A tree with sturdy, thick, protruding branches that produce a curvaceous crown shape. The bark is greyish brown, later becoming rough. Young branches are thick and have velvety hair. Older branches become bare and hollow. The leaves are often equally wide and long and sometimes up to 40 cm in fully robust trees. They feel velvety because of hairs on the top and bottom. The leaf stem can grow up to 20 cm long. Shortly before the leaves appear, the flowers bloom in terminal, branched plumes. The flower heads have soft hairs and are light brown in colour. They start in the previous summer, creating a risk that they can freeze during a harsh winter. The flowers are a bright lavender blue and 5 - 6 cm long. Paulownia requires a sheltered site.
