Paulownia tomentosa. Paulownia is a genus of angiosperm trees, and one of the fastest-growing trees in the world. [12] Paulownia tomentosa can grow over 30 metres (98 ft) tall and has large heart shaped leaves ranging from 10–20 centimetres (4–8 in) wide and 15–30 centimetres (6–12 in) long with a 10–20 centimetres (4–8 in)-long petiole.

Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth. [15] [16] It is tolerant of pollution and can tolerate many soil types. It can also grow from small cracks in pavements and walls. Paulownia can survive wildfires because the roots can regenerate new, very fast ...
Paulownia elongata is planted as a forestry tree producing strong, yet light, wood. It is grown for lumber in North America and China. Commercial plantations are normally established from selected clones resulting from micropropagation. [1] They are known to grow up to 15 feet (4.6 m) or more in the first year.

They are a small genus of two species in Southeast Asia, that can grow as a shrub or tree, or as hemiepiphetic pseudo-vine. [8] There are still morphological characters as well as nuclear genome data to support Wightia as sister to Paulownia leading it to be of proposed hybrid origin from Phrymaceae and Paulowniaceae. This theory, based on ...
