	Invasives Plant Pests Literature Collection: Royal paulownia
		Abstract: Susceptibility of Paulownia elongata S.Y. Hu (princess tree) to Agrobacterium tumefaciens and A. rhizogenes was demonstrated by inoculating in vitro shoots.
		The age distribution of P. tomentosa was unimodal with a strong peak in the 18 and 20 year age classes, demonstrating a major recruitment pulse in the early 1970s correlated with the passage of Hurricane Camille (August 1969).
		Paulownia tomentosa had the lowest importance value (= 15.1) among the four dominant forest trees of the study area (Liriodendron tulipifera = 30.1, Betula lenta = 28.5, Platanus occidentalis = 16.0).

	Paulownia tomentosa - mediterranean climate gardening throughout the world (Site not responding. Last check: 2007-10-10)
		Apparently the remote native habitat of Paulownia tomentosa is that of the famous Dawn Redwood (Metaseqouia) and Ginkgo, but all of these have found a place in cultivation throughout the world.
		While Paulownia is an invasive weed threatening native lands in some wetter, temperate or sub-tropical parts of the world, this is seldom a problem in mediterranean climates.
		In some areas, especially where its hardiness may be in question, it is often 'stooled' annually, after producing 12-15ft stems with huge leaves (up to 2ft) and a very handsome, 'tropical' effect the year before.

	Paulownia tomentosa - Wikipedia, the free encyclopedia
		Paulownia tomentosa (also known as the Empress Tree, Princess Tree or Foxglove Tree; pao tong 泡桐 in Chinese) is a deciduous tree in the genus Paulownia, native to central and western China.
		Paulownia tomentosa can survive wildfire because the roots can regenerate new, very fast-growing stems.
		Eventually, Paulownia is succeeded by taller trees that shade it.

	Paulownia tomentosa
		Native to China, royal paulownia (empress tree or princess tree) is a fast-growing, deciduous tree that is primarily grown for its profuse spring bloom of foxglove-like flowers and its large catalpa-like green leaves.
		It was first introduced into the United States in the mid 1800s, and has since escaped cultivation and naturalized in many areas of the eastern U.S. It is an upright to spreading deciduous tree that typically grows to 40’ tall with a rounded crown.
		Paulownia is currently included in the family Scrophulariaceae (flowers resemble foxgloves), but has been included by some experts in the genus Bignoniaceae (flowers and foliage resemble catalpa).

	Princess Tree, Paulownia tomentosa - Southeast Exotic Pest Plant Council Invasive Plant Manual
		Paulownia is native to western and central China where historical records describe its medicinal, ornamental, and timber uses as early as the third century B.C. It has been cultivated for centuries in Japan where it is valued in many traditions.
		Paulownia has a hollowed or chambered pith, while that of the catalpa is solid and whitish.
		Paulownia trees are often found on roadsides, stream banks, and disturbed habitats, including fire sites, forests defoliated by pests (such as gypsy moths) and landslides.

		Language: English Descriptors: Lumber; Air drying; Paulownia tomentosa; Air drying; Product quality; Defects in wood Abstract: Lumber sawn from 10- to 14-year-old paulownia (Paulownia tomentosa) trees was studied to determine quality after air-drying as indicated by defect development and air- drying rate.
		Paulownia is dimensionally stable with an average volumetric shrinkage (green to ovendry) of 5.9 percent, a value lower than any native, commercial hardwood.
		Paulownia is dimensionally stable and concern about drying defects, regardless of growth ring orientation, is not necessary in air-drying, unless the pith is present.

	Paulownia - The Empress Tree and Fast Growing Nursery Plants for Home and Garden
		There are several species of Paulownia - Paulownia elongata, Paulownia kawakamii, and Paulownia tomentosa, all native to China, and have been planted in the US for many years.
		What's popular about the Paulownia is that they grow very fast, where 8 to 12 feet a year is considered common, some sources have had growth of 15 to 18 feet in a year!
		The Paulownia also has large ten inch long masses of fragrant violet to dark blue flowers that come out between April and May. The Paulownia tends to be medium sized trees, where the Paulownia kawakamii gets up to 30 to 40 feet, and the Paulownia tomentosa gets 40 to 60 feet tall.

	Royal Paulownia Tree (Paulownia Tomentosa)
		Highly prized for its easily-worked wood and its ability to establish a quick canopy, this tree with leaves as large as a meter wide is condemned as an invasive weed by some outside its native China.
		Yet this enigmatic tree is difficult to propagate, seeming to prefer to establish itself in the parking lots of abandoned filling stations and other exhausted soils.

		It easily adapts to disturbed habitats, including previously burned areas, forests defoliated by pests (such as the gypsy moth) and landslides and can colonize rocky cliffs and scoured riparian zones where it may compete with rare plants in these marginal habitats.
		Enriched in nutrients, paulownia leaves and flowers were good fodder for pigs, chicken, sheep, cattle and rabbits and so on.

	Question about Paulownia Tomentosa... - Trees Forum - GardenWeb (Site not responding. Last check: 2007-10-10)
		I read Paulownia is a weedy tree and the branches grow too wide and break easily, but then I see pictures of them lining streets, large trees with a perfectly balanced crown...
		Or maybe it has something to do with P. tomentosa being known in two types in cultivation, the typical P. tomentosa and the much more prevalent (here, anyway) P. tomentosa 'Lilacina'.
		Paulownia Kawakamii as bboy mentioned is probably the answer...
