"Cereoid+10" expounded:

You must have seen the only non-invasive Paulownia tomentosa on the planet
or else you are confusing it with a Catalpa.

Not at all, it's definitely a Paulownia. But I'm in a colder range
and I don't think they do well around here, generally. This one is
protected a bit, by terrain.

After it flowers and fruits, the dust-like seed of Paulownia tomentosa are
spread far and wide by the wind.

I guess they just don't germinate well around here. I know they are
problematic in other areas, never said they weren't.
