Cultivation and uses

Radermachera 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).
