Paulownia tomentosa is a tall broadleaf deciduous tree that is native to Western and Central China. This tree also popularly known as princess, empress or foxglove tree was named in honour of Princess Anna Paulowna of Russia.
Paulownia tomentosa
It is a handsome, fast-growing, invasive tree that reaches heights of 30 to 70 feet at maturity.
What is Paulownia Tormentosa?
Paulownia tomentosa has large, wide, heart-shaped green leaves that are situated on both sides of the stem. The edible large leaves are 15-30 cm long and wide and can grow even larger. The large, purple, fragrant flowers grow on long upright panicles that are 10-30 cm long and bloom before the leaves emerge in spring.
Clusters of tiny, dry fruits that change colour from green to brown as they mature are produced by the tree and these fruits produce millions of seeds that spread easily in wind and water. Its thick, pervasive and pernicious roots can cause damage; thus, the roots and seeds of the Empress tree are considered the most invasive parts of the tree.
