Do you know? If so, it would be good to tag it so it appears in the database as an example of how the tree can be used in a landscape. If not, you could perhaps post this in the Plant ID forum to get an identity, then you could tag it. This is a lovely photo and it would be nice for it to have more exposure.

I do not know the complete name of the tree.
I think it is an Australian Eucalypt and it was along a path by the wetlands at our previous home in Encounter Bay South Australia.
We have now moved so am unable to identify it further.
Thanks for your interest.
