Paulownia tomentosa

 is a deciduous tree in the genus Paulownia, native to central and western China.
 It grows to 10–25 m tall, with large heart-shaped to five-lobed leaves 15–40 cm across, arranged in opposite pairs on the stem. On young growth, the leaves may be in whorls of three and be much bigger than the leaves on more mature growth.
The leaves can be mistaken for those of the catalpa. The characteristic large size of the young growth is exploited by gardeners: by pollarding the tree and ensuring there is vigorous new growth every year, massive leaves are produced (up to 60 cm across). These are popular in the modern style of gardening which uses large-foliaged and "architectural" plants. Regarding its nomenclature.
Paulownia tomentosa can survive wildfire because the roots can regenerate new, very fast-growing stems. It is tolerant of pollution and it is not fussy about soil type. For this reason it functions ecologically as a pioneer plant. Its nitrogen-rich leaves provide good fodder and its roots prevent soil erosion. Eventually, Paulownia is succeeded by taller trees that shade it. It cannot thrive in the shade of other trees.
