Radermachera is a genus of about 17 species of flowering plants in the family Bignoniaceae, native to southeastern Asia. They are evergreen trees reaching 5–40 m tall, with bipinnate or tripinnate leaves, and panicles of large bell-shaped, white, pink, pale purple or yellow flowers 5–7 cm diameter.

The genus is named after Jacob Cornelis Matthieu Radermacher, the 18th century Dutch naturalist who cataloged much of the flora of Java and Sumatra.

Cultivation and uses

R. sinica has become a popular houseplant, grown for its decorative foliage.

Radermachera sp. 'Kunming' sold under the tradename 'Summerscent' is a fast growing, scented, trending plant in Australia. Useful as an informal screen (pruning aggressively after flowering) or a small tree if trained to a single trunk (cinture before flowering to maximise flower production and reduce crown after flowering).
