The fruit is a dry egg-shaped capsule 3–4 centimetres (1 + 1 ⁄ 8 – 1 + 5 ⁄ 8 in) long, containing numerous tiny seeds. The seeds are winged and disperse by wind and water. Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth.

There is a section that reads "Paulownia is known to be an early colonizer of sterile soils (such as after a high temperature wildfire), because its seeds are easily killed off by soil fungi. In fact, it is so difficult to start Paulownia by seed that successful plantations purchase rootstock or seedlings—or propagate their own.
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.
