Before I planted any Paulownia on my small area here in West Clare, Ireland, I did a couple of years of research, and although I had heard a few references here and there to their invasiveness, I couldn’t find any actual evidence that they are.
Certainly not in Ireland or cool temperate climates.
The climate can be a bit of a downside in Ireland; my feeling (not backed up by research) is that Paulownia do best in climates that have hot summers, 30ā plus.
This said, a couple of fellow enthusiast have said, that with full sun and good husbandry, their Paulownia have grown three metres in one season.
