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 ...

Paulownia catalpifolia is a species of flowering plant in the family Paulowniaceae, native to Shandong province, China, and introduced to Hungary. [1] An extremely fast-growing tree, it is cultivated in China for its timber. [2] [3]
The light purple flowers bloom from May to June; while the flower of Paulownia tomentosa has purple stripes, that of Paulownia coreana does not. The flower has five divided petals, each 5–7.5 cm (2–3 in) in length. The tree bears light brown fruit from October to November; the fruits are elliptical, with sticky puffs.
