Paulownia tomentosa

Paulownia tomentosa, common names princess tree, empress tree, or foxglove-tree, is a deciduous hardwood tree in the family Paulowniaceae, native to central and eastern China and the Korean Peninsula. It is an extremely fast-growing tree with seeds that disperse readily and is considered an invasive exotic species in North America that has undergone naturalisation in large areas of the Eastern US, even though it might be able to successfully get established through seeds only under ideal conditions. P. tomentosa has also been introduced to Western and Central Europe, and is establishing itself as a naturalised species there as well.
