I think its nickname is Tree of Heaven.

In my family, we've always called it Poverty Tree - it seeds itself
everywhere, and is particularly noticeable in poor, neglected, rundown
inner-city areas.
It grows in vacant lots, in cracks in the pavement, in rain gutters,
between bricks in walls, it crowds out more attractive plants along
motorways...

I hate it.

The nickname came about because of its great height, I think. It's
amazing how many things are one country's weed and another's cherished
plant. We grow and sell Lonicera involucrata and I believe it's regarded
as a real nuisance in parts of USA. That's just one example of many, of
course!

When I returned to the UK after many years away, I was
amazed/astounded/horrified to see that the Botanical Gardens in
Edinburgh featured Ailanthus!
Lythrum salicaria (Purple loosestrife) is causing problems in parts of
the US, where it is out-competing native plants.
