Koelreuteria bipinnata, commonly known as the Chinese Flame Tree, is a deciduous ornamental shade tree grown for its bold seasonal display. Through late summer and into autumn it carries large, airy sprays of golden-yellow flowers, which give way to its signature feature: showy papery seed capsules that flush pink to salmon-red and hang like clusters of small lanterns across the canopy.
Its foliage is large and bipinnate, finely divided into many leaflets for a soft, fern-like texture, turning warm yellow tones before dropping in winter. Mature trees form a rounded, spreading canopy around 6 to 9 metres tall and wide, making Koelreuteria bipinnata an excellent medium shade, feature or street tree.
It grows in full sun to part shade and prefers well-drained soil, adapting well to a range of soil types and to urban conditions. Moderate growing and low-maintenance, Koelreuteria bipinnata is drought tolerant once established and frost tolerant when mature, though young trees benefit from protection through their first cold seasons.
