This guide explores everything you need to know about Paulownia wood, from its characteristics and uses to its environmental benefits, helping you decide whether it’s the right choice for your next project.

What is Paulownia Wood?

Paulownia wood comes from the Paulownia tree, a fast-growing deciduous species native to Asia, often referred to as the “Empress Tree” or “Princess Tree.” Known for its striking purple flowers, the tree grows quickly and regenerates after harvesting, making it an eco-friendly timber choice.
