Synonym(s): princess tree, royal paulownia, royal empresstree

Princesstree is a deciduous tree that grows to 60 ft. (18.3 m) in height and 2 ft. (0.6 m) in diameter. Leaves are opposite, 6 to 12 in. (15.2-30.5 cm) long, heart-shaped (sometimes with three shallow lobes) and hairy on the underside. Flowering occurs in the spring, when showy, 1.5-2 in. (3.7-5 cm) long, tubular, pale-violet flowers develop in upright clusters. The pecan-shaped fruits occur in terminal clusters and split to release thousands of seeds. The thin, fruit capsules persist well into winter. Princesstree usually invades roadsides, stream banks, forest edges and other disturbed areas, but has the ability to invade a wide variety of places. Once established, it is difficult to remove due to prolific seed production and its ability to resprout vigorously. It is native to eastern Asia and was first introduced into North America in the early 1800s for ornamental purposes and as a potential export for carving wood.
