cut them all down and have the biggest street bonfire. I know I am not alone in this thinking many people in Melourne are affected by them, why they still plant them is a mystery.

I love seeing the mobs of Corellas come thru destroying the seed balls. The streets look like they are covered in snow

for me it means a season without being choked everytime I go into the yard.
Cheers
