Paulownia (/pɔːˈloʊniə/ paw-LOH-nee-ə) is a genus of seven to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, in the order Lamiales. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea where they are native.
It was introduced to North America in 1844 from Europe and Asia where it was originally sought after as an exotic ornamental tree. Its fruits (botanically capsules) were also used as packaging material for goods shipped from East Asia to North America, leading to Paulownia groves where they were dumped near major ports. The tree has not persisted prominently in US gardens, in part due to its overwintering brown fruits that some consider ugly.[1] In some areas it has escaped cultivation and is found in disturbed plots. Some US authorities consider the genus an invasive species,[2] but in Europe, where it is also grown in gardens, it is not regarded as invasive.
The genus, originally Pavlovnia but now usually spelled Paulownia, was named in honour of Anna Paulowna, queen consort of The Netherlands (1795-1865), daughter of Tsar Paul I of Russia. It is also called "princess tree" for the same reason.[3]
Paulownia trees produce as many as 20 million tiny seeds per year. However, the seeds are very susceptible to soil biota and only colonize well on sterile soils (such as after a high temperature wildfire). Well-drained soil is also essential. Successful plantations usually purchase plants that have been professionally propagated from root cuttings or seedlings.[4] Although seeds, seedlings, and roots of even mature trees are susceptible to rot, the wood is not and is used for boat building and surfboards.
Trees can grow to maturity in under 10 years and produce strong, lightweight timber, good as firewood, with an even higher strength to weight ratio than balsa wood
