In a Nutshell:
* Paulownia tomentosa (also known as the Empress Tree, Princess Tree or Foxglove Tree; pao tong ?? in Chinese; kiri ? in Japanese) is a deciduous tree in the genus Paulownia, native to central and western China, but invasive in the US. 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.
* Can grow 10' in a year, brittle wood, flowers pale violet with dark spots and yellow stripes inside, very much resemble foxgloves, flower buds often killed during winter in cold areas, prefers deep moist soil but tolerates many sorts, full sun or part shade, protect from wind, has naturalized throughout much of the East.
* The leaves can be mistaken for those of the catalpa. more...
* The wood is not attacked by insects. Used for making boxes, clogs, furniture, musical instruments etc. Good for posts and beams in construction. A source of charcoal. more...
* This can survive down to Zone 5 (may not flower), but thrives most favorably in Zones 7-10.
[ edit ] Description Flowers and young leaves Twig with old seed pods The flowers are produced before the leaves in early spring, on panicles 10–30 cm long, with a tubular purple corolla 4–6 cm long resembling a foxglove flower. The fruit is a dry egg-shaped capsule 3–4 cm long, containing numerous tiny seeds . The seeds are winged and disperse by wind and water. Pollarded trees do not produce flowers, as these only form on mature wood. 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.
