This page has a good overview:

>...its ability to sprout prolifically from adventitious buds on stems and roots allows it to survive fire, cutting and even bulldozing in construction areas; making it difficult to remove from established areas.

> Cutting or girdling trees with power or manual saws are effective at preventing seed production, but an herbicide treatment is necessary following cutting since Paulownia readily re-sprouts. Hand pulling may be effective for young seedlings. Plants should be pulled as soon as they are large enough to grasp. Seedlings are best pulled after a rain when the soil is loose. The entire root must be removed since broken fragments may re-sprout. Cutting or pulling is the preferred mechanical treatments of the Paulownia tormentosa; do not use fire because this species is able to survive fire and then quickly proliferates and out-competes native tree species post-fire.

They mention it’s “easy to regrow from the stump” what that means is cutting it down doesn’t kill it. Additionally many trees that easily regrow from a cut stump also regrow/produce new tree from their roots.

Seems like a recipe for an invasive plant (much like those awful pear trees the were used for landscaping)

After one research it seems like only one variant of Paulownia is "invasive" - as in super aggressively spreading, but it does make me wonder if have acres and acres filled with them will result in some mutant offspring developing the super aggressive spread that the species is clearly capable of. Very much like what happened with that invasive pear [1]

It also seems handy for growing timber. There seems to be a growing market for it too. https://thisnzlife.co.nz/how-a-small-waikato-farm-harnesses-...

It's in a caption of one of the images:

> "After the first year of growth, trees are cut down to the stump, the rest sold for timber. This process, called coppicing, promotes bigger and straighter growth the following year."

That should be a method of carbon sequestration.
